摘要
目的从生物力学角度探究玻璃纤维桩在上颌前磨牙根管治疗的疗效。方法将我院97例上颌前磨牙牙体缺损、残根残冠的患者需修补的132例牙齿进行分组,对照组65颗磨牙残冠采用传统的银汞合金充填加金属烤瓷全冠修复,实验组67颗磨牙残冠经完善的根管治疗后,采用玻璃纤维桩进行烤瓷冠修复,对两组患牙进行随访调查,按标准统计治疗成功例数,并通过样本试件进行负荷试验,比较两种不同修复方式修复牙齿的抗折能力。结果经玻璃纤维桩修复的实验组治疗成功率(94.03%)远高于采用传统方式修复的对照组(75.38%),比较结果有统计学意义;实验组的抗折能力明显高于对照组,经统计学分析有意义。结论玻璃纤维桩在上颌前磨牙根管治疗后的生物力学性能优于传统的合金充填与金属烤瓷修复,适合临床使用。
Objective To study glass fiber-reinforced post＇s curative effect on jaw premolar root canal treatment from the point of biomechanics. Methods Chosed 97 cases of those jaw former mill fang body defect and residual root and crown patients 132 cases of teeth which needed repairing,and divided these teeth into control group and experimental group, adopted conventional silver amalgam filling and metal PFM full crown to repair 65 cases of those molar residual crowns teeth in control group, while after proceeded perfect root canal therapy to experimental group＇s 67 cases of teeth, adopted glass fiber-reinforced post for PFM crown restoration, proceeded follow-up investigation to these two group＇s offending teeth, calculate successful number according to standard, what＇s more,proceeded stress test through sample test-piece, compared these teeth＇s fiexural capacity after they have been repaired by different methods. Results Experimental group＇s treatment successful rate was （94.03%）, it was far higher than control group＇s （75.38%）, the comparison result has statistics meaning; Experimental group＇s flexural capacity was obviously higher than control group＇s, it has meaning through statisti- cally analysis. Conclusion Glass fiber-reinforced post＇s biomeehanieal property after jaw premolar root canal therapy is better than the traditional alloy filling and metal PFM restoration＇sAt suits clinical use.
