This document specifies test methods and procedures for assessing the accuracy of a three dimensional numerical description of intra-oral surfaces acquired directly from a patient with a hand-held scanning device. The test methods are not applicable to ultrasonic, radiographic or magnetic resonance imaging methods.<\/p>\n
