We herein report the application of a combination of maxillary bone transport and auto-tooth bone grafting for alveolar cleft repair using autogenous extracted teeth developed in Korea.A 9-year-old female patient suffering from unilateral cleft lip and palate was treated with this method. After sagittal interdental right-sided maxillary osteotomy was performed completely between #11 and #12 to the nasal floor, alveolar maxillary bone (#11, 21) was transported in the planned direction and the alveolar cleft was closed. At the end of the transporter activation period, soft tissue in the cleft was removed during so-called "docking surgery" using an electric knife for close bone contact at the docking site. We performed bone transporter removal and simultaneous auto-tooth bone grafting of the patient's supernumerary teeth to the docking site.Maxillary bone transport allowed for simultaneous correction of the nasal septal deviation, maxillary arch deformities, and malocclusion since the dental arch was expanded without donor sacrifice or soft tissue expansion. Auto-tooth bone grafting to the docking site allowed for repair of the bone defects of the nasal floor and alveolar cleft and resulted in a superior bone connection.A combination of maxillary bone transport and auto-tooth bone grafting to the docking site appears to be an effective approach for alveolar cleft repair.
我们在此报告韩国研发的利用自体拔除牙齿进行上颌骨牵张成骨与自体牙骨移植相结合用于牙槽嵴裂修复的应用情况。一名患有单侧唇腭裂的9岁女性患者接受了此治疗方法。在11号牙和12号牙之间完全向鼻底进行矢状牙间右侧上颌骨截骨术后，将牙槽上颌骨（11号牙、21号牙）按计划方向牵张，关闭牙槽嵴裂。在牵张器激活期结束时，在所谓的“对接手术”中使用电刀切除裂隙处的软组织，以便在对接部位实现紧密骨接触。我们拆除牵张器并将患者的多生牙同时自体牙骨移植到对接部位。上颌骨牵张成骨能够同时矫正鼻中隔偏曲、上颌牙弓畸形和错牙合，因为牙弓得以扩展，且无需牺牲供体或进行软组织扩张。对接部位的自体牙骨移植能够修复鼻底和牙槽嵴裂的骨缺损，并实现优质的骨连接。上颌骨牵张成骨与对接部位的自体牙骨移植相结合似乎是牙槽嵴裂修复的一种有效方法。
