摘要
目的:探讨牵张成骨技术治疗火器伤牙槽突缺损的临床应用。方法:2例患者分别因火枪和炸药爆炸导致下颌骨牙槽突缺损,一期经清创处理,遗留严重牙槽突缺损,影响义齿修复,接受牵张成骨治疗,其中1例行垂直骨牵张,另1例接受水平骨牵张。结果:2例患者均顺利完成治疗,垂直骨牵张升高牙槽突约7mm,水平骨牵张牙槽突恢复长度约16mm,X线显示成骨良好。结论:牵张成骨技术可以有效地修复火器伤牙槽突缺损,并为最终重建咬合关系和实现功能性修复提供了基础,为火器伤的救治提供了一条新的修复方法,值得临床借鉴和推广。
Objective To investigate the clinical application of distraction osteogenesis techniques in alveolar defects wounded by firearm. Methods Serious alveolar defects were remained in 2 patients wounded by firearm after first- stage debridement, causing increasing difficulty in denture.Distraction osteogenesis techniques were used for the solution with horizontal distraction in one case and vertical distraction in the other. Results The two patients were performed as planned. The amounts of distraction were 7mm in horizontal distraction, and 16mm in the vertical distraction. All the territories showed good new bone by X-ray examination. Conclusion Distraction osteogenesis was an effective method for the repair of alveolar defects wounded by firearm,which sets a foundation for further occlusal reconstruction and functional repair. This technique provides a new approach for the treatment of alveolar defects wounded by firearm and is good for popularize.
