a comparison of heat generation in different depths of implant drilling site with and without a sleeve

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 35.4°c and without a sleeve was 34.5°c. 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.
