Abstract:
The sinus cavity often limits the amount of available bone for the placement of implants in the posterior maxilla. The sinus lift operation and graft is a technique that can add grafted bone in excess of 10 to 16 mm through a lateral wall quadrilateral osteotomy. However, when moderate alveolar atrophy is present, an osteotome technique can provide an average bone height in crease of 3.5 mm. This article presents the trephine bone core sinus elevation graft, which is intended to increase bone height 4 to 8 mm. This procedure is especially indicated when adjacent teeth are present and there is only moderate atrophy of the alveolus.

The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
