Outline of Final Research Achievements

Using the occlusal splint for the sleep bruxism monitoring device, it was possible to evaluate grinding area and grinding pattern, and make the proper treatment plan for each patient. But, there was no association between the electromyographic activities of the masseter muscle during sleep and the abraded areas of the occlusal splint. However it was not able to decide the thickness and wearing period of the occlusal splint device which was suitable for the evaluation of the abrasion area of the splint.
It was easy for a patient and a dental technician to understand an abrasion range of the sprint and a burden of the abutment teeth using the evaluation result on the abrasion range of the device when explaining the design of the prosthodontic treatment for a patient.
