Main Research Interests
Physiology of the masticatory system
The human masticatory system includes teeth, periodontal structures, jaw and alveolar bones , musculature of head and neck, and the neural complex. The physiology of this system includes chewing, swallowing and phonation.The roles of this syrstem on the physiologic functions are observed via the use of electromyography, bite force transducers, and jaw motion tracking devices (optoelectric and magne-toelectric devices) for a better understanding of the masticatory function. Some computer CAD/CAM system is used to observe the three dimensional occlusal form. For the observation of muscle size and orientation, MRI system and self developed reconstruction and measurement softwares are also applied. Ultrasound detection of the muscle size is another alternative.For the observation of biting force and chewing efficiency, standardized testfoods of known hardness were developed and applied. Further improvement on the hardness, edibility and water solubility will be improved in future studies.
Temporomandibular joint and muscle pain dysfunction
Some temporomandibular joint diseases or non-pathological morphological and positional changes may cause pain and dysfunction of the masticatory system. Some muscle tension, fatigue and tense may also cause pain and dysfunction of the jaw. We have been working with the prevalence, etiology, symptomatology and functional analysis of the disorders of the system (TMD). Recent studies are related more on the diagnostic modality and the evaluation of functional disturbances. Clinical and laboratory examinations including image analysis and its validity and sensitivity are emphasized
Clinical studies on prosthetic dentistry
In addition to the studies on the post-prosthetic jaw movement and muscle function related bite force and dental occlusion, dental implant and magnetic attachment are also studied. The design and use of the magnetic attachment on pulpless tooth and implant abutment are undergoing with the collaboration of Aichi Steel Co in Japan. New magnet attachments will be developed and manufactured for dental clinical use. The design of magnet attachment on abutment of dental implant will be the main target of magnet studies in our department.
