Abstract :
Introduction: The purpose of this study was to compare the heat generated from different depths of an implant drilling site with and without a sleeve. Materials and methods: In this study, 60 cortical bone samples were used and a load of 2.0 kg was applied. rilling for implant surgery, we used a diameter of 4.3 mm and a normal sleeve. Heat was measured from 3 different depths(3,6, and 9 mms). Data was analyzed with a three-way analysis of variance by Newman-Keulsmultiple comparison procedure. The significance level was set to a p-value of 0.05. Results: The mean maximum temperature with a sleeve was 35.4ʹC and without a sleeve was 34.5ʹC. Thermal rise was lowest in the sleeve group and highest in the sleeveless group. There was a significant difference between the sleeve and nonsleeve group (P= 0.002). There was also no significant differences between the different depths of the three measurements (P= 0.068). Conclusion: Within the scope of this invitro study, thermal rise during implant site preparation was lower in conventional drilling compared to the use of a sleeve. Hence, the difference was statistically significant.
