利用成品钛合金螺纹桩对后牙残根烤瓷修复的疗效观察

Effects of porcelain Fused to Metal(PFM) Prosthesis by finished product Titanium Alloys screw post core for the residual dental roots of posterior teeth

目的为探讨后牙残根利用成品螺纹桩经烤瓷修复后的疗效。方法随机选择后牙残根128例,经完善根管治疗,牙齿无松动,牙根超过8mm,经半月观察,临床无自觉症状,利用成品钛合金螺纹桩进行烤瓷修复。结果经1年到3年复查,成功率(120例)93.8%,失败率(8例)6.2%,临床疗效满意。结论后牙残根经完善根管治纹桩烤瓷修复,可以保留患牙,恢复咀嚼功能及美观的要求。

Objective To explore the effects of PFM prosthesis by finished product screw post core for the residual dental roots of posterior teeth. Method Chose 128 residual dental roots of posterior teeth randomly which have more than 8 mm length. To observe ha/f of one day after consummate root canal therapy, if they haven＇t self-conscious symptom in clinical, then using finished product Titanium alloys screw post core to have Prosthesis. Results We got the satisfaction effects in clinical when we rechecked after 1 to 3 years. The succeed rate was 93.8% （ 120 samples） and the failure rate was 6. 2% （ 8 samples）. Conclusion The residual dental roots of posterior teeth can be reserved after consummate root eannal therapy and PFM Prosthesis by finished product screw post core, we also can recover their chewing function and get purpose to regain their beautiful.
