Clinical application of mandibular distraction osteogenesis
摘要
Abstract
Distraction osteogenesis(DO)is a surgical technique that promotes new bone formation by gradually pulling apart bone segments using a specialized distraction device.Initially developed for orthopedic surgery,DO was introduced into craniofacial surgery in the 1990s and has since been widely applied in the treatment of mandibular hypoplasia and jaw defect reconstruction.This paper reviews the fundamental principles,technical aspects,indications,advantages,and disadvantages of mandibular distraction osteogenesis,and discusses different distraction modes,including unifocal,bifocal,and trifocal distraction.The advantages of DO include the avoidance of bone grafting,minimal surgical trauma,and simultaneous soft tissue expansion.However,its long treatment duration and associated complications remain challenges for broader clinical application.In the future,the integration of imaging navigation and artificial intelligence is expected to enhance surgical precision and treatment stability.关键词
