Retrospective volume analysis of bone remodeling after tooth extraction with and without deproteinized bovine bone mineral insertion

Objectives: The aim of the study was to analyze volume changes of post-extractive sockets grafted with or without deproteinized bovine bone mineral (DBBM) and a resorbable barrier. Materials and methods: This retrospective analysis utilized patients who had undergone tooth extraction. Sites, one per patient, 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
