Thermal Analysis of Dental Impression Waxes

Ten dental impression waxes were characterized by penetration and differential thermal analysis. Penetration and initial transition temperatures were directly correlated. Penetration at 37 C ranged from 2.5 to 22% for bite waxes and was 100% for corrective waxes. Distortion of an impression wax may occur upon removal from the mouth.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/67462/2/10.1177_00220345780570011601.pd
