摘要
目的比较石英纤维桩和玻璃纤维桩与金属烤瓷全冠(PFM)修复后牙残根、残冠的临床效果.方法选取120例(20～58岁)患者,197颗后牙残根、残冠,经过完善的根管治疗后,随机分为2组,A组60例患者共96颗患牙,采用石英纤维桩和PFM修复;B组60例患者共101颗患牙,采用玻璃纤维桩和PFM修复.随访24个月,观察2组患者的修复效果,并用SPSS软件包对2组修复体的成功率进行χ2检验.结果 2组修复体成功率的差异无统计学意义(P>0.05),但是在抗桩核折断这一项上差异有统计学意义(P<0.05).结论石英纤维桩与玻璃纤维桩对后牙缺损均能取得良好的修复效果,石英纤维桩在临床上的抗桩核折断性能更优于玻璃纤维桩.
Objective To compare the clinical effects of the quartz fiber post and glass fiber post in the restoration of residual crown and root.Methods 120 patients with 197 residual crown and root of posterior teeth,aged from 20 to 58 years,were included in the study.They were divided into two groups randomly after perfect root canal therapy.96 teeth in the A group were restored with quartz fiber post core and PFM,while 101 teeth of the B group were restored with glass fiber post core and PFM.The restoration effects were observed during consecutive 24 months and the data was analyzed with SPSS software package for test.Results The difference of the success rate between two groups was statistically insignificant（P〉0.05）,but the difference of post and core fracture resistance was statistically significant（P〈0.05）.Conclusions The quartz fiber post and glass fiber post both can be used as an ideal restoration material for posterior tooth defect.The post and core fracture resistance of the quartz fiber post is better than glass fiber post.
