ABSTRACT
STATEMENT OF PROBLEM:
Several studies have demonstrated the harmful role of heat generation during implant site drilling in subsequent bone healing. However, heat generation during implant placement should also be carefully considered.PURPOSE:
The purpose of this in vitro study was to evaluate thermal change in a resin block during motorized and manual implant placement with and without saline irrigation. MATERIAL ANDMETHODS:
Thermocouple probes were placed in resin blocks to measure the thermal change during forty 3.75x15-mm self-tapping cylindrical screw implant placements as follows MtI group, 10 motorized implant placements with external saline irrigation; MtNI group, 10 motorized implant placements without irrigation; MI group, 10 manual implant placements with external saline irrigation; MNI group, 10 manual implant placements without irrigation. The temperature values were recorded with a data acquisition system with a 20-channel multiplexer module connected to a personal computer. The normality of data distribution was assessed with the Shapiro-Wilk test and the homogeneity of variances with the Levene test. The mean temperatures of the groups was assessed with the 3-way ANOVA test followed by the Tukey HSD test for normal distribution and the Games-Howell test for non-normal distribution (α=.05).RESULTS:
The rate of temperature rise in the resin blocks was 1.1°C to 7.3°C. The highest mean temperature was present in the group for manual implant placement without irrigation (26.2 ±1.1°C), and the lowest thermal change was in the motorized implant placement group with external saline irrigation (23.6 ±1.0°C).CONCLUSIONS:
The thermal change in resin blocks during motorized implant placement was lower than manual implant placement, especially with external saline irrigation.
