Onlay植骨治疗牙槽嵴裂植骨术后成骨不良的初步研究

Treatment Research of Bone Defect after Alveolar Cleft Graft by Means of onlay Bone Graft

目的:采用onlay植骨的方法对于牙槽嵴裂植骨术后成骨不良的患者进行再植骨治疗,并进行疗效评价。方法:将在笔者医院口腔颌面外科住院手术治疗的10例牙槽嵴裂植骨术后成骨不良患者作为研究对象,采用onlay植骨的方法对上述患者进行二次植骨,并于术后1月和术后半年对二次植骨效果进行评价。结果:该组研究对象经onlay植骨手术后手术切口均一期愈合。通过比较术前和术后CBCT检查结果,可以发现裂隙区成骨高度和成骨厚度均有改善,经统计学分析有显著性差异(P<0.05)。而术后半年与术后1个月两个时间点成骨效果比较无统计学差异(P>0.05)。结论:Onlay植骨法应用于治疗牙槽嵴裂植骨术后成骨不良,疗效确切。

Objective Adopting the method of onlay graft for alveolar cleft graft treatment, postoperative patients with osteogenesis bad were replantated with bone ,then evaluated the curative effect. Methods In oral and maxillofacial surgery in our hospital surgical treatment of alveolar cleft graft 10 patients with bone defect after alveolar cleft graft were selected as the research object, and the method of onlay bone graft was adopted for the patients with secondary bone graft, then evaluated theeffect of secondary bone graft at 1 month after operation and six months after operation. Results This group of patients by the onlay bone graft surgery incision were primary healing. By comparing the preoperative and postoperative CBCT results,could be found that the fracture zone osteogenesis could improve the height and thickness of the ossification, through statistic alanalysis of the statistical differences (P <0.05). After half a year and postoperative 1 month osteogenesis effect was no statistical difference (P >0.05). Conclusion Onlay bone graft method applied in the treatment of alveolar cleft graft surgery osteogenesis,its curative effect was accurate.
