Occlusal contacts are subjected to constant change tooth restoration, extraction and prosthetic care always change the occlusal proportions. A discrepancy in occlusion may be realistically measured in micrometers. Accurate registration of occlusal contacts permits removal of occlusal interferences to establish a harmonious occlusion. Due to the availability of various occlusal indicating materials even a minute deflective contact can be detected and corrected. Any type of prosthesis made should be checked extraorally i.e. in laboratory and then intraorally for any occlusal interferences.
