摘　　要：目的:研究太极扣附着体在肯氏Ⅱ型牙列缺损修复中其远中基牙近、远中牙槽骨高度的变化。方法:对21例完成太极扣附着体修复的肯氏Ⅱ型牙列缺损患者,分别于修复完成当天、修复后1、3和6个月拍摄数字全景片,测量远中基牙近、远中牙槽骨嵴顶至根尖点的垂直距离,观察和比较修复前、后远中基牙牙槽骨高度的变化。采用SPSS16.0软件包对数据进行配对t检验。结果:太极扣附着体义齿修复完成当天、修复后1、3和6个月时,远中基牙的近中及远中牙槽骨高度均无明显降低(P>0.05)。结论:数字全景片观察显示,太极扣附着体义齿在肯氏Ⅱ型牙列缺损修复半年后,其远中基牙牙槽骨高度无明显变化,太极扣附着体在游离端义齿修复中有利于基牙的健康和稳定。PURPOSE： To observe the alveolar height changes of the distal abutments in Kennedy II dentition defect restored with Stern ERA attachment.METHODS： Twenty-one Kennedy II dentition defect patients restored with Stern ERA attachment were observed at the day of restoration and 1 month,3 months and 6 months after restoration.Digital panoramic radiographs were taken to measure the vertical distances from the distal and the mesial alveolar bone crest to the apical point in the distal abutments and were used to observe and compare the alveolar height changes of the distal abutments.The data was analyzed with SPSS16.0 software package for Student＇s t test.RESULTS： The distal and medial alveolar height of the distal abutments was not significantly reduced（P〉0.05） 1 month,3 months and 6 months after restoration with Stern ERA attachment.CONCLUSIONS： According to the digital panoramic radiograph,the alveolar height of the distal abutments in Kennedy II dentition defect restored with Stern ERA attachment was not significantly changed in 6 months after restoration.It may benefit for the the health and stability of the distal abutments by using Stern ERA attachment in Kennedy II dentition defect.
