Dental splint design software
Design occlusal splints, from scan to STL.
NexorCAD designs the Aubé™ splint from two intraoral scans, in nine steps. Cleanup, blockout, outline and occlusal table are calculated by the software; you check each result and correct it where needed. For dental labs and clinics that already scan and print their splints.
14 days and 75 credits free: three splints. No credit card.

Three products, designed from scan to STL
NexorCAD designs the Aubé™ splint, printable arch models and thermoforming models, and nothing else for now. It is meant for dental labs and clinics that receive intraoral scans and print their splints and models.
Aubé™ splint
A hard, full-arch occlusal splint with a flat occlusal table. The blockout, the outline and the table are calculated; the insertion axis, the retention, the thickness and the landmarks are set by you.
Dental model
The scan trimmed around the teeth and the gum you keep, set on a flat base. Both arches of a case are built in one frame, in occlusion.
Thermoforming model
The arch to thermoform a sheet over, printed as low as it goes. The base follows the gum line and tilts with the teeth, so the collars front and back sit close to it.
Or connect your lab software
Your software can create cases, send the scans and take the finished files back. A model case can be designed as soon as its scans arrive.
What it designs
- A hard, full-arch occlusal splint, upper or lower.
- In centric occlusion, by default: balanced contacts on the canines, a light contact on the incisors and 20 µm of clearance on one supporting cusp per posterior tooth.
- Canine guidance in laterality and anterior guidance on the incisors in protrusion, with no posterior contact in movement.
- A minimum thickness you set, measured from the blockout wax, the surface the splint sits on.
- Undercuts blocked out along the insertion axis, with the retention you set.
- Printable arch models: hollow or solid, on a flat base, articulated on pins for the pair.
- Thermoforming models: as low as they go, the base along the gum line, the walls drafted so the sheet comes off.
What it does not do
- Crowns, bridges, inlays, veneers, dentures and aligners. You can record them on a case, but the software does not design them.
- It does not print. It produces the STL; printing happens on your printer or with whoever prints for you.
- It does not diagnose. The clinician decides whether the splint is indicated and reviews the design.
These limits are listed here so you can judge before you try it.
Time spent on one splint, measured
Designing an occlusal splint is mostly repetitive work: trim the scan, find the plane, block out, draw the border, build the table. NexorCAD calculates those steps; what is left is checking them.
Ten splints a week
Where the numbers come from
Internal measurements: our founder's times on his own cases, from raw scans to STL, after more than 2,000 Aubé™ splints. Generating the splint takes a few seconds of server time, during which there is nothing for you to do. Your first cases will take longer.
One case, start to finish
Every screen below is a capture of the application. This is the whole job on a case.
Step 1 of 9
Load
Create the case by choosing the product and dropping in your intraoral scans, STL or PLY.
- Any intraoral scanner that exports STL or PLY.
- The file is read as it is, with no conversion.
- A case can carry several products.
Step 2 of 9
Clean
Automatic cleanup removes loose fragments and spikes, fills holes and closes the mesh.
- Most cases need nothing more.
- You can touch up an area by hand.
- Cleaning uses no export.
Step 3 of 9
Orient
The occlusal plane is estimated automatically.
- Redefine it with three points: the two first molars and the point between the central incisors.
- Every later step is measured in this frame.
Step 4 of 9
Articulator
The arches are brought into occlusion, onto the bite registration if there is one, with a fit report.
- You set the opening.
- The software records both lateralities and protrusion.
Step 5 of 9
Segment
You paint five zones on the opposing arch: two posterior, two canine and the incisors.
- The engine uses them to place contacts and guidance.
- A rough band per group is enough.
Step 6 of 9
Blockout
Retention areas are shown in blue on the scan.
- The server fills the undercuts with wax along the insertion axis.
- With the retention and draft angle you set.
- You touch it up with the brushes where needed.
Step 7 of 9
Landmarks
You place landmark points on the teeth; the software traces the splint's outline on the wax.
- The outline spans a diastema.
- Move a point or redraw a section before going on.
Step 8 of 9
Generate
The server builds the splint in a few seconds: occlusal table, contacts, guidance and a border on your outline.
- Contacts shown in colour on the splint, with their values.
- A thickness view shows in red any area thinner than the value you chose.
- You touch up where needed.
Step 9 of 9
Finish
The splint is cut against the wax and fitted to the arch with the gap you choose.
- Add a raised or engraved label.
- Export the print-ready STL, at full resolution.
- A printable report for every case.
Cleaning, re-running a step and generating a report use no export. An export is counted when you export the final STL; changes made before that do not use another one. A model case goes through five of these steps: load, clean, orient, generate and finish.See the nine steps
What the software calculates, and what you check
Each step calculates a result and shows it to you. You accept it, correct it with the step's tools, or run the step again.
The same route on every case
Nine steps in a fixed order; each one unlocks the next. Anyone trained on it always knows where a case stands.
Undercut blockout
You set the insertion axis, the retention (a few tenths of a millimetre) and the draft angle. The server calculates the wax in a few seconds; you touch it up with the brushes where needed.
Generated occlusal table
The engine builds the table from the bite, the five zones painted on the opposing arch and the recorded movements. Contacts are shown in colour on the splint, with their values.
Real case
Outline traced from your landmarks
You place landmark points on the teeth; the software traces the outline on the wax and spans a diastema. You can move a point or redraw a section before going on.
Minimum thickness checked
The shell is offset from the blockout wax, not the raw scan. A thickness view shows in red any area thinner than the value you chose.
Nothing to install
The software runs in a recent browser, with no licence per workstation. A test page checks in a few seconds whether your computer is suitable.
Around the designer
The case list and the new case form.
Your cases
Nine dots a row show the step each case reached. You filter, search and pick a case up where it stopped.
New case
A case can carry several products. You pick a product, click the teeth, and the number of export credits is shown as you go.
The case report
Every finished case produces a report: the prescription on a tooth chart, the splint from eight angles, the settings it was built with and the thickness map. Print it for the chart, or send it with the file.
From your lab software
Through the integration API, your software can create cases, send the scans and take the finished files back.
Cases and scans from your software
Create the case, send the upper and lower scans, and take the finished files back when it is done.
Model cases design themselves
A model case can be designed as soon as its scans arrive, each arch as the dental or thermoforming model ordered.
One link into the designer
One link opens any case in the designer, already signed in. It works once, within 15 minutes.

Four things to know before you try it
Your files are yours
Your scans, your cases and the splints designed from them belong to you. You can export everything at any time, including if you stop.
Where 5 to 10 minutes comes from
It is an internal measurement: our founder's time on his own cases, after more than 2,000 Aubé™ splints. Yours will be longer at first.
A young product
The Aubé™ splint and the models are used on real cases. The other products in the catalogue are not designed by the software.
Monthly, cancel anytime
Plans are monthly, in Canadian dollars. You cancel from the app; the plan runs to the end of the month you paid, and your cases and files stay yours.
Before you start
Where does 5 to 10 minutes come from?
It is the time our founder measures on his own cases, from the two raw scans to the STL. The steps that take longest by hand, the blockout, the outline and the occlusal table, are calculated by the software; what is left is checking them. Your first cases will take longer.
What is an Aubé™ splint?
A hard, full-arch occlusal splint with a flat occlusal table. By default in NexorCAD: in centric occlusion, balanced contacts on the canines, a light contact on the incisors and 20 µm of clearance on the posteriors; canine guidance in laterality and anterior guidance on the incisors in protrusion, with no posterior contact in movement.
Is it night guard design software?
For the hard night guard, yes: a full-arch occlusal splint, upper or lower, which is what many night guard prescriptions mean. It does not design soft or dual-laminate guards.
Does it replace my dental CAD software?
No. It designs only the occlusal splint, arch models and thermoforming models. You keep your current software for crowns, bridges and dentures.
Which scanners work?
Any intraoral scanner that exports the upper and lower arches as STL or PLY (iTero, Medit, Primescan and others). The file is read as it is, with no conversion.
Do I need a 3D printer?
No. NexorCAD produces a print-ready STL. You print it yourself or send it to whoever prints for you.
How much does it cost?
Starter is $29 CAD a month with 125 credits (5 splints), Lab $79 with 500 (20 splints) and Pro $149 with 1500 (60 splints), before tax. A splint export is 25 credits and a model 5 an arch. Each credit past the included ones is $0.36, $0.24 or $0.16 on the next invoice: $9, $6 or $4 for one more splint. Credits are spent when you export the final STL; designing, re-running a step and generating a report use nothing. The free trial gives 14 days and 75 credits with no card, and the sample case uses none.
Can my team work in French?
Yes. The application is fully translated, and each person chooses their language.
What happens to my scans?
They stay in your workspace, on our own server in Québec, reachable only by people you invited. A deleted case is purged within 30 days. You can export everything at any time.
Is there a commitment?
No. Plans are monthly: you cancel from the app, the plan runs to the end of the month you paid and nothing is charged after. Your cases and exports stay yours if you stop.
Try it on your own cases
14 days and 75 credits free on your own scans: three splints. The sample case uses none.
No credit card. Creating the account takes about two minutes.
