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 lines and distractor positions. The results of this study showed different expansion patterns, which meant the need for proper approaches in mandibular widening.
