摘要
目的 比较 3种类型桩钉作桩核冠修复体的远期疗效。 方法 对笔者 1996年 7月 2 0 0 2年 6月在门诊所做的 4 86例 6 14件修复体的临床资料进行分析。 结果 残冠组不同桩钉修复体的远期疗效差异无显著性 (P <0 .0 5 ) ;残根组用自制桩钉的修复体与用预成螺纹桩和铸造桩的修复体远期疗效差异有显著性 (P <0 .0 5 )。两组总成功率为 85 .0 %。失败的主要原因为桩松脱 ,其次为基牙病变。 结论 为提高桩核冠修复体的远期疗效 ,应在桩的选择和设计。
Objective To compare the long term effectiveness of three types of dowel pin as treatment post core crowning. Methods The date of 614 prostheses from 486 cases during July 1996 to June 2002 were analysed. Results The long term effectiveness of various treatments in residue crown group has no statistically significant difference(P>0.05); the effectiveness among self made post, performed screw post and casting crown post in residual root group has a statistically significant difference (P<0.05) . The total succeed rate of two groups was 85.0%. The main causes of failure were the loosed post and the abutment tooth disease.
