Effects of Osteotomy Lengths on the Temperature Rise of the Crestal Bone During Implant Site Preparation

Aim:
To compare temperatures of the crestal bone during implant site preparation for different osteotomy lengths and implant systems.
Methods:
Bovine ribs were used to simulate the cortical bone of the human mandible. Three different implant systems were tested: Astra Tech, Ankylos, and XiVE. Six drills per system were performed, meaning each drilling set was used for 2 drills per 3 osteotomy lengths (8, 12, and 16 mm). Drilling force, drilling speed, drilling length, and temperature were recorded.
Results:
Differences in the maximum temperature of the crestal bone during the first drilling for various osteotomy lengths (P = 0.021) and all implant systems (P = 0.013) were observed. A similar result was showed during the second drilling; osteotomy lengths (P = 0.014) and drilling systems (P = 0.003). Second drillings showed lower temperatures of the crestal bone with statistical differences on all measurements (P
