Angulation and inclination of clinical crown is important for diagnosing. Treatment planning and developing convenient orthodontic attachments. The aim of the study was to establish normative data with higher reliability on the angulation and inclination of clinical crown of Koreans with normal occlusion. This study employed the dental casts of 307 (male, 187: female. 120) adult normal occlusion samples. The angulation and inclination of clinical crown were measured by set-up model checker. In order to ensure reliability. intra- and inter-rater error were evaluated 3 times. The resultant data obtained had excellent reliability. however. when compared with the previous data as well as with gender difference clinically signiflcant interpretation was impossible because the whithin-dataset normal variation was high. which was common pattern of angulation and inclination measuring data of previous research. The result of this biometric study seemed to suggest more substantive design of the multivariate. high-dimensional interpretation methodology of these normal variation is required if more compatible orthodontic appliance could be developed.
