This study compared the bone turnover and volume stability of bovine-derived xenografts (Cerabone) vs porcine-derived xenografts (MinerOss XP) in horizontal ridge augmentation (HRA) for veneer contour and extraction socket preservation (ESP), with a 6-month follow-up. Participants were divided into Group 1 (HRA + bovine), Group 2 (HRA + porcine), Group 3 (ESP + bovine), and Group 4 (ESP + porcine). Buccolingual ridge width was measured on CBCT scans at baseline and 6 months. Representative histologic core samples were taken from the ESP groups at 6 months. Each group comprised 10 subjects (40 subjects total). The buccolingual width for Groups 1 and 2 increased from 5.43 ± 1.82 mm and 5.75 ± 1.64 mm (P = .36) to 7.75 ± 1.91 mm and 8.75 ± 1.38 mm (P = .03), respectively. However, the buccolingual widths for Groups 3 and 4 decreased from 6.3 ± 1.26 mm and 6.74 ± 1.29 mm (P = .16) to 5.8 ± 1.21 mm and 6.61 ± 1.56 mm (P = .01), respectively. Significantly lower dimensional changes were noted in Group 4 at 6 months. Porcine xenografts serve as a stable biocompatible osteoconductive bone substitute and expand a clinician’s choice of bone grafts in dental applications.
