Abstract

Distraction osteogenesis is applied to correct mandible or maxilla deformities. Owing to the distractor being away from the skin, it is not aesthetic. Infection can arise due to manual part. And therefore, it is necessary to make the distractor using a new mechanism. 3D software was used for the intraoral distractor modeling. 3D meshes were used to analyze the stress distribution of the distractor was analyzed using Finite element analysis software. This research developed a intraoral distractor for continuous mandible distraction through convergence study. Base on the results, it provide helpful data for future version of the wireless intraoral distractor in other fields of bio and medical engineering.

악골기형에 따른 외과적 치료방법은 상악골 또는 하악골을 직접 늘리거나 줄이는 방식을 이용한다. 골신장술(distraction osteogenesis)은 열성장한 악골에 치밀뼈절단술(corticotomy)을 시행한 후, 골신장기(jaw bone distractor)를 사용하여 간헐적인 힘을 골에 부과하며 골의 길이를 늘여주는 대표적인 방법이다. 그러나 이러한 골신장기는 피부를 관통한 채 골에 고정되기 때문에, 비심미적이며 감염이나 흉터 등의 많은 문제점이 발생한다. 이 연구에서는 구내형 골신장기(intraoral jaw bone distractor) 개발을 위해 유한요소분석을 시행하여 핵심구동부의 안정성을 시뮬레이션한 후, 골신장기를 제작하였다. 융합연구를 통하여 향후 무선형 골신장기를 제작하기 위한 기반 자료를 구축하였으며, 관련 자료는 골신장술의 근본적인 문제점을 해결할 수 있는 가능성을 제시하며, 제반 기술은 다양한 의료기기 개발 기술에 활용될 수 있다
