Investigation of the Effect of Osteotomies Performed Using the Osseodensification Technique on Heat Generation

Background: The aim of our study is to compare the potential temperature differences in bone resulting from angled and straight drilling at different depths using the osseodensification method.Materials and Method: In our study, three different groups were formed to observe the effect of angle and depth on heat generation during osteotomy performed using the osseodensification technique. Each group consisted of four different depths. The osseodensification procedure was performed at a 0-degree angle in the first group, a 17-degree angle in the second group, and a 30-degree angle in the third group. In each group, osteotomies were performed at depths of 0, 9, 11, and 13 mm, respectively, and the resulting temperature values were measured in degrees Celsius.Results: No statistically significant differences in temperature values were observed among the 0°, 17°, and 30° drilling angle groups at depths of 0 mm and 9 mm (p>0.05). However, at drilling depths of 11 mm and 13 mm, the average temperature values in the 0° group were significantly lower than those in the 17° and 30° groups (p<0.05). In all groups, temperature values increased significantly as drilling depth increased. Despite these increases, all recorded temperatures remained below the critical threshold of 47°C associated with thermal bone injury.Conclusions: Based on these results, it was concluded that not only drilling depth but also drilling angle increases the heat generated in the bone. Due to the limited number of studies in the literature regarding osseodensification and angled drilling, we believe that further clinical and laboratory studies are needed to provide clearer information.
