Outline of Final Research Achievements

The purpose of this study was to clarify the interrelationships found between maxillofacial soft tissue morphology, occlusal relationships, and oral function in patients with growing unilateral cleft lip and palate. Using 3D digital data, maxillofacial soft tissue morphology was measured and evaluated, occlusal status was classified, and oral functions were evaluated using lip pressure, tongue pressure, and masticatory efficiency, and their interrelationships were evaluated. Results.(1) There was no relationship between age and lip deformity.(2) There was no relationship between age and oral function.(3) No relationship was found between morphology and oral function.
As the reason why no relationship was found between morphology and function, it was suggested that morphological disadvantages may be compensated for by tongue movement and other factors.

Academic Significance and Societal Importance of the Research Achievements

本研究では、片側性唇裂を有する成長期患者を対象とし、顎顔面部での形態と機能の関連性を包括的に明らかにすることを目的とした。これにより、患者全体に共通して認められ問題点や、顎顔面軟組織形態、咬合関係、口腔機能の間に認められる相互の関連性を明らかにする。その結果は、将来的に、より効果的な治療方法、治療タイミング等を決定する一助となると考えられる。
