Increased abrasion of the hard tissues of the teeth (PSTT) is a polyethological disease with a relatively rapid development, which is irreversible, leading to malocclusion. Goal. To analyze the changes occurring with the occlusal surfaces of the dentition in the generalized form of PSTT, depending on the type of bite and severity. Materials and methods. The condition of the hard tissues of the teeth was determined by the method of Goldberg H.G.V. (1976), according to the method of Khamitova N.H. (1986), the OCG index was calculated. Research results with an increase in the degree of erasure of the hard tissues of teeth, the values of the erasure index for all types of bite increase, reaching the highest with a straight bite, the lowest with an open bite, regardless of the type of bite, as the pathology develops, the index values for the upper jaw begin to prevail. With a generalized form of PSTT and complete dentition, the values of the OCG index approach 100%. Conclusion. There was a tendency to increase the values of the erasure and OCG indices depending on the severity of the pathological process, as well as the effect of the type of bite on their magnitude.
