Abstract

We measured the rise in the intraosseous temperature caused by freehand drilling or drilling through a surgical guide, by comparing different temperatures of irrigation fluid (10°C, 15°C, and 20°C), for every step of the drilling sequence (diameters 2.0, 2.5, 3.0, and 3.5mm) and using a constant drilling speed of 1200rpm. The axial load was controlled at 2.0kg. Bovine ribs were used as test models. In the guided group we used 3-dimensional printed surgical guides and temperature was measured with a thermocouple. The significance of differences was assessed with the Kruskal-Wallis analysis of variance. Guided drilling with 10°C irrigation yielded a significantly lower increment in temperature than the 20°C-guided group. When compared with the 20°C freehand group, the reduction in temperature in the 10°C guided group was significantly more pronounced at all diameters except 3.5mm. Finally, when the 10°C-guided group was compared with the 15°C groups, the temperature rise was significantly less at 2.5 and 3.0mm than with the guided technique, and at 3.0mm compared with the freehand technique. We suggest that the use of 10°C pre-cooled irrigation fluid is superior to warmer fluid for keeping temperature down, and this reduces the difference between guided and freehand drilling.<br /> (Copyright © 2016 The British Association of Oral and Maxillofacial Surgeons.
