Professor Dr. Marc Hürzeler, Munich/Germany, improves the width of the alveolar ridge in order to achieve a sufficient bone supply to place implants into the position distal of the lower left canine. Therefore he harvests alveolar bone plates retromolarly to reconstruct the alveolar ridge. Prof. Hürzeler, Munich/Germany, raises a full flap in the lower left jaw to expose the bone to be augmented.

After cleaning the bone of periosteum remnants a releasing incision of the intact periosteum is performed to increase the flexibility of the flap. With careful protection of the soft tissues a Lindemann bur is used to harvest a linea obliqua bone block. Followed by the decortications of the bone the bone block is split in two pieces.

A second bone block is harvested and ground to small bone chips and mixed with BioOss. The outer layer of the first bone block is fixed on the residual bone and the BioOss and bone mixture positioned between the residual bone and the outer layer of the first bone block. The second layer of the first bone block is screwed on top of the augmented area and the wound is closed avoiding any tension.
