摘　　要：目的：评价微创粘结法保存冠根联合折裂牙的疗效。方法：选择后牙冠根联合折裂患者94例,折裂方向为斜折,折裂位置在龈下4-7 mm。对未经根管治疗的患牙,在钢丝结扎固定下,行一次性根管治疗术,拆除结扎丝后行牙龈剥离;已行完善根管治疗的患牙,直接行牙龈剥离;然后拔出松动折裂片,并处理折裂面;采用Super-Bond C＆B粘结剂行断面粘结,龈瓣复位,降牙合,结扎丝再次结扎;术后2周拆除结扎丝行全冠修复。结果：94例斜折牙治疗后满6个月及1、2、3年随访,患牙保存率（%）分别为：100.00、98.82、91.84、86.67。结论：微创粘结法保存折裂至龈下4-7 mm的冠根联合斜折牙有效可行,具有较高的患牙保存率。AIM： To evaluate the therapeutic results of minimally invasive bonding over the teeth with oblique crown-root fracture. METHODS： 94 cases of the teeth with oblique fracture under 4- 7 mm of subgingival margin were treated with perfect root canal therapy after outer steel wire ligation,followed by gingival stripping,fragments extraction and granulation tissue cleaning. And then the fractured fragments were cemented with anacrylic resin cement（ Super-Bond CB）,fluid resin infilling,and finally,completed coronal restoration. The cases were followed up for 6months,1,2 and 3 years. RESULTS： The teeth preserve rates were 100. 00%,98. 82%,91. 84% and 86. 67% respectively at 6 m,1 y,2 y and 3 y of follow-up. CONCLUSION： Minimally invasive treatment is effective to save the teeth with oblique crown-root fracture under 4- 7 mm of subgingival margin.
