Comparison of Healing Following Tooth Extraction With Ridge Preservation Using Anorganic Bovine Bone Mineral Particulate and Self-Expanding Composite Graft.

OBJECTIVES: To study the radiographic mean grey values after bone grafting and to clinically evaluate the intraoral alveolar ridge dimensional stability with anorganic bovine bone mineral (ABBM) particulate and a patented self-expanding composite graft (SECG) after 6 months of healing.

METHODS: A total of 20 single-rooted tooth-extraction sites grafted with either ABBM or SECG were evaluated radiographically and clinically after 6 months of healing, prior to dental implant placement. A multivariable mixed regression model was used.

RESULTS: Mean grey values at the coronal, midroot, and apex levels within the socket were compared. A significant difference was shown in the midroot and apex maxillary regions. For both of these regions, the estimated mean grey value of ABBM was significantly lower than that of SECG. No significant difference was noted in the ridge-width change patterns between the two materials.

CONCLUSION: This study supports that suggestion that newer SECG is as efficacious in terms of mean grey value and alveolar ridge stability as the previously available ABBM.
