目的评价金属烤瓷冠桥修复的临床效果。方法对口腔科2007年1月-2009年12月期间115例烤瓷冠桥的临床资料进行了回顾分析。结果经6~36个月随访观察,复查的115例患者中,成功105例,占91.3%;失败10例,占8.7%。在修复失败的病例中烤瓷固定桥失败4例,烤瓷桩核冠失败4例,烤瓷全冠失败2例。在失败的病例中瓷崩裂2例,桩核冠脱落2例,基牙折断1例,基牙并发牙髓炎1例,龈缘红肿1例,食物嵌塞1例,龈缘变色1例,色泽不协调1例。分析失败因素主要有崩瓷,修复体松动脱落,基牙病变,牙龈明显红肿,食物嵌塞,美观因素。结论金属烤瓷冠桥能很好地恢复患者的咀嚼功能,在使用烤瓷熔附金属冠桥修复牙齿缺损及缺失时,应正确选择适应症,合理进行设计,严格规范临床操作程序,才能进一步可提高金属烤瓷冠桥修复的成功率。
Objective To evaluate the clinical effect of metal-ceramic crown-bridge repair. Methods The clinical data of 115 cases of porcelain crowns and crowns bridge from January 2007 to December 2009 were analyzed retrospectively. Results After 6 to 36 months of follow-up, of the 115 patients reviewed, 105 cases were successful (91.3%) and 10 failed (8.7%). In the case of failure to repair the failure of porcelain bridge fixation in 4 cases, failed in 4 cases of porcelain-fused-to-ceramic crown, and failed in 2 cases of failed porcelain crown. In the failed cases, there were 2 cases of porcelain rupture, 2 cases of detachment of coronoid nucleus, 1 case of abutment fracture, 1 case of abutment complicated pulpitis, 1 case of gingival swelling, 1 case of food impaction, 1 case of gingival discoloration, 1 case of uncoordinated color Failure analysis of the main factors collapse porcelain, prosthetic loose off, the abutment lesions, gums obvious swelling, food impaction, aesthetic factors. Conclusion PFM can restore the chewing function of patients well. When using PFM crown bridge to repair dental defects and defects, we should choose the appropriate indications, design rationally and strictly standardize the clinical operation procedures Can improve the success rate of metal porcelain crown bridge repair.
