Fig. 2From: Radiographic and histological evaluation of bone formation induced by rhBMP-2-incorporated biomimetic calcium phosphate material in clinical alveolar sockets preservationIntra-oral photographs of socket preservation and dental implant surgery. A The upper left first premolar needed to be removed. B The gingival biotype was a thick tissue biotype. C Tooth extraction. D The tooth socket was filled with rhBMP-2/BioCaP/β-TCP. E Two layers of collagen membrane covered the alveolar socket. F Sutured. G 6 weeks later. H Soft tissue flap releasing. I Obtained the biopsy and inserted an implant. J, K Guided bone regeneration (GBR) for the horizontal bone gain. L SuturedBack to article page
