不同桩核修复上颌前牙残根残冠的疗效比较

目的:对比玻璃纤维桩树脂核与铸造金属桩核修复上颌前牙残根残冠的疗效。方法:选取2011年10月至2013年12月在我院口腔科就诊的120例因前牙牙体缺损或者冠折需行桩核冠修复术的患者,随机分为玻璃纤维桩组及铸造金属桩组,每组各60例。玻璃纤维桩组采取玻璃纤维桩核与烤瓷全冠修复术治疗,铸造金属桩组采取钴铬合金铸造桩核与烤瓷全冠修复术治疗。对比2组患者修复治疗的疗效及失败情况。结果:玻璃纤维桩组有1例(1颗)患者因搬迁失访,铸造金属桩组有2例(2颗)患者因金属致敏性导致治疗中断;余117例(179颗)患者中,玻璃纤维桩组共92颗牙,成功率为89.13%,铸造金属桩组共87颗牙,成功率为79.31%,玻璃纤维桩组的明显高于铸造金属桩组;玻璃纤维桩组牙根折裂、桩核松动或脱落的发生率明显低于铸造金属桩组;而桩核折的发生率则明显高于铸造金属桩组,差异有统计学意义(P0.05)。结论:玻璃纤维桩具有美观、抗疲劳、易于操作、患者复诊次数少等优势,且不存在细胞毒性及过敏反应等问题,其修复效果优于铸造金属桩核。

Effect Comparison of Different Post and Core in the Repair of Residual Root and Crown of Maxillary Anterior Teeth

Objective:To compare and analyze the clinical effects of the two different repairment on the residual root and crown of maxillary anterior teeth.Methods:120 cases of patients with anterior teeth defect or crown fracture who needed surgery to repair the line core crown pile from October 2011 to December 2013 in our hospital were randomly divided into glass fiber pile group and cast metal pile group, each with 60 cases. Glass fiber pile group were given nuclear and porcelain crown treatment. Cast metal pile group were given chromium alloy cast post and core drilling with a porcelain crown treatment, restorative treatment efficacy and failures of two groups were compared.Results:Glass fiber pile group had 1 case due to the relocation lost to follow-up, follow-cast metal pile group had 2 cases patients of treatment interruption due to metal sensitization, which were removed. In the rest 117 cases (179 tooth) of patients, the glass fiber pile group had 92 teeth, the success rate was 89.13 %, cast metal pile group had 87 teeth, and the success rate was 79.31%, significantly higher than the fiberglass cast metal pile group; glass fiber pile group root fracture, the incidence of post-core loose or fall off was significantly lower than that of cast metal pile group; while the incidence of nuclear pile off the pile group was significantly higher than that of cast metal pile group. The difference was statistically significant (P <0.05).Conclusion:Glass fiber post is beautiful, fatigue, easy to operate, results in fewer patient referral and there is no cell toxicity and allergic reactions or other complications, the repair is better than that of metal post.
