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.

Methods: Forty-eight patients were randomly assigned into two groups.
