Abstract:

Bone, despite its apparent hardness, is biologically a very vulnerable tissue due to its low vascularization and slow growth. In dentomaxillofacial implant procedures, bone can be devitalized by heating. The implant is then not surrounded by bone but by fat or other connective tissue with faster growth. This leads ultimately to the failing of the implant. Drilling generates heat which can reach temperatures above the critical temperature of bone (47ᇆ°C). The subject of the present study is to evaluate if newly developed implant drills can contribute by their material (ZrO) and design to less heating of the bone during implant site drilling. In previous studies bone surface temperature was measured using an IR camera or bone temperature was assessed using embedded thermocouples. In the present study, the temperature of the drill (and attached debris) was measured after the end of the drilling process. This measuring approximates as much as possible the temperature inside the drill hole.
