Mx-grafter在即刻牙种植术中的临床应用

A clinical application of Mx-Grafter in the immediate dental implantation

目的 :评价在即刻牙种植术中用Mx grafter采取上颌结节处自体骨移植的应用方法和效果。方法 :2 1例 (2 5枚 )拔牙后即刻种植 ,采用Mx grafter由上颌结节处取自体骨 ,植入螺纹根状种植体与拔牙窝之间的间隙内或缺损处。骨的缺损情况在 1期手术和 2期手术时分别测量进行比较。结果 :3～ 4月后 ,2期手术显示自体骨改建形成了新骨 ,与种植体形成紧密的骨性结合 ,间隙或缺损被新骨修复。所有病例皆完成修复及行使功能。结论 :采用Mx grafter取自体骨植骨 ,满足了拔牙后即刻种植、植骨的需要。方法简单 ,值得临床推广。

Objective:To evaluate the effect of autogenous graftin g material of the maxillary tuberosity harvested by Mx grafter in the application of immediate implantation . Methods: 25 implants were i mmediately placed in tooth extraction sockets in 21 patients (7 females and 14 males) respectively, Autogenous grafting material of maxillary tuberosity harve sted by Mx grafter was used as a gap filling or defect restoring material arou nd screw type root form implant. Defect height and width were measured at the ti me of implant placement and at second stage surgery. Results: 3～4 months postoperatively, all implants demonstrated clinical stabilit y and the gap or defects were replaced with newly formed bone at second stage s urgery.All the implants were in function. Conclusions: Th e technique described affords a simplified and predictable manner for placement of implants into immediate tooth extraction sockets.
