Analysis of temperature in conventional and ultrasonically-assisted drilling of cortical bone with infrared thermography.BACKGROUND
 One of the major concerns in drilling of bone is thermal necrosis that may seriously affect healing at interfaces with fixtures and implants.  This paper studies temperature rise in bovine cortical bone drilled with CD and UAD techniques and their comparison using infrared thermography.


 Higher levels of the drilling speed and feed rate were found responsible for generating temperatures above a thermal threshold level in both types of drilling.
