Abstract
Aims: Thermal trauma during implant site preparation may adversely affect bone vitality and compromise osseointegration. Drilling parameters such as angulation and depth are considered important factors influencing heat generation in bone during implant surgery. The aim of this in vitro study was to evaluate the effect of different off-axis osteotomy angulations and depths on intraosseous temperature changes during implant site preparation. Methods: This in vitro experimental study was conducted using fresh bovine femur cortical bone specimens. Implant osteotomies were performed at three different off-axis osteotomy angulations (0°, 17°, and 30°) and four measurement depths (0, 9, 11, and 13 mm). Temperature changes were recorded using K-type thermocouple sensors positioned 1 mm from the drilling site. Drilling was performed for a standardized duration under constant irrigation. The maximum temperature reached at each depth and angle was recorded and statistically analyzed. Results: The mean intraosseous temperature increased from 35.69°C, 35.68°C, and 35.79°C at baseline to 41.45°C, 41.86°C, and 42.37°C at 13 mm for the 0°, 17°, and 30° groups, respectively. Temperature increased significantly with depth in all groups (p<0.05), except between 11 and 13 mm in the 17° (p=0.091) and 30° (p=0.138) groups. At 11 and 13 mm, temperatures were significantly higher in the 17° and 30° groups than in the 0° group (p<0.05). Conclusion: Within the limitations of this in vitro study, increased drilling angulation and depth were found to significantly elevate intraosseous temperature during implant site preparation. These findings suggest that drilling geometry should be carefully considered during implant site preparation to help control temperature elevation.
