玻璃纤维桩树脂核全瓷冠在前牙残冠及残根修复中的临床应用价值探讨

Observation on clinical application value of all-ceramic crown of glass fiber post and resin core for residual crown and residual root repair of anterior teeth

目的探讨在前牙残冠、残根修复中使用玻璃纤维桩树脂核与全瓷冠的临床应用效果及价值。方法选取本院2010年4月至2012年3月收治的前牙残冠、残根患者106例,根管治疗后修复,并根据修复方式分为观察组与对照组,观察组患者使用玻璃纤维桩树脂核与全瓷冠修复,对照组患者使用铸造金属桩核与烤瓷冠或全瓷冠修复,对比观察两组修复效果。结果随访2年后,观察组患者修复成功率与满意度明显高于对照组,修复体脱落率与桩折率明显低于对照组(P<0.05),差异具有显著性。结论在前牙残冠、残根修复中使用玻璃纤维桩树脂核与全瓷冠,固位良好,颜色与外观维持良好,对周围组织刺激较小,能够有效减少修复体的脱落与折断,明显提高修复成功率以及患者对修复体的满意程度,具有理想的临床应用价值。

Objective To observe the clinical application value and effect of all-ceramic crown of glass fiber post and resin core for residual crown and residual root repair of anterior teeth. Method 106 cases with residual crown and residual root of anterior teeth treated in our hospital from April 2010 to March 2012 were selected, and the patients received repair after root canal therapy. The patients were divided into two groups according to repair modes, observation group and control group. Observation group received repair of all-ceramic crown of glass fiber post and resin core, and control group received repair of cast metal postcore and baked porcelain crown. The repair effect of two groups was compared and observed. Result After following up for two years, the success rate and satisfactory degree of observation group was evidently higher than that of control group, and the expulsion rate and odontagma rate of restoration was lower than that of control group （P 〈 0.05）, which had statical significance. Conclusion Applying all-ceramic crown of glass fiber post and resin core to all-ceramic crown of glass fiber post and resin core for residual crown and residual root repair of anterior teeth not only has good retention, good color and appearance maintenance, and has little stimulation on the surrounding tissues, but also can effectively reduce detachment and fracture of restoration, which evidently improves the success rate of repair and satisfactory degree of patients, which has ideal clinical application value.
