504 Theories and techniques of oral implantology

The edentulous ridge was injected with bilateral nerve blocks as well as infiltration anesthesia (Fig. 11-136) . An incision was made along the crest of the ridge from retromolar pad area to retromolar pad area. The tissues were reflected to expose the bone. The groove for the first blade was made in

the right molar area and the implant was set into it and tapped in until its shoulders were buried between the existing cortical plates (Fig. 11-137).

The second groove was made in the cuspid-bicuspid area. (If it is necessary to curve the groove in this area to follow the crest, the implant can be

Fig. 11-138. Because more bone existed anteriorly, a blade longer in its superior and inferior dimensions was used.

Fig. 11-139. Because there was not enough room to place double-headed blades that were wider anteriorly and posteriorly, four smaller single-headed blades were used.
