摘要
通过比较１７例无牙颌患者５年前后的牙槽骨吸收程度，发现女性牙槽骨吸收程度Ｔ值５年前后差异无显著性（Ｐ＞０．０５），而男性Ｔ值５年前后差异有显著性（Ｐ＜０．０５）；牙槽骨吸收程度Ｔ值与戴牙时间呈正相关。提示在研究无牙颌牙槽骨吸收或比较不同研究者的研究结果时，应重视研究对象的戴义齿时间这一构成因素。
Abstract To investigate the bone resorption of the residual ridge at 5 year's interval,the areas(S1,S2,S3)were measured on supermosed cephalographic tracings of 17 edentulous patients(8 women and 9 men)with the special plamimeter in square millimeter.the degree of the residual ridge resorption became more severe with the time lasting,but there was no significant difference between the start of the study and after 5 year's interval in women group, while the significant difference existed in men group.A significant positive relationship was found between the degree of the residual ridge resorption and the term of complete denture wearing.It suggests the tern1 of complete denture wearing must be paid attention to when studying RRR,and comparing the results provided by different researchers.
