Abstract

Mandibular widening is one method of mandibular distraction osteogenesis, which has anatomic limitations such as curved surface, mandibular condyle and narrow arch. The purpose of this study was to understand the biomechanics of various mandibular widening procedures Experimental models consisted of 6 groups according to different osteotomy hues and distractor positions. The results of this study showed different expansion patterns. which meant the feed for proper approaches in mandibular widening.

하악 이부 확장은 해부학적으로 가동성인 하악골에서 시행하는 견인골 신장술의 한 형태로 곡면화된 표면과 하악 과두, 좁은 치열궁 형태로 많은 제약을 받게 된다. 본 연구는 이러한 한계를 보완하기 위해 적용되는 다양한 형태의 이부 확장을 이해하기 위해 시도되었다 골 절단선의 위치와 견인 장치의 위치를 다르게 하여. 각 8가지 군으로 구분한 후 이부 확장을 시행하였다. 이부 확장은 견인기의 위치와 골 절단선의 형태에 따라 다르게 이루어지는 결과를 얻었다.
