预成纤维桩在口腔修复中的临床效果评价

目的：探讨预成纤维桩在口腔修复中的临床效果。方法：将2012年8月至2012年11月来我科就诊的100例口腔修复患者按照抽签法随机地均分为对照组与观察组，均为50颗患牙。对照组给予铸造金属桩口腔修复，观察组给予预成纤维桩口腔修复，比较两组疗效、满意度、平均每颗纤维桩所需时间及牙周指数变化。结果：经半年的随访，对照组修复成功率为80．00％（40／50），明显小于观察组（100．00％，50／50），两组相比，差异具有统计学意义（P〈0．05）；对照组满意度为60．00％，明显小于观察组（92．00％），两组相比，差异具有显著的统计学意义（P〈0．01）；对照组平均每颗纤维桩所需时间为（102．22±22．09）min，观察组为（66．37±11．78）min，两组相比，差异具有统计学意义（P〈0．05）；两组术前牙周指数（BI、PLI、PD及松动度）差异均无统计学意义（P〉0．05），但术后2周、3个月、6个月两组牙周指数差异均具有统计学意义（P〈0．05，P〈0．01）。结论：顸成纤维桩应用于口腔修复中，效果尤佳，患者满意度高，美观效果好，值得在临床上加以推广并应用。

Clinical Evaluation of Pre-fiber Post in Prosthodontics

Objective： To investigate the pre-clinical effect of fiber posts in prosthodontics. Methods： 100 cases of patients with mouth rehabilitation in our department between August 2012 and November 2012 were randomly divided into a control group and an observation group according to the law of the draw, and each group had 50 ill teeth. The control group were given the cast metal post oral restoration, while the observation group were given pre-fiber pile oral repair. The two groups were compared in aspects of satisfaction, the required average time for fiber post and periodontal index changes. Results： After a half year of follow-up, the control group had a re- pair success rate of 80.00% （40/50）, and was significantly less than that of the observation group （100.00%, 50/50）, and the difference was statistically significant between the two groups （P〈0.05）. The satisfaction of the control group was 60.00%, and was significantly less than that of the observation group （92.00%）, and the difference was also statistically significant between the two groups （P〈0.01）. The av- erage time required for each fiber post was （102.22 ＋ 22.09） min in the control group, but was （66.37＋ 11.78） rain in observation group, and there was statistically significant difference between two groups （P〈0.05）. There was no significant difference before operation in preoperative periodontal index （BI, PLI, PD and loose degrees）（P〉0.05）, but at two weeks, three months, six months after operation, there were statistically significant differences in periodontal index between the two groups （P〈0.05, P〈0.01）. Conclusion： Pre-fiber posts used in prosthodontics had advantages, such as best effect, high patient satisfaction and a beautiful look, thus it is worth of being promoted and applied in the clinic.
