Fig. 8. Soft tissue dehiscence (a) CCXBB exposure 15 weeks after bone augmentation, the dehiscence healed 2 weeks later after reducing the graft exposure (b) after soft tissue augmentation and abutment connection leading to the loss of the mesial implant. After partial removal of the bone graft and place a connective tissue graft the area healed properly and a month later it was possible to replace the implant : Histomorphometric and immunohistochemical evaluation of collagen containing xenogeneic bone blocks used for lateral bone augmentation in staged implant
