Avila-Ortiz G, et al. – Researchers conducted this systematic to examine the evidence on the impact of different modalities of alveolar ridge preservation (ARP) vs tooth extraction alone in function of relevant clinical, radiographic, and patient-centered outcomes. They identified nine different ARP treatment modalities: bovine bone particles (BBP) + socket sealing (SS), construct made of 90% bovine bone granules and 10% porcine collagen (BBG/PC) + SS, cortico-cancellous porcine bone particles (CPBP) + SS, allograft particles (AG) + SS, alloplastic material (AP) with or without SS, autologous blood-derived products (ABDP), cell therapy (CTh), recombinant morphogenic protein-2 (rh-BMP2), and SS alone. They observed that sites exhibiting a buccal bone thickness > 1.0 mm presented more favorable ridge preservation results than sites with a thinner buccal wall. Conclusively, ARP was noted as a useful therapy to mitigate the dimensional reduction of the alveolar ridge after tooth extraction.
