Purpose: The aim of this investigation was to measure the temperature increase due to heat transferred to the implant-bone interface when the abutment screw channel is accessed or a metal-ceramic crown is sectioned buccally with diamond or tungsten carbide bur using an air rotor, with or without irrigation. Materials and Methods: Cobalt-chromium copings were cemented onto straight titanium abutments. The temperature changes during removal of the copings were recorded over a period of 1 minute. Results: The sectioning of coping with diamond bur and without water irrigation generated the highest temperature change at the cervical part of the implant. Conclusion: Both crown removal methods resulted in an increase in temperature at the implant-bone interface. However, this temperature change did not exceed 47 degrees C, the potentially damaging threshold for bone reported in the literature.
