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.
