Adjustable Dental Trainer
This is the prototyping journey I went on for my Senior Design class. We decided on an adjustable dental trainer that offers a range from normal to abnormal morphologies. The goal is to continue innovations in the upcoming semester to create a proper mannequin training device.
Early Prototype
This mainly held our early prototype. It seemed that an old deconstructed crutch could be used for fast prototyping.
Neck Adjustment
Laser cut trials for how to adjust the neck and jaw length and width.
Formlabs SLA resin
I received files of crowded teeth and printed them out after testing multiple materials and doing test patches with paint. This material will be moved forward with for the final teeth whereas the gums will be silicone. On the right the gums are painted
Dragonskin 30 Silicone
This will be the materials used for the final gums moving forward. It offers a decent texture.
Skull
I scanned a human skull prior to making slices in fusion and printing in 3 parts. I then connected magnets and a track to allow for variable size and connection to the articulator which I fastened with magnets.
Articulator Connection
This is how the "Jaw" was connected to the skull cap with the tracks.
Final Snapshot
Currently this is where we bid this chapter goodbye. Until next Semester!
Current Trainer
This is a current Dental Trainer before being gutted and edited for our purposes.
Fitting current schools
Trimmed and fitted for universal use.
Track for bite adjustment
Track is added to articulator for under and overbite. Later Crossbite is added. Articulator taken apart to give movement wanted and keep functionality.

Trimming the bar for bite adjustment.
Current fit
The model slides together nicely and simulates more situations than initially expected.

Dental trainer was tested at the local Dental school skills lab was a success. The attachment component held strong through final rounds of testing for mannequin to current dental school chair compatibility.
