摘　　要：目的:分析根尖切除术不同骨缺损范围单纯覆盖口腔修复膜的疗效。方法:选取20例患者的28颗患牙的根尖切除术病例,术中单纯以口腔修复膜覆盖骨缺损区域,测量患牙术前及术后6个月数字根尖片的根尖周暗影范围,结合临床表现分析病损愈合情况。根据28颗患牙术前根尖暗影最大直径范围(x)分4组:x<4 mm,4 mm≤x<6 mm,6 mm≤x<8 mm,x≥8 mm。结果:以临床症状消失,或影像学表现根尖周透射区范围缩小或消失视为成功,19例患者、26颗患牙治疗成功;其中失败的1例2颗患牙属于x≥8 mm组,临床表现为仍有叩诊不适,扪诊不适,X线片示根尖阴影未缩小。结论:根尖暗影范围小于8 mm的病例进行根尖切除术时,骨缺损区单纯覆盖口腔修复膜可获得较好的临床疗效。Objective:To analyze the effect of covering oral prosthesis membrane in apical resection of different bone defect areas.Methods:The shadow of digital periapical radiographs of 20 patients with bone defect covered by oral restorative membrane during apicectomy were measured before and 6 months after operation,and the healing of the lesions was analyzed combined with clinical manifestations.According to the diameter range(x)of the apical shadow of the 28 teeth before operation,they are divided into 4 groups:x<4 mm,4 mm≤x<6 mm,6 mm≤x<8 mm,x≥8 mm.Results:The disappearance of clinical symptoms or imaging manifestations of reduction or disappearance of the periapical transmission area was regarded as success.19 patients and 26 teeth were successfully treated.Among them,the failure of 1 case and 2 teeth belonged to the fourth group.The clinical manifestations were as follows:There is still discomfort on percussion,and discomfort on palpation.X-ray film shows that the shadow of the root tip has not been reduced.Conclusion:In the case of apical shadow less than 8 mm,it is better to cover the defect area with prosthodontic membrane.
