简要总结
Comparison of the clinical healing of simultaneous vs. delayed grafting for dental implant placement.
详细描述
The primary aims of this study are to compare the clinical and histologic results of a traditional ridge preservation with implant placement at 16 weeks (control group) with early implant placement (8 weeks) with simultaneous contour augmentation as described by Buser (test group).
