Abstract

Objective: This study measures the temperature rise in dental implant during drilling into the screw to create a post space for the retreatment of cement-retained implant prosthesis with a fractured abutment screw.
Methodology: Implant was embedded in acrylic block and a screw was tightened onto it. This assembly simulated a condition where the abutment screw was fractured and the cemented prosthesis, along with the abutment, had dislodged. A hole was drilled with 5 seconds in-and-out motion through the screw in the implant using a high-speed handpiece with coolant. Temperature changes were measured using a thermocouple. A fibre-post was cemented using GIC. Core build-up was done with composite and a new prosthesis was fabricated.
Results: There was a temperature fall of 2.8°C (25.4°C-22.6°C) while drilling through the screw at the cervical portion of the implant. There was a temperature rise of 1.5°C (25.4°C-26.9°C) when the drilling was performed at the deeper level towards the apex of the implant.
Conclusion: Since the temperature did not exceed 37±10°C while drilling into the screw to create the post space, this procedure can be employed as a retreatment measure for the fractured screw cases in cement-retained implant prosthesis without causing adverse rise in bone temperature.
