This is a very detailed, practical workshop that will teach participants how to restore a narrow upper anterior ridge to enable implant placement. The possible treatment options will be discussed, and participants will then perform a block graft procedure using an open flap. Various incision lines will be shown, including the most appropriate design, which will then be performed by the participants. Special models have been developed that simulate the condition often found in patients. In addition, an effective flap raising technique will be demonstrated, which allows good, secure closure at the end of the procedure. The various types of block grafts that can be used will be discussed, including the use of irradiated bone blocks, as well as taking bone from the chin and ascending ramus. Participants will shape bone blocks to fit the defects in the models and then screw the block into place using dental surgical bone screws. The need for a tension free closure will be emphasized, minimizing the possibility of dehiscence and subsequent development of infection in the graft.
