3. Intended purpose and intended users

3.1 Intended purpose

CAD software for preparation of digital dental models for orthodontic and prosthetic appliance manufacturing. Not for diagnostic use. For professional use only.

DentVIS is a tool for visualizing and editing 3D dental models. It is used to prepare digital models (for example setup models and models for 3D printing or thermoforming) that serve as a basis for manufacturing appliances.

3.2 What the software does not do

The software does not provide diagnostic or therapeutic recommendations and does not establish a diagnosis.
The software does not evaluate the position of teeth and does not automatically determine tooth movements. Every tooth position and every goal on the timeline is set by the user; intermediate steps are calculated only as an interpolation between the positions entered by the user, limited by the step size set in Settings.
The tooth axes are the default geometric coordinate frame of each segmented tooth, tuned manually by the user. They are not anatomical measurements.
The roots displayed with HIDE GUM or Show roots are schematic template shapes for orientation only; they do not represent the real roots. While they are shown, the short closure of each tooth below the crown margin is not drawn, so the crown continues directly into the schematic root.
All clinical decisions remain the sole responsibility of a qualified healthcare professional.

3.3 Intended users and environment

Users: qualified dental professionals — dentists, orthodontists and dental technicians — trained in digital dental workflows. The software is not intended for laypersons.
Training: no formal training is required. Users must read these instructions and should practise with the demo case before working on real cases.
Environment: dental practices, dental laboratories and educational institutions; office conditions on a computer or iPad.
Persons whose models are processed: the software has no contact with any person. It processes 3D scan files of dental arches provided by the user.

3.4 Contraindications and clinical benefit

Contraindications: not applicable — the software is a CAD tool and has no direct diagnostic or therapeutic effect.

Clinical benefit: indirect — efficient and reproducible preparation of digital dental models used for appliance manufacturing. The software itself does not act on the human body.

4. Safety information

4.1 Warnings

Do not use the software as the sole basis for clinical decisions. A qualified professional must review every output before it is used.
Review every model before manufacturing. Exported models are a basis for appliance manufacturing, not a finished device. Check the shape, the tooth positions, the base, the trim line and the scale of each exported file in your printing or milling software before production.
Verify the jaw assignment. On the New case screen the software places each scan file in the UPPER JAW or LOWER JAW tile by the file name, otherwise by the model shape (palate). This is a file assignment only, not an evaluation of the teeth, and it can be wrong. Check every tile in its 3D preview and correct the assignment with Swap or Replace. A swapped assignment becomes visible only later in the workflow.
Verify the model after import. Imported meshes are automatically repaired and simplified (removal of defects, closing of small holes). Check visually that the model represents the scanned situation before you continue.
Check the tooth outlines. Automatic detection of tooth boundaries can be wrong, for example at bridges, crowding, restorations, scan holes or fixed retainers. Review and correct every outline in step 2 · Check outlines.
Displayed values in mm and °. Values show the position set in the model — not a measurement. They are not calibrated measurements; use calibrated instruments for any clinical measurement.
Check the steps. Intermediate steps are an interpolation between the positions you entered. Review every step on the timeline, including collisions, before export.

4.2 Precautions

Keep the software up to date. Cases saved with a newer version cannot be opened by an older version. Use the same version on all devices that share cases.
Cloud synchronization is not a backup. Back up your case files (.vis) and exports regularly.
Use a neutral case label. Do not enter names or other data identifying the person to whom the model belongs in the case name, notes or file names.
Steps that have been exported are locked. If you need to change them, the change must be exported again and the earlier files must not be used.
Do not close the application while a case is being saved, exported or synchronized.

4.3 Residual risks

After all risk control measures, the following residual risks remain. They are acceptable when the warnings above are followed:

The software cannot verify that an imported scan or an exported file belongs to the case; label cases, files and printed models unambiguously, without data identifying a person.
The pre-assignment of a scan file to the upper or lower jaw (by file name or model shape) can be wrong; a swapped assignment that is not corrected on the New case screen may become apparent only later in the workflow.
The software does not check the units or the scale of imported scans; use scans in millimetres and verify that the model dimensions are plausible.
Imported scans are automatically simplified and repaired (fewer triangles, removal of separate fragments, closing of holes), which can remove fine surface detail.
Tooth outlines found by Detect can deviate from the actual tooth margins, especially at retainers and fused or crowded contacts.
The coloured preview of the teeth during segmentation is approximate; the final segmentation can differ from it.
In rare cases the cut can follow a slightly different path than the displayed outline; inspect the segmented crowns after Confirm.
When the teeth are built, the edge of the gingiva next to each tooth is placed onto the tooth surface automatically, and gingiva that would cover the crown above the tooth outline is moved below the outline (towards the root); this changes the gingiva only next to the teeth — check the gingival margin in the exported models.
Where you remove a tooth, the gingiva over its place is closed with a smooth surface; check this area in the exported models.
When the teeth are built, each crown above the tooth outline is kept as scanned, including the contacts between the teeth; only scan points that two neighbouring crowns share at a contact are moved apart by 0.003 mm so that the exported models remain valid.
Tooth numbers and the occlusal plane are derived from the teeth you tap; wrong or missing marks lead to wrong numbering or a tilted model.
Tooth axes are a default geometric frame of the segmented tooth that you tune manually; they are not anatomical axes.
Roots shown in the software, and the short closure of each tooth below the crown margin that follows the cross-section of a schematic root, are schematic construction geometry and must not be used to judge root position.
All values in mm and degrees are given in the software’s own coordinate frame. Values show the position set in the model — not a measurement.
Collision indication is a visual indication of overlapping models; collisions can be missed, and the displayed overlap values are approximate and are not a prescription for enamel reduction. Values show the position set in the model — not a measurement.
Intermediate steps are a linear subdivision of the movement between your goals; the software does not assess whether the change per step is biologically appropriate.
Attachments, pontics and twin-block parts are placed only where you place them, and pontics have a simplified generic tooth shape, not the shape of the missing tooth; check them in every exported step.
The occlusion setting is a manual position of the lower jaw that you define; the displayed values are not a bite registration. Values show the position set in the model — not a measurement.
Reference models and arch forms in Compare are visual references only. Their placement over the crowns is approximate and is not an assessment; they are not a target shape and they never change the case or the long axes.
Base height, hollow models, printing supports and the case label change the printed geometry; verify every exported model before printing.
Only the steps you select are exported and files are named by their step number; verify the exported set and the file names before manufacturing.
The trim line for trimming machines follows the gingival margin and is smoothed; it does not avoid pontics and must be checked before trimming.
Build-plate files are arranged automatically; models that are too large or too tall are only listed in the export summary.
Cloud synchronization is not a backup; when two versions of a case differ, choose the version deliberately.
An unexpected shutdown can lose changes made since the last automatic save.
Cases saved by a newer version cannot be opened by older versions.
Case data are stored on the device without additional encryption by the software and remain there after you sign out.
The user interface is available in English, Czech, German, French, Spanish, Italian and Polish (account menu → Language; applied after restart). Texts without a translation are shown in English.
On iPad, large scans and long operations can be slow, and precise editing on a small touch screen requires care.
Deleting a case removes it from this device and, for cloud cases, from all devices; this cannot be undone.

6. Getting started

6.1 Start screen and sign in

When no account is signed in, DentVIS starts on the 3D VIEWER start screen. It offers:

Open .vis file — opens a DentVIS case file (.vis) for viewing: you can rotate the models, zoom in and play every step, but you cannot edit the case (read-only). On a computer, you can also drop the .vis file anywhere on this screen.
Try the demo case — opens the demo case for viewing (read-only).
Sign in (top right, next to Have an account?) — opens the sign-in screen. Sign in with the e-mail address and password of your DentVIS account.

The sign-in screen also offers Open a .vis file — no account needed.

If you have forgotten your password, tap Forgot password? on the sign-in screen. On the Password reset screen enter the Email address of your DentVIS account and tap Send instructions; you receive an e-mail with instructions to reset your password. Back to sign in returns to the sign-in screen.

6.2 Important notice and legal documents

On first sign-in, and whenever the documents change, the application shows the Important Notice with the intended purpose and the classification. Read it, confirm the notice, the Terms of Use and the Privacy Policy, and tap Continue. Updated documents are shown in the Updated terms dialog.

6.3 Register the device for editing

Editing cases is allowed on registered Editor devices. The number of Editor devices depends on your plan. If the current device is not registered, the dialog Edit on this device? appears: tap Register this device, or Sign out. A registered device can be swapped once every 30 days; contact support if a device is lost or broken.

6.4 First use: quick setup, setup speed and tour

After sign-in, DentVIS guides you through the first use. The progress of the guide is saved with your account, not with the device.

New account. A new account goes through three parts:

Quick setup (Step 1 of 2): choose the Language of the user interface (applied after restart) and your Printer (the exported models are laid out on its build plate, see 12.4). Tap Save and continue, or Skip to keep the current settings. Both can be changed later: the language in the account menu → Language, the printer in the export settings.
Setup speed (step 2 of 2, required): check and confirm the values as described below.
The main screen shows the Getting started card.

Existing account. Once after the update to version 3.0.4 or later, an existing account is shown only the required Setup speed confirmation (Required once · applies to new cases). After Confirm, DentVIS offers a short tour of the new look on the demo case: Start tour or Later. The tour can also be started later from the account menu → Take the tour.

Setup speed confirmation (required)

The setup speed is the largest change of a tooth position between two steps. DentVIS calculates the number of intermediate steps between your goals from it (see 11.1). Because the default values may not match your practice, this step cannot be skipped; the window is shown again until the values are confirmed.

Check the six values: Translation per step — Right / Left, In / Out, Up / Down (mm); Angles per step — Rotation, Inclination, Torque (°). Change a value with − / + (0.05 mm or 0.5° per tap). Values show the position set in the model — not a measurement.
Tick I have checked the values and they match my practice. Only then does Confirm become available.
Tap Confirm. The values are saved as your default setup speed for new cases. Existing cases keep their own setup speed.

You can change the values later in the Virtual Setup under Settings → Setup speed (see 11.6).

Warning: Confirm only values you have checked. The number of intermediate steps, and with it the change of the tooth positions per step in every exported model, follows from the setup speed. Review the steps on the timeline before export.

Getting started card

For a new account, the main screen shows the Getting started card (Welcome to DentVIS) with Start tour, Instructions for Use (opens these instructions) and Hide guide. Your progress lists four steps; each step is ticked off when you have done it:

Quick setup — language, printer and setup speed.
Tour on the demo case — Start tour.
Create your first case — New case (see section 9).
Set a goal and export — a goal on the timeline and the first export (see section 12).

The card is shown until all four steps are done. Hide guide hides it; the account menu → Getting started shows it again.

Tour

Start tour (on the card or after the setup speed confirmation) or the account menu → Take the tour opens the demo case and explains the Virtual Setup in seven steps: 3D view, Move teeth, Timeline and steps, Markers, Collisions, Notes and Export. The element being explained is highlighted and can be used. Next and Back move between the steps, Finish ends the tour and Exit (or the Esc key) leaves it at any time.

Tips

The first time you open Markers, Occlusion, Compare or Settings in the Virtual Setup, a short tip is shown next to the panel. Got it closes the tip; Don't show tips switches all tips off for your account.

Note: The guide, the tour and the tips explain how to operate the software. They do not replace these instructions.

7. Main screen and case management

Search cases — filters the case list by case name.
Open .vis — opens a DentVIS case file from disk. If the case is already in your list, you can open the existing case or import a copy.
New case — creates a new case (see section 9).
Categories — New Cases, Active Cases, Discontinued Cases, Demo Cases.
Case card — shows a preview, the case name, the date and the synchronization state. Tap the card to open the case.
Case name at the top of an open case — tap the name to rename the case (also in Export); Enter or ✓ saves, Esc cancels. Use a neutral designation (for example an internal case number). The new name is also used for the case name embossed in the base and for the case in the cloud. A case renamed in the case list shows the new name the next time it is opened.
… on a case card (or right-click / long press) — Open, Rename, Move to (category), Duplicate, Select (then tap other cases to add them to the selection and move them to a category or delete them), Delete.
Account menu — plan and devices, Settings, Language, Getting started and Take the tour (see 6.4), Manage license, About DentVIS, Log out.
Settings (account menu) — cards Account (Plan, Valid until, Device limit, Editor devices, This device, Credits on per-case plans; buttons Manage license and Log out), Language, Cloud sync (synchronization state, when known) and About (About DentVIS, Privacy Policy, Terms of Use).

Caution: Delete removes the case from this device and from your cloud cases on all devices. This cannot be undone.

8. Workflow overview

Case — create a case and add the upper and/or lower jaw scan.
Segmentation — tap teeth → Detect → check outlines → long axes → Confirm.
Virtual Setup — set tooth positions and goals on the timeline; add markers.
Review — check every step, collisions, occlusion and notes.
Export — STL for 3D printing, build plate, trim line, or the .vis project.

All work is saved automatically with the case. Undo and Redo are available at the bottom left of the screen.

9. Creating a case

On the main screen tap New case. The New case screen opens.
Add one or two scan files (STL, PLY or OBJ): on a Mac drag them onto the screen (Drop the jaw scans here), or tap Choose files and select them.
The software reads the files and places each one in the UPPER JAW or LOWER JAW tile — by the file name (for example upper / lower, maxilla / mandible; green note Recognized by file name), otherwise by the model shape (an upper jaw scan usually includes the palate; orange note Recognized by shape — please check). Each tile shows a 3D preview, the file name and the number of triangles.
Check every tile: drag the preview to rotate the model (Drag to rotate). If the scans are in the wrong tiles, tap Swap. Replace chooses a different file for one tile, the trash icon removes the scan; a case can also have one jaw only (the empty tile offers Choose file; if you select both scans there, they are assigned as when dropped). When a model’s shape clearly does not match its tile, the tile shows Shape looks like a lower jaw — please check (or … an upper jaw …).
Under Case name the software fills in Case and today’s date (dimmed until you change it). Use a neutral label (for example an internal case number).
Tap Create case. The case opens in tooth segmentation. Create case is dimmed until at least one jaw scan has been added and the case name is not empty. Cancel or × (top right) closes the screen without creating the case.

When an existing case is edited, the screen Edit case opens instead: change the case name or the jaw scans and tap Save changes; Delete case deletes the case after confirmation (see the caution in section 7).

Warning: Check in the 3D preview that the upper jaw scan is in the UPPER JAW tile and the lower jaw scan in the LOWER JAW tile, also when the note is green. The assignment by file name or shape is only a pre-assignment of the files; you confirm it with Create case.

10. Tooth segmentation

Segmentation separates the individual teeth from the scan. It has three steps shown in the card on the left. Switch between jaws with Upper jaw / Lower jaw at the top of the card.

10.1 Step 1 · Tap teeth

The card shows the tooth number (FDI notation) to tap, for example 21. Tap that tooth on the model. A ball marks the tooth and the arch diagram shows its state. The tapped tooth is shaded; the shading fades out towards its edge because it is only a preview — the exact tooth boundary is shown by the outline in step 2.
If the tooth is missing, tap Skip. Back returns to the previous tooth.
Optional: open Detection to change, for the current tooth, the Margin sensitivity (Low / Medium / High) and the Tooth size.
When all teeth are marked, tap Detect. The software detects the boundary of each tooth from your marks.

10.2 Step 2 · Check outlines

Each detected tooth is shown with its outline (blue line); neighbouring teeth have different colours.

Check every outline from several views. The outline must follow the gingival margin of the tooth and must not cut into the neighbouring tooth or the gingiva.
To correct an outline, tap the tooth and use the fix tool: Drag moves the outline points, Draw redraws a section of the outline on the model, Brush paints the tooth area with a circle around the finger, pencil or cursor — choose Add to enlarge the tooth or Remove to make it smaller and paint over the area; the outline follows the painted area and stops at the nearest groove on the surface. The Brush size slider sets the size of the circle, which is shown under the finger, pencil or cursor; Undo removes the whole stroke. Check every corrected outline from several views.
‹ Previous / Next › in the panel move to the outline of the neighbouring tooth — use them also to select a tooth that is hard to tap.
Back to teeth returns to step 1 (for example to add a missed tooth).
When all outlines are correct, tap Confirm.

Warning: An outline that is not corrected determines the shape of the separated tooth and of the gingiva in every exported model. If a tooth cannot be segmented, the message Failed to segment tooth NN appears: the outline must not pass through a hole in the model; fix the outline so that it passes over the hole.

10.3 Step 3 · Long axes

Each tooth receives a default geometric coordinate frame (long axis). The axis defines how the tooth rotates and tilts in the Virtual Setup.

The card shows the current tooth. Drag the axis on the model to adjust it; use Back / Next to move between teeth.
The card shows Mesial-distal tilt, Buccal-lingual tilt and Facial direction of the axis. Values show the position set in the model — not a measurement.
Optional: tap Compare and add STL models of the teeth of this jaw (and, if you have one, a model of the jaw). DentVIS places them semi-transparently over the crowns as a visual reference; a model of the jaw is placed in the same position. The long axes are not changed — set each axis yourself. The reference models are not saved in the case and are not exported.
Optional: switch on Show roots in the card. The gingiva is hidden and every tooth shows a schematic template root that follows the axis as you drag it. The root is a template shape along the axis you set, not the real root. The displayed root is not saved or exported; only its cross-section just below the crown margin shapes the closure of each tooth (see the next step). The gingiva returns when you leave this step.
Tap Confirm. The teeth, the gingiva and the model base are built and the case opens in the Virtual Setup. Below the crown margin, each tooth is closed by a short shape that follows the cross-section of the schematic template root for its tooth type along the long axis you set, with its width between the teeth matched to the crown of that tooth; this is construction geometry of the model, not the anatomical root and not a measurement. The crown above the outline is not changed. Where the gingiva meets a tooth, its edge is placed slightly into the tooth surface and the gingiva next to it is smoothed, so that no gaps or folds remain between the gingiva and the tooth in the 3D view and in the exported models; the outlines you confirmed are not changed.

Note: A finished segmentation can be undone from the Virtual Setup. The dialog Undo the finished segmentation? warns that the jaw returns to curve editing and that later edits are discarded.

11. Virtual Setup

Header — case name and synchronization state; case lock; notes; Export; close the case.
Tool rail (left) — Move, Markers, Occlusion, Compare, Settings; Undo / Redo.
View buttons (top) — standard views (front, sides, occlusal) and which jaws are displayed.
Display switches (right) — COLLISION (contacts and overlaps between teeth; an overlap is shown with a minus sign, a gap between neighbouring teeth in blue), INITIAL (initial position overlay), FINAL (final position overlay), OCCLUSION, HIDE GUM (hides gingiva and base; shows schematic template roots).
Timeline (bottom) — Start, numbered steps, Final, Upper goal / Lower goal, play button.

11.1 Timeline, steps and goals

The timeline shows the initial state (Start), the steps and the final state (Final) for both jaws. A goal is a step in which you set the tooth positions yourself; the steps between goals are interpolated, and their number follows the maximum change per step set in Settings. Teeth that you removed do not move and do not add steps; in a case exported with an earlier version, the number of steps stays as it was.

Tap a step to display it. Tap Upper goal / Lower goal to add a goal for the jaw.
Tap the selected step again to open the step menu: Set as goal, Extend goal (hold the goal one step longer), Delete goal, Set upper goal / Set lower goal and Add note.
If you move teeth in a step that is not a goal, the dialog Teeth are not in a key step asks whether to move them in the current step.
The play button plays the steps as an animation.

Notes — notes can be written for the case and for individual goal steps. Open Notes from the header or with Add note in the step menu. A step with a note is marked on the timeline; notes are saved with the case.

11.2 Move

Tap Move and choose Tooth (individual teeth) or Arch (whole jaw).
Tap a tooth to select it; several teeth can be selected and moved together. The panel shows the change of the tooth in the displayed step against Start: Right / Left, In / Out, Up / Down (mm) and Rotation, Inclination, Torque (°). Values show the position set in the model — not a measurement.
Change the position by typing a value or using the step buttons in the panel, or by dragging the gizmo in the 3D view: arrows move the tooth, rings rotate it. While you drag the gizmo, the slider for the same movement appears in the panel; you can set the value with it too.
The pivot of the rotation is marked on the tooth with a highlighted ball. Change it in the Pivot row (Center, Edge, Mesial, Distal) or tap a white ball on the tooth.
Copy / Paste copy the tooth positions of the displayed step and paste them into another step.

Warning: Switch on COLLISION and check contacts and overlaps between teeth in every step before export.

11.3 Markers

Markers adds construction elements to the model.

Tooth tab: up to three marker slots per tooth. Choose a shape from Standard or Special, its Height (Low / Medium / High), place it on the tooth and adjust it in the 3D view; Remove deletes it.
Model tab: twin-block elements (Lateral, Occlusal — tap a block in the 3D view to move it) and pontics for gaps in the upper or lower arch. A pontic is a generic tooth shape that the software generates for the tooth number from a table of average crown dimensions; the shape is simplified (without surface detail). The pontic sits in the gap between the neighbouring teeth and its width follows the gap. It is construction geometry of the model — not the shape of the missing tooth and not a dental restoration. Cases saved with an earlier version open with the new pontic shape; the position of the pontic is kept.

11.4 Occlusion

Occlusion adjusts the position of the lower jaw against the initial bite. Switch between Initial and Modified, drag the lower jaw in the 3D view, or type values (left-right, up-down, front-back, tilts and rotation). Reset occlusion returns to the initial bite. Values show the position set in the model — not a measurement.

11.5 Compare

Compare displays reference models as a passive visual overlay. It does not change the case.

+ STL files loads reference models (for example an earlier scan); + Arch form adds an arch form (small, normal, wide).
For each model set the colour, visibility and Opacity. Selected models can be linked (Link / Unlink) and moved together, or removed.
Matching: drag a model in the 3D view to adjust the overlay; Reset matching returns it.
Large models (more than about 200 000 triangles) are reduced for display when they are added (Loading model). Reference models are not saved in the case and are not exported.

11.6 Settings

Settings → Setup speed sets the maximum change of a tooth per step: translation (right/left, in/out, up/down; default 0.25 mm) and angulation (rotation, inclination, torque; default 2°). The number of interpolated steps between goals follows these limits. Save applies the values to the case; Set as default uses them for new cases; the default for new cases is also set when you confirm the setup speed after sign-in (see 6.4). Values show the position set in the model — not a measurement.

12. Export

Tap Export in the header. The export screen shows the settings on the left, the model in the centre and the step selection on the right. The timeline shows which steps were already exported.

12.1 Format

STL · 3D printing — STL models of the selected steps.
Project · .vis — the complete case as a .vis file (for archiving or transfer).

12.2 3D printing settings

Orientation — Horizontal (flat) or Vertical (upright, with supports at the back of the model).
Upper base / Lower base — height of the model base in mm. Drag the balls in the 3D view to tilt the base. The base is at least 6 mm from the deepest crown edge; a new case starts at 7 mm. Values show the position set in the model — not a measurement.
Case name — None or In base (case name and step number embossed in the base; after the case is renamed, the embossed name is updated).
Model — Filled or Hollow.
Trim line — Manual, or Machine: a model with a machine base and a CSV file with the trim line for the selected trimming machine (Machine base).
Printer — optional: place the models directly on the build platform of a printer (see 12.4).

12.3 Steps to export

For each jaw choose Final, All, Remaining (not yet exported) or Range (From – To). Already exported lists earlier exports. Enter the File name (renaming the case at the top of the export screen also updates the default file name) and tap Export N files. Keep DentVIS open until the export is complete. While the models are being built, Cancel stops the export: no files are created, the steps are not marked as exported and the step you were on is shown again. The same applies if the export cannot be completed (for example, the disk is full): no files are created and the step you were on is shown again. If the hollow model cannot be created for a model, that model is exported filled and a message after the export lists it.

The export also contains the case report (<case> - Case report.pdf): diagrams of both arches with attachments and the places of collisions, collisions by step, a list of attachments and model parts, the case note and the step notes. The same report can be created at any time with PDF in the Notes panel. Values in the report are given in mm. Values show the position set in the model — not a measurement. The collision indication can miss contacts and is not a prescription for enamel reduction.

Warning: Exported steps are locked to protect the files already sent to production. Before manufacturing, open each exported file in your printing or trimming software and check the model, the base, the trim line and the scale. Never mix files from different exports of the same case.

12.4 Printer build plate

In Printer choose your printer (for example Formlabs Form 4, Bambu Lab H2D or others in the list). DentVIS places the exported models on the build platform of that printer in rows, flat or upright according to Orientation, and writes one file per plate: Plate 1 of N - <printer> - flat|upright as 3MF (or as STL files in plate coordinates, Plate file). The single model files are exported as before.

Caution: The summary after export reports models that are too large for the plate or too tall for the printer; those models are not placed. Always check the plate in the printer software (supports, orientation, spacing) before printing.

13. Cloud synchronization and multiple devices

Cases are stored locally on the device. With the Team plan, cases are also synchronized through the manufacturer’s cloud service to the other devices of your team. The state of each case is shown on its card.

A case can be edited on one device at a time. If it is open elsewhere, the dialog Case is open on another device offers Cancel, Try again or Open anyway (a new version is created).
If a newer version exists in the cloud, A newer version of this case is available offers Download new (the local version is backed up) or Use local version.
Without an internet connection, you can continue with the local version.
A new case name is also saved in the cloud; other devices keep the name they already show.

Caution: Synchronization is not a backup. Export important cases as .vis files and back them up.

14. Messages and what to do

Failed to segment tooth NN — the outline passes through a hole in the model. Fix the outline so that it passes over the hole (see 10.2).
Case is open on another device — close the case on the other device and tap Try again, or Open anyway.
A newer version of this case is available — choose Download new unless you know the local version is the correct one.
Case is locked — unlock the case in the header to make changes.
Teeth are not in a key step — you are editing an interpolated step. Tap Yes to move the teeth in the current step, or No.
No internet connection / Download failed — check the connection and try again, or continue with the local version.
Update required — this version is no longer supported. Install the update (iPad: App Store).
Case already in your list — the opened file belongs to a case in your list. Open existing keeps synchronization; Import as copy creates a separate case.

15. IT security and data protection

Use DentVIS only on devices that meet the system requirements and run an operating system that still receives security updates; install updates promptly.
Install DentVIS for macOS and Windows only from the download page (www.dentvis.com/download) and for iPad only from the App Store; do not bypass operating-system security warnings.
Keep DentVIS up to date; versions that are no longer supported are blocked.
Protect every device with its own user account, a strong password or passcode and automatic screen lock, and turn on full-disk encryption (FileVault, BitLocker, iPad passcode). DentVIS stores cases and sign-in data on the device without additional encryption.
On shared computers use a separate operating-system user account for each person; signing out of DentVIS does not remove cases stored on the device.
Use a unique password, never share your account and sign out on devices you do not use; if a device is lost, change your password and remove the device from your Editor devices.
Allow outgoing HTTPS (port 443) to the DentVIS services; no incoming connections are required. Use trusted networks and avoid open public Wi-Fi.
Use anti-malware protection and a firewall according to the IT policy of your organization.
Back up local DentVIS data regularly — synchronization is not a backup.
Use neutral case labels; the case label also appears in exported file names and can be embossed in the model base.
Open .vis and model files only from trusted sources; store exported files on protected storage and transfer them securely.
Report suspected security incidents or vulnerabilities to the manufacturer without delay (dentmall@email.cz).

Processing of personal data is described in the Privacy Policy.

16. Incident reporting and support

Any serious incident that has occurred in relation to the device must be reported to the manufacturer at dentmall@email.cz (see also the regulatory information page) and to the competent authority of the EU Member State in which the user is established. In the Czech Republic this is SÚKL (State Institute for Drug Control, www.sukl.cz), to which users report serious incidents pursuant to Act No. 375/2022 Coll., on medical devices. The manufacturer reports serious incidents according to Article 87 of Regulation (EU) 2017/745.

For questions and problems that are not incidents, contact the manufacturer at the same address. Please state the software version from About DentVIS, the platform and a description of the problem; do not send identifying personal data.

17. Updates, lifetime and decommissioning

The application checks the version at start. Optional updates are offered with Update available; versions that are no longer supported are blocked with Update required.
A software version is supported until a newer version is required by the manufacturer. Release notes are published with each version.
To stop using the device: export the cases you need as .vis, sign out, uninstall the application (Windows: Apps & features; macOS: move DentVIS to the Bin; iPad: remove the app) and delete local case files and exports according to your data retention rules. Cancelling the subscription is done in the account dashboard.
