Stomatognathic Function and Occlusal Reconstruction

Main research and clinical subjects of the department of stomatognathic function and occlusal reconstruction are the restoration and maintenance of occlusion and the jaw function. We also have education course of fixed prosthodontics (crown and bridge) for undergraduate students of the dental school.

Education

  • Undergraduate
    • Fixed Prosthodontics
      Lecture, laboratory and clinical training The objective of this clinical training course is to learn basic procedures of Fixed Prosthodontics treatment through experience.
      The laboratory work for porcelain restorations is placed an order outside professions. But students have to make prosthetic products with their patient’s working model as a basic training after finishing their cases.
    • Maxillofacial Prosthodontics
      Lecture and observation study
    • Dental Implant
      Lecture and observation study
    • Dental Metal Allergy
      Lecture and observation study
    • Obstructive Sleep Apnea Syndrome
      Lecture

     

  • Postgraduate
    Postgraduate students take part in researches about occlusion and jaw functions. Development of a new six-degrees-of-freedom jaw tracking device is one of the main technical subjects in our researches. As skill of computer programming technique is essential to conduct the study of jaw function analysis, students are trained in computer technology. Students also take instructions for making scientific presentations and research theses.

 

Research Projects

Overall object of our research projects is to clarify the relationship among occlusion, jaw movement and stomathognathic function. For this purpose, we developed the digital jaw movement analyzing system, extremely accurate six-degrees-of–freedom jaw tracing device, in this research project. This technology made it possible to analyze dynamic transition of occlusal contacts and inter joint space during mastication and other jaw functions, by combining 3-D digitized data of dentition, reconstructed temporomandibular joint images and six-degrees-of freedom jaw movement data. The jaw function diagnosis system with this device was authorized by the Ministry of Welfare as a Specially Approved Insurance Medical Care Facility for “Prosthetic treatment for temporomandibular disorders”. This system has been utilized for TMD diagnosis in the clinic since August 1, 1992.
Recently, our department has carried out a development of a new miniature six-degrees-of–freedom jaw tracing device utilizing small magnetic sensor coils. We expect that this new device will be applied for the study of occlusal contacts during sleep associated bruxism as well as for other research projects.
