Аннотация The objective of the study is to develop an algorithm for determining the correlation between tooth size, dental arch parameters and the craniofacial complex. Material and methods. 178 patients with physiological occlusion of permanent teeth and neutral type of jaw growth were examined to determine the correlation between tooth size, dental arch parameters and craniofacial complex. Correlation between tooth size and dental arch parameters was determined based on the relationship of the major dental arch parameters and the size of 12 teeth including first molars, premo-lars, canines and incisors, as well as the width of the face between zygomatic points and the distance between lateral surfaces of the wings of the nose. Results. The algorithm is based on the dentofacial index (D. F. I.), calculated as the percentage ratio of the sum of four incisors to facial width. Conclusions. In patients with mesodontism and physiologic occlusion of permanent teeth the dentofacial indexwas23.5%±1.5%. An increase in the dentofacial index up to 25.1% was indicative of individual macrodontia of four upper anterior teeth. The value below 21.9% indicated individual micro-dontia of four upper anterior teeth. The correlation between individual teeth of different types and compared the size of teeth in certain segments and dental arch parameters has been evaluated.
