PURPOSE: The aim of this study was to evaluate the heat generation in bone in vitro during the guided flapless drilling procedure and the effect of drilling methods on the heat generation.
MATERIALS AND METHODS: A model that has missing the first and second mandibular molars bilaterally was used. In group A, classical flap implant surgery was performed. In group B, flapless implant surgery using surgical guide was performed. In group C, flapless implant surgery using surgical guide without up-and-down pumping motion was performed. Temperature was measured with k-type thermocouple and a real-time digital thermometer. The thermocouples were placed at 0.5 mm away from the osteotomy area at the depths of 3 mm and 6 mm. The measured values were evaluated with independent t-test.
RESULTS: The mean temperature generated was 27.2℃ (SD ± 2.1℃) and 27.5℃ (SD ± 2.3℃) for groups A and B, respectively. These differences were not statistically significant. In group C, the mean temperature was 37.0℃ (SD ± 3.4℃). There were statistically significant differences between groups B and C with respect to the mean temperature.
CONCLUSION: These findings suggest that guided flapless drilling with up-and-down pumping motion may not significantly increase the bone temperature
