Abstract

Background:  To evaluate and compare the effect of drilling speed: 850rpm, 1150rpm & 1500rpm on the temperature rise at three different depth: 8mm, 10mm & 11.5mm during implant site preparation in goat mandible. Materials & Method: Drilling was done in the posterior cortical region of 36 samples of goat mandible and randomly divided into 3 groups and 3 subgroups; group 1 included drilling with 850rpm at 8mm, 10mm & 11.5mm depth, group 2 included drilling with 1150rpm at 8mm, 10mm, 11.5mm and group 3 included drilling at 1500rpm with 8mm, 10mm &11.5mm. 2.8mm twist drill was used for drilling and thermocouple device was used for the measurement of heat generated during drilling. Statistical Analysis: One way analysis of variance (ANOVA) was used and Shapiro Wilk test was used to check which all variables were following normal distribution. Results:  Overall higher temperature rise was seen during drilling with 850rpm and minimum temperature rise was seen during drilling with 1500rpm and significant temperature difference was seen at 10mm depth also. (p<0.05) Conclusion: Significant temperature rise during implant site preparation while using slow speed drilling and temperature decreased during implant site preparation while drilling with higher speed.
