| Outline of Final Research Achievements |
The profile of mastication dominance and ability of mastication before and after prosthodontic treatments was investigated in 22 patients with missing posterior teeth and 14 patients with maxillofacial defects. Nineteen healthy dentate individuals were used for controls. Data was obtained for the status of occlusion, stomatognathic function, and masticatory function including the subjective satisfaction/disability of chewing and oral health related quality of life using questionnaire. Mastication dominance was determined by the deviation of electromyographic activities obtained from bilateral masseter muscles. The obtained results revealed that the profile of mastication dominance of patients with maxillofacial defects did not improved as that for patients with missing posterior teeth.

| Academic Significance and Societal Importance of the Research Achievements |
顎欠損患者に対する補綴歯科治療（顎顔面補綴治療）による偏咀嚼の改善の様相、偏咀嚼の改善度と咀嚼能力の改善度との関係、咀嚼しやすさの自覚、咬合力、咬合接触、咀嚼能率などの主観的および客観的な咀嚼能力との関連を明らかにすることにより、補綴治療による咀嚼機能の改善度のより正確な予測が可能である。これにより、歯科治療開始前のインフォームドコンセント、アカウンタビリティーの向上に寄与すると考えられる。また、本研究の成果は、補綴治療に関する「臨床ガイドライン」の策定にも寄与すると考えられる。
