Heat generated when threaded pins are cut: A comparison of techniques

Heat Generation on Implant Surface During Abutment Preparation at Different Elapsed Time Intervals

“…It has been shownthatbyremovingtheburfrom the tooth intermittently for even a few seconds during crown or abutment preparation can reduce the heat generation considerably. 9,14 The results of the study have clearly shown that cutting the implant abutment using water-coolant temperature of 20 6 1°C will not increase the implant surface temperature from the starting temperature of 37°C but rather it will cause a decrease in the implant fixture surface temperature. Cutting the implant abutment using a water-coolant temperature of 32 6 1°C did cause an increase in the implant fixture surface temperature which increases to 41.8°C from the starting temperature of 37°C.…”

“…13 The air water spray has been found to be the most effective. 14 In addition, the presence of water spray increases the cutting rate of the bur when cutting enamel compared to the cutting rate when no coolant is used. 15 During the preparation of the implant abutment, excessive heat generation at the implant bone interface may cause irreversible bone damage and loss of osseointegration.…”
