| 摘 要： | 目的 观察铸造金合金核桩冠和玻璃纤维核桩冠修复前牙残冠残根的临床效果。方法 选取72例(18~52岁)前牙残冠残根患者,共计120颗患牙,经过完善的根管治疗后随机分为2组:A组60颗患牙,使用铸造金合金核桩冠;B组60颗患牙,使用玻璃纤维核桩冠;同时每一组又分为有牙本质肩领组和无牙本质肩领组。全部患牙均用贵金属烤瓷全冠恢复牙体外形。观察2组患者的修复成功率。结果 随访24个月后,铸造金合金核桩冠组和玻璃纤维核桩冠组修复成功率相似,但在有牙本质肩领和无牙本质肩领时铸造金合金核桩冠组和玻璃纤维核桩冠组修复成功率相差较大。结论 牙体组织残留量及所选核桩材料与修复成功率密切相关。?

| Abstract: | Objective To evaluate the clinical effects of cast gold alloy post and glass fiber-reinforced post applied in the restoration of anterior residual crown and root.Methods 120 residual crowns and roots of anterior teeth from 72 patients,aged from 18 to 52 years,were included in the study.Among the 120 teeth,60 teeth in the A group were restored with cast gold alloy post,while the other 60 teeth in the B group were restored with glass fiber-reinforced post.At the same time,each group was divided into a dentin ferrule group and a non-dentin ferrule group.All the teeth were then restored with porcelain fused metal crown.The esthetical property and the survival rate of the prostheses were observed.The data were analyzed with statistical test.Results The prostheses were followed up in this clinical study for a period of 24 months.The cast gold alloy post group and the glass fiber-reinforced post group of the survival rate were not significantly different.But,among the dentin ferrule group and the non-dentin ferrule group,the survival rates between the cast gold alloy post group and the glass fiber-reinforced post group were statistically significant.Conclusion The selection of the post core material is closely associated with the sucess rate of tooth restoration. |
