About Us

Originally cleared by the FDA in 2000, the NTI devices and therapeutic protocol were developed by James P. Boyd, DDS.  NTI devices are marketed worldwide through ChairsideSplintStore.com  by Boyd Research, Inc. 

Also joining the family of NTI devices is the new BruxSplint, for the asymptomatic bruxing patient.

Dentists who would like to discuss and interact with Dr. Boyd and other NTI providers are encouraged to log on to DentalTown and participate in the TMD & Occlusion discussions on the Message Boards.


AMPSA CS ® is a registered trademark of Therapeutic Solutions International, Inc., a product whose technology has been licensed from Boyd Research. It is the exact same as the NTI-tss® device and derived from the same patent.
