摘要:

背景:玻璃纤维桩的弹性模量非常接近牙齿结构,所以受力后它能与牙齿成为一个整体共同承受应力而不是相对于牙齿产生作用力,这个特点能有效缓解牙本质的应力集中,有利于防止牙体折裂和其他问题的产生。
目的:分析玻璃纤维材料修复前牙残根残冠的临床效果。
方法:选择桂林市口腔医院门诊96例171颗患牙,行根管治疗后,随机分为3组,分别采用玻璃纤维桩制作复合树脂桩核、铸造钴铬合金桩核、预成金属桩修复前牙残根残冠,其后以钴铬合金烤瓷冠修复,并进行6~24个月的随访观察。
结果与结论:玻璃纤维桩组与钴铬合金组比较,脱落率无显著性意义(P > 0.05),但根折率有明显差异(P < 0.05),相较预成金属桩组的脱落率有显著性意义(P < 0.05)、根折率无明显差异(P > 0.05)。提示玻璃纤维桩修复效果优于金属桩核,临床应用前景良好。

Abstract:

BACKGROUND: The elastic modulus of glass fiber posts is approaching to teeth structure. So it can share the masticatory force with teeth, which can ease the stress concentration of dentinum and prevent from tooth fracture.
OBJECTIVE: To analyze the clinical effects of glass fiber posts on restoration of residual root and residual crown of front teeth.
METHODS: A total of 171 affected teeth from 96 out-patients in Guilin Stomatological Hospital were treated with root canal therapy, and then divided into three groups: restored by glass fiber core and crowns, prefabricated alloy post and crowns, cast alloy post and crowns, respectively. Cobalt-chromium alloy ceramic crown repair was followed. All patients were visited for 6-24 months as follow-up.
RESULTS AND CONCLUSION: The falling rate between glass fiber post group and cobalt-chromium alloy group had no statistical significance (P > 0.05), but root fracture rate had statistical significance (P < 0.05). The falling rate of glass fiber post group and prefabricated alloy post group had statistical significance (P < 0.05), but root fracture rate had no difference (P > 0.05). The restorations of glass fiber posts are superior to metal core and crowns, with good clinical application prospect.
