OBJECTIVES: The aim of the study was to analyze volume changes of post-extractive sockets grafted with or without deproteinized @entity291 bone mineral (DBBM) and a resorbable barrier. MATERIALS AND METHODS: This retrospective analysis utilized @entity1 who had undergone tooth extraction. Sites, one per @entity1 , were allocated to two groups: post-extractive non-grafted sockets (NG) and post-extractive grafted sockets with DBBM and resorbable barrier insertion (G). Maximal primary soft tissue closure was sought for both procedures. Before extraction and 6  months later, three-dimensional features of the sockets (linear indexes, areas, and volumes) and outcome variables at 6  months (volume- and surface changes) were acquired through computer tomography scans. Intra- and inter-group comparisons of the outcome variables were performed. Nonparametric tests were applied with a level of significance set at P  <  0.01. RESULTS: Twenty-four sites, 9 grafted and 15 ungrafted, were enrolled. Between baseline and the 6-month evaluation, significant bone @entity393 , superior surface shrinkage, and height reduction were registered for the G (72  mm(3) , 76  mm(2) , and 0.5  mm, respectively) and the NG group (274  mm(3) , 87  mm(2) , and 1.8  mm, respectively) with all P-values   <=  0.0039. A significant difference, regarding the percentage of the volume change, was registered between the two procedures with a @entity393 of 9.9% for the grafted sockets and 34.8% for the ungrafted ones (P-value  =  0.0073). CONCLUSION: Grafting of the sockets with DBBM and a resorbable barrier insertion seemed to reduce negative osseous remodeling in the short term when compared to that of the ungrafted sockets.
