[Bone augmentation in implant surgery]

The authors experience on twelve patients in the field of bone grafting prior to implant surgery is presented. The technique employed depends largely on the anatomical location of bone insufficiency, such as: 1) Where there is not enough bone beneath sinus locations, grafting with cancellous iliac bone blended with coral particles is suggested. 2) Where the jaw is not sufficiently thick, such as in the incisor-cuspid regions, the authors employ cancellous and/or cortical bone grafts. 3) Horizontal osteotomy and interposition of cortical-cancellous bone graft is proposed where there is a lack of bone height in the incisor-cuspid regions. The results of the various techniques are analysed from a clinical, radiographic and histologic perspective. Twelve patients have been treated with 2 years follow-up.
