Objective: The purpose of this study was to evaluate the efficacy of the alveolar ridge preservation technique using collagen sponge and xenograft after extraction. Study Design: Twenty patients were divided into the control group and the experimental group, which contained about 10 patients each. The control group patients were planned 3-unit bridge without performing implant and without special treatments for the extraction socket, and prosthetic treatments were performed after 3 months. In the experimental group, using collagen sponge and xenogeneic bone graft, alveolar ridge preservation was performed simultaneously with tooth extraction; implants were placed after 3 months. Clinical and histological evaluations and statistical analysis were performed. Results: The resorption rate of the width of alveolar bone 3 mm below the alveolar ridge of the control group was shown to be 20.74% and of the experimental group was an average of 14.26%, approximately a difference of 6% was observed, and it was statistically significant. New bone formation in the vicinity of bone graft materials was achieved well, and inflammation findings were not observed. Conclusion: The results indicated that in the ridge preservation using collagen sponge and xenograft, xenograft prevents the horizontal resorption of the alveolar ridge, and the upper collagen sponge blocks the infiltration of soft tissues to the lower area, and thus it has the advantage of the enhancement of bone fill.
