Abstract

This study investigated pain experience following dental implant placement in relation to insertion torque using questionnaires. A total 80 implants were placed in 20 patients. Each patient received 4 implants at different times. One implant was inserted and, then, after 40 days was placed the second implant, after 80 days was placed the third implant and after 120 days was placed the fourth implant. At each time the peri-implant bone levels were evaluated on intraoral radiographs taken with the paralleling technique.The implants were placed with a dynamometric key at 35N, 50N, 65N, 85N. Patients were asked to evaluate their pain experience during surgery, 24 hours after surgery, and at 2 days, 4 days, 1, 2, and 4 weeks after surgery on special pain assessment forms. A separate form was used for each time point. Pain was assessed using a descriptive numerical rating scale of 0 to 10, with 0 indicative of no pain and 10 representing the worst pain imaginable. Patients were instructed that a score of 1 to 3 was indicative of mild pain, 4 to 6 was indicative of moderate pain, and 7 to 10 was indicative of severe pain. A significant correlation pain scores and insertion torque was found between group III and group IV vs group II and group I during surgery, at 24 hours, 2 days, 4 days, 1 week, 2 weeks p≤0.05. No statistical difference was found between group I vs. group II during surgery, at 24 hours, 2 days, 4 days, 1 week, 2 weeks p≥0.05. In conclusion, elevated insertion torque values produces pain and resoption of the crestal bone around the implants.
