Effect of Guided Surgery on Heat Generation from Implant Drilling with External Irrigation in Human: A Comparative Cross-Sectional Pilot Study

Description :

Aim: the aim of this study is to measure in-vivo the temperature alterations during implant site preparation using a 3-dimensional surgical guide with external irrigation as a first step. Second aim would be to compare thermal changes with conventional drilling to sequential drilling. Materials and Methods: This is a comparative cross-sectional pilot study including 20 patients. Patients will undergo an optical and CBCT scan first, followed by a surgical simulation and the fabrication of a 3D printed surgical guide. This teeth supported guide will be used during the surgery to guide implant placement and to allow temperature measurement. Bone temperature will be measured by the TP200 glass thermo-microsensor [UNISENSE] at a pre-defined point : half of the implant length and 0,6mm from the implant diameter. The temperature will be measured at this site while performing the osteotomy with each drill (starting with the pilot drill to the last drill before the implant insertion). In this way for each implant placed 4 to 5 measures will be recorded.
