Abstract

The study of the area of occlusal surface of the teeth, as well as the degree of differentiation and reduction are of great importance when conducting reconstructive therapy. The ability to restore the occlusal surface of the teeth with a different degree of differentiation will allow dentists to improve the technology of restoration of tooth crowns based on the principles of biomimetics. Aim — creation of an integral indicator, the index of a tooth relief index, which characterizes the shape, volume, degree of differentiation of the tooth crown. Materials and methods. The object of the study was 200 teeth of intact teeth of individuals of the Caucasian race, aged 18 to 30, removed according to orthodontic and surgical indications. A morphometric study of tooth areas was carried out using modern methods of computer diagnostics and recording the data on electronic media. Results. The results of the study show that when measuring 20 intact molars, the integral value, the tooth relief index, averages 24%. 20 intact premolars, the integral value is the index of tooth relief, an average of 21%. Conclusion. An integral indicator, which characterizes the severity of the relief of the crown of the tooth is proposed. It was calculated as the ratio of the area of the occlusal surface to the area of the coronal surface of the tooth, taking into account the number of main and additional odontomer modules and the degree of their differentiation.

Key words:
