Mission

We are set out to design a device that will simulate human mandibular motion for purposes of evaluating dental fixtures. To accelerate the experimental process, a need was found for a realistic enviroment in which to test dental fixtures. Our project will focus on simulating motion and force, while maintaining enviromental factors. We are working in conjunction with NIH who will provide us with the critical data which will allow us to build a suitable prototype.

Design of the Mouth Motion Simulator

Our design is based off of an XYZ table design so that data gathered from research on specific XYZ motion can be inputed directly into computer data giving the dental simulator programmable variability. Modifications will be made to the above machine which was donated by Dr. Gomez from the Elecrical Engineering Department. Modifications such as

Mountiong to a solid base - This will give the machine stablility
Replacement of the Z motor - A cam system will be integrated to provide continuous oscilating motion. The new motor will also be upgraded in strength from the old design.
Programming changes - The mechatronic program will be changed to provide contiuous motion of the stepper motors.

Fabrication of the Mouth Motion Simulator

Retrofication of a X-Y-Z motion device
NC machining of components
Purchase of pre-manufactured parts (i.e. motor, bearings...)
Assembly of the components

Testing and Evaluation of the Mouth Motion Simulator

Testing and Evaluation are to be completed soon.
