Aubé™ splint

The Aubé™ splint, designed in nine steps

A hard, full-arch occlusal splint with a flat occlusal table, from two intraoral scans. Each step calculates its result and shows it to you; you check it, correct it where needed, and export a print-ready STL.

How it works, step by step

For each step: what the software calculates, what you set, and what goes on to the next step.

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.

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.

The In the bite section of the NexorCAD case report: the finished upper splint with the jaw closed onto it at its designed opening, and the other bite views below.

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 designer at the Generate step: the nine steps across the top, all checked, and the generated splint on the lower arch

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.

The Blockout step: the insertion axis, a retention of 0.09 mm and a draft of 2°, beside the lower arch and its blockout wax

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.

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.

The Generate panel with the thinnest allowed set to 2.0 mm, beside the splint

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.

The browser check page saying this computer is ready, with its 3D test running

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.

What you gain

Less time at the screen

For ten splints a week, about 9 hours in installed software becomes about 1 h 15, at the middle of each range.

A balanced splint by default

Balanced contacts on the canines, a light contact on the incisors, 20 µm on the posteriors, canine guidance in laterality and anterior guidance in protrusion.

Fewer touch-ups

In our founder's experience on more than 2,000 Aubé™ splints, the generated table needs fewer touch-ups than the splints he designed by hand. One person's experience, not a study.

The same route for everyone

Nine steps in a fixed order; anyone trained on it knows where a case stands, and any step can be run again.

The times are our founder's own, on his own cases, after more than 2,000 Aubé™ splints. Yours will be longer at first.

Questions

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.
