17 distal extension cases were treated with IMZ implants supporting a fixed-removable bridge connected to a natural tooth abutment with a precision attachment. Instead of the polyoxmethylene internal shock absorber an identically dimensioned titanium element was incorporated in the implants of every second patient. Patients were monitored on a recall schedule. Implant and tooth mobility, pocket probing depth, and bone loss were the parameters evaluated. The results after a mean incorporation time of 16.5 months indicate that, at least during this initial time of function, there are no differences between a mobile and rigid bedding of the superstructure on the implants.
17例远中延伸病例采用IMZ种植体支持固定-可摘桥修复，该桥通过精密附着体与天然牙基牙相连。每隔一位患者的种植体中，用尺寸相同的钛元件取代了聚甲醛内部减震器。按照回访计划对患者进行监测。评估的参数包括种植体和牙齿的松动度、牙周袋探诊深度以及骨吸收情况。平均植入时间16.5个月后的结果表明，至少在功能的最初这段时间内，上部结构在种植体上采用活动式或固定式衬垫并无差异。
