- Abstract
- Objectives: The purpose of this study was to evaluate the temperature change during low-speed drilling using infrared thermography. Material and Methods: Pig ribs were used to provide cortical bone of a similar quality to human mandible. Heat production by three implant drill systems (two conventional drilling systems and one low-speed drilling system) was evaluated by measuring the bone temperature using infrared thermography. Each system had two different bur sizes. The drill systems used were twist drill (2.0 mm/2.5 mm), which establishes the direction of the implant, and finally a 3.0 mm-pilot drill. Thermal images were recorded using the IRI1001 system (Infrared Integrated Systems Ltd.). Baseline temperature was 31 +/- 1 degrees C. Measurements were repeated 10 times, and a static load of 10 kg was applied while drilling. Data were analyzed using descriptive statistics. Statistical analysis was conducted with two-way ANOVA. Results and Conclusions: Mean values (n=10 drill sequences) for maximum recorded temperatue (Max T degrees C), changes in temperature (Delta T degrees C) from baseline were as follows. The changes in temperature (Delta T degrees C) were 1.57 degrees C and 2.46 degrees C for the lowest and the highest values, respectively. Drilling at 50 rpm without irrigation did not produce overheating. There was no significant difference in heat production between the 3 implant drill systems (p>0.05). No implant drill system produced heat exceeding 47 degrees C, which is the critical temperature for bone necrosis during low-speed drilling. Low-speed drilling without irrigation could be used during implant site preparation.
