Ridge regeneration of damaged extraction sockets using rhBMP‐2: an experimental study in canine

Abstract

Buccal-bone-deficiency may lead to significant volume reduction after tooth extraction along the entire length of the socket, and socket grafting accompanied by rhBMP-2 or covered with a membrane can be candidate therapies for preservation of the buccolingual dimension and successful ridge regeneration.

Ridge preservation of extraction sockets with chronic pathology using Bio‐Oss® Collagen with or without collagen membrane: an experimental study in dogs

“…This finding was supported by the previous study (Lee et al. ) in which the socket grafting with a collagen membrane enabled preservation of bucco‐lingual dimension compared to grafting with deproteinized bovine bone mineral only. A dome‐shaped configuration, which was reported by Araujo et al.…”

Volumetric, Radiographic, and Histologic Analyses of Demineralized Dentin Matrix Combined with Recombinant Human Bone Morphogenetic Protein-2 for Ridge Preservation: A Prospective Randomized Controlled Trial in Comparison with Xenograft

“…However, at the level of 5 mm (RW-5), the Bio-Oss ® Collagen group exhibited significantly greater loss in width (0.50 ± 0.19 mm), compared to Group B (0.20 ± 0.15 mm) treated with DDM. Nevertheless, the apical portion of the alveolar socket (RW-5) is less important and dynamic, as the majority of the apical portion of the buccal bone plate is lamellar bone [41]. The marginal portion of the crest (RW-1 and RW-3 mm) is more critical in the bone remodeling cascade due to the bundle bone.…”

Three‐dimensional analysis of bone remodeling following ridge augmentation of compromised extraction sockets in periodontitis patients: A randomized controlled study

“…Data on the healing pattern of sockets with compromised bony walls are limited. A decrease of about 60% in the horizontal dimensions was observed in buccal‐bone‐deficient alveolar sockets within the first 8 weeks of healing in the animal model (Lee et al., ). If compared with a 35% reduction in intact extraction sites over a 6‐month period (Araújo & Lindhe, ), it could be expected that compromised alveolar sockets undergo more pronounced atrophy as a result of the natural remodeling process.…”
