The results of the meta-analyses showed a trend toward dimensional change in the bone crest in both height and width, with bone mineral grafts and collagen membranes, although without statistical significance. p = 0.21 and p = 0.22 for the BCH and BCW evaluations, respectively, in the pooled study analysis; p = 0.17 and p = 0.13 for BCH and BCW assessments, respectively, in the analysis of studies comparing bone mineral grafting and collagen membranes with spontaneous alveolar healing.
