| Abstract | ||
| Aims: To measure the heat generated from 3 drilling speeds (1250,2000, and 2500 rpm) using the armamentariumof ELIT implant systems. Materials and methods: Temperature was measured withthermocouple technology in vitro using the bovine femoral cortical bone model. Intermittent drillingwas accomplished by using normal hand force that used in implant preparations. External irrigation at40 mL/min with normal saline was used with drilling depth at a depth of 7mm and diameter 3.75. Heatmeasurements were recorded after final drilling step. Results: Result showed temperature increasesrelated to the time of drilling and the speed of 2500 rpm accompanied with lowest temperature. Conclusions:From a heat generation, we concluded that preparing an implant site at 2500 rpm could decreasethe risk of bone damage, which may affect the initial healing of dental implants. This may decreasethe devital zone adjacent to an implant after surgery. | ||
