Development of a 3D Printed Teeth Splint with a colorimetric sensor for Bruxism Diagnosis

Problems of Sleep Bruxism

Sleep bruxism(SB) is a stereotyped movement disorder characterized by grinding or clenching of the teeth during sleep.
Approximately 10% of the population have a bruxism which is a movement disorder of a masticatory system.
In the long term, SB can lead to teeth wear, temporomandibular disorders, and headaches.

Current Limitations of Diagnostic Method of Bruxism

Traditional diagnosis methods like questionnaires cannot explain exactly how severe bruxism is so our goal is to develop an instructive, and simple method to diagnose Bruxism.

Proposed Solution

Modeling the teeth and split by SolidWorks and Meshmixer
- Four layers with different colors
- The thickness for each layer is 0.5 mm (minimum thickness to distinguish the color)
A tooth model will be used for the wear test with a chewing simulator with following conditions
- Normal forces are 50 and 90N
- The number of cycles are 20,000 and 40,000
