A The patients were randomly divided into rhBMP-2/BioCaP/β-TCP, β-TCP, and natural healing groups; B tooth extraction, C the tooth socket filled with either rhBMP-2/BioCaP/β-TCP or β-TCP in relative groups, D the first layer of collagen membrane covered the alveolar sockets and 2-3 mm over the socket edge), E the second collagen membranes, F sutured, G 2 weeks later, took out the suture, H after 6 weeks, soft tissue flap releasing, I a trephine drill (outer diameter 3 mm, inter 2.3 mm diameter) is used to obtain the biopsy, J collected biopsy (2.3 mm in diameter × 6 mm in height)
