Tu V, et al. - Herein, alveolar ridge preservation vs unassisted socket healing were compared for minimizing alveolar ridge dimensional changes following tooth extraction. With respect to minimizing the alveolar ridge dimensional changes from the process of bone remodeling, alveolar ridge preservation (socket grafting) in general seemed to produce more favorable outcomes than not using grafting materials. In minimizing bone height reduction, out of the 7 grafting materials included in the Bayesian network meta-analysis, freeze-dried bone grafts with membrane were seen to be the most effective. Autologous bone marrow had the most positive impact in minimizing bone width reduction during remodeling.
