Onlay bone grafting: when and how?
Summary:
There are many advantages to the bone grafting coffering technique which requires autogenous bone grafts taken from a ramus area with a resorbable membrane. Bibliographic support and clinical experience in this technique show that the risk of bone resorption is reduced and that there are minimal complication risks. In addition, the bone quality attained during implant placement can reach a good primary stability with an optimum positioning in a second phase. This technique remains dependent on the experience of the treatment team and should only be chosen after evaluating other treatment options.
