Summary: This study aimed to compare temperature changes during bone drilling for implant placement using non-limiting and limiting surgical guides at cortical and cancellous bone levels. Bovine rib samples were utilized, with 44 specimens divided into limiting and non-limiting guide groups. Temperature changes were recorded using thermocouples at different depths. Results indicated a statistically significant difference in temperature rise between the two guide types, with limiting guides showing higher readings. However, the temperature rise was deemed clinically insignificant and within a safe range for both techniques.
