Reliability of drilling torque values measured with a novel measurement drill for guiding implant placement protocols.

Background: A novel measurement drill was fabricated to analyze bone density. We hypothesized that evaluating the correlation between primary stability and bone density-assessed using drilling torque values obtained with a novel drill-under various bone density conditions could aid in selecting appropriate implant placement protocols. This study aimed to determine whether drilling torque values measured using the novel drill could serve as a guide for implant placement protocol. Material and Methods: Experiments were conducted using solid rigid polyurethane bone blocks corresponding to Misch classifications D2-D4. After measuring the drilling torque, the implant sockets were prepared under two conditions: undersized and normal-sized drilling protocols. The implant was placed, and the insertion torque value was measured as the primary stability. Results: A correlation was observed between the drilling and insertion torque values across different bone densities and surgical protocols. Conclusions: Drilling torque measurements using the novel drill may be a useful method for selecting appropriate implant placement protocols.
