Study Spotlight

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

Data from this randomized controlled clinical trial showed that Oracell Acellular Dermal Matrix provided a viable alternative to connective tissue graft

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.
