The effect of irrigation on osteotomy depth and bur diameter.

A device to measure bur temperature using thermocouple technology was developed. A block of bovine bone was subjected to computerized tomography scanning to confirm bone density and configuration similar to that of a human mandible. Bone temperature was measured via a thermocouple probe. During osteotomy preparation, bur temperature was shown to exceed the surrounding bone temperature. Irrigation greatly reduced bur temperature. Osteotomies were made to depths of 8.5, 10.5, 13.5, 15.5, 18.5, and 20.5 mm. Bone density played a far greater role in bur temperature elevation than did osteotomy depth. Adding a pilot drill to the drill sequencing tended to lower bur temperature; widening of osteotomies from 2 to 3 mm wide generated as much heat as did the making of the 2-mm-wide osteotomy.

The role of incision design and location in the healing processes of alveolar ridges and implant host sites.

This research examined the nature and role of a linea alba, found consistently at the crest of edentulous ridges in dogs. Angiovist dye was used to outline the microvasculature in these regions. The findings demonstrated a zone of avascularity directly beneath each linea alba. When novel incision designs were used in the gingivae and the outlined mucoperisteal flaps were elevated and then replaced, alterations in underlying bone morphology were noted. In a subsequent study during which implants were placed, a direct relationship was noted between incision design and level of pericervical bone support.
