目的观察应用医用带光源头戴式放大镜行后牙区嵌体、冠及桥修复的临床效果。方法从2010年1月至2010年6月就诊需要行后牙嵌体、冠、桥修复的患者中随机选取100例,其中嵌体43颗,冠33颗,桥24例(3个单位桥17例,4个单位桥7例),应用医用带光源头戴式放大镜辅助下备牙。精确取模后戴牙时也在医用带光源头戴式放大镜辅助下行粘结剂清理。患者每半年复诊,评价修复体完整性、边缘密合性及牙龈指数,连续观察2次。结果利用医用带光源头戴式放大镜行后牙区的嵌体、冠、桥修复在半年及一年后在修复体完整性、边缘密合度及牙龈指数等方面令人满意。结论应用医带光源头戴式放大镜行后牙区嵌体、冠、桥修复值得临床推广。
Objective To observe the clinical effect of using medical magnifier with light source in posterior teeth intima, crown and bridge repair. Methods From January 2010 to June 2010, 100 patients were enrolled in this study. Among them, 43 were inlay, 33 in crown and 24 in bridge (3 units of bridge 17 Case, 4 unit bridge in 7 cases), the application of medical light source with a magnifying glass with aided backup teeth. Accurately modeled wearing the teeth is also in the medical light source with a magnifying glass to help downstream adhesive cleaning. Patients were reviewed every six months to evaluate the integrity, marginal adhesion and gingival index of the prosthesis. The patients were continuously observed twice. Results The use of a medical magnifying glass with a light source in the posterior teeth area of the inlay, crown, bridge repair in six months and one year in the restoration of completeness, edge adhesion and gingival index and so satisfactory. Conclusion The application of medical light source wearing magnifying glass in posterior teeth intima, crown, bridge repair worthy of clinical promotion.
