摘　　要：目的研究栓体栓道式精密附着体义齿在双侧后牙游离缺失(肯氏Ⅰ类)病例修复中的应用及临床观察。方法对在我院就诊的26例双侧后牙游离缺失患者采用了栓体栓道式精密附着体义齿修复,分别在第一次戴入、3个月、6个月、12个月、24个月等不同时间对咀嚼效率、固位力、牙周指数[包括牙龈沟指数(GI)、牙周探诊深度(PD)]进行检测并进行统计分析。结果26例患者修复后的舒适度及美观等主观感觉都比较满意。咀嚼效率在3个月、6个月、12个月、24个月与初次戴入相比较增高且具有统计学意义;固位力随时间增加呈下降趋势,仅在24个月与初次戴入减少且具有统计学差异;牙周指数检测中牙龈指数(GI)仅在戴入后3个月时增加有统计学意义,牙周探诊深度在几个检测时间点没有统计学差异。结论在双侧后牙游离缺失病例的修复中,栓体栓道式精密附着体具有美观、稳定、咀嚼效率高等优点,是一种有效的修复方法。Objective To study the clinical application of the key-key attachment used in the bilateral molar missing cases （ Kenne- dy I）. Methods 26 patients with bilateral molar missing （Kennedy I） were selected and were repaired with key-key attachment den- ture. And at the beginning,3 month,6 month, 12 month and 24 month, the masticatory efficiency, attachment retentive force, and perio- dontics index（GI,PD） were investigated and were analysised by stastic software. Results 26 patients treated with key-key way attach- ment were satisfied with the denture. The masticatory efficiency statistically increased at the time of 3 month,6 month,12 month and 24 month. The retentive force decreased with time, and at the 24 month it had statistically significant compared with the first time. The gin- gival index （GI） statistically inceased at the time of 3 month. The periodontics probing depths （PD） had no significant change. Con- clusions The key-key attachment is a kind of esthetic,stable prosthetics restoration method with high efficiency.
