[Functional research methods in the diagnosis of traumatic over- and underloading of the teeth].

Rheography and step-type discriminant analysis were used to examine rheographic characteristics of periodontal hemodynamics in 80 patients with primary traumatic occlusion and periodontitis-complicated traumatic occlusion. Mathematical models of the conditions were created, that may be used in practical orthodontics for the differential diagnosis, prediction of the results, and purposeful treatment of patients with traumatic overexercise of the teeth. The share of correctly classified cases for the differential diagnosis with the use of mathematical methods turned to be high--88.3%. The reliability of periodontal hemodynamics parameters for the diagnosis of traumatic overexercise of the teeth is 99.9%.
