The objective of this study was to evaluate the heat generation in vitro during the flapless drilling procedure using surgical drill guides. Ten resin models with bilateral edentulous tooth spaces in the first and second molars in the mandible were used in this study. On one side of the mandible, drilling was performed with a flapless approach using a surgical drill guide. On the other side of the mandible, drilling was performed with a flap approach. The temperature changes were measured during final drilling by thermocouples. The mean maximum temperatures during drilling with guided flapless procedures were 29.5 °C and 32.6 °C at the depths of 3 and 6 mm, respectively, whereas for flap procedures they were 29.4 °C and 31.3 °C. There was no statistically significant difference between the groups. These findings suggest that drilling with external irrigation in an up-and-down pumping motion may not lead to a significant increase the bone temperature during a flapless procedure using surgical drill guides.
