A comparative, randomized, prospective, two center clinical study to evaluate the clinical and esthetic outcomes of two different bone grafting techniques in early implant placement

Background: Early implant placement combined with simultaneous contour augmentation was able to rebuild stable facial hard-tissue and soft-tissue contours that were esthetically pleasing. The purpose of this study was to evaluate the clinical esthetic outcome, when two different bone grafting materials were used.

Results: All 48 implants were clinically successful, and no significant differences were observed in mPI, mSBI, PD, KM, IC, DIB, PES, and WES at 1-year implant loading. The mean mucosal recessions of test and control group were unchanged, 0 and –0.02 mm, respectively. The mean DIB were –0.32 and –0.21 mm in test and control implants, respectively. The mean totals of PES/WES were 15.29 and 15.33 for the test and control groups, respectively, with no significant difference between groups.

Conclusions: This study demonstrated that autogenous bone plus DBBM and FDBA each combined with a collagen membrane both resulted in stable clinical and esthetic outcomes in early implant placement with contour augmentation after 1 year.
