目的：比较两种方法用于修复后牙游离缺失伴残根残冠的修复效果。方法：选择38例后牙游离缺失伴残根残冠的患者，按随机数字表法将其分为两组，分别采用冠外栓道式精密附着体义齿（n=17）和卡环固位活动义齿修复（n=21），5年后对修复效果进行评价。结果：冠外栓道式精密附着体义齿组出现1例崩瓷，无冠桩松动脱落、根折、桩折、牙周炎和根尖周炎，无活动部分破损，成功率为94.1%；卡环固位活动义齿组出现8例失败，成功率为61.9%，两组成功率比较差异有统计学意义（P<0.05）。结论：对于后牙游离缺失伴残根残冠的牙列缺损病例，选用冠外栓道式精密附着体义齿修复的临床效果较好，值得临床推广使用。
目的：比較兩種方法用于脩複後牙遊離缺失伴殘根殘冠的脩複效果。方法：選擇38例後牙遊離缺失伴殘根殘冠的患者，按隨機數字錶法將其分為兩組，分彆採用冠外栓道式精密附著體義齒（n=17）和卡環固位活動義齒脩複（n=21），5年後對脩複效果進行評價。結果：冠外栓道式精密附著體義齒組齣現1例崩瓷，無冠樁鬆動脫落、根摺、樁摺、牙週炎和根尖週炎，無活動部分破損，成功率為94.1%；卡環固位活動義齒組齣現8例失敗，成功率為61.9%，兩組成功率比較差異有統計學意義（P<0.05）。結論：對于後牙遊離缺失伴殘根殘冠的牙列缺損病例，選用冠外栓道式精密附著體義齒脩複的臨床效果較好，值得臨床推廣使用。

Objective:To compare the effect of two methods in restoration of bilaterally disto-extensive loss of posterior teeth,residual roots and crowns. Method:38 patients with bilaterally disto-extensive loss of posterior teeth were divided into two groups according to random number table method,and were treated by extra coronal key-way precision attachment(n=17)and clasp retention removable dentures(n=21)respectively. The restoration effect after 5 years was evaluated. Result:Only 1 case had porcelain fracture in the extra coronal key-way precision attachment group,and crown and post loose,shedding,root fracture,post fracture,periodontitis,periapical inflammation or damage of removable part were not reported;the success rate was 94.1%. 8 patients were failed in the clasp retention removable dentures group,Its success rate was only 61.9%. The success rate of two groups had significant difference(P<0.05). Conclusion:For the case of defective dentition with bilaterally disto-extensive loss of posterior teeth,it would be better to choose extra coronal key-way precision attachment,and it is worthy of clinical promotion.
