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%.
采用血流图法和逐步判别分析法，对80例原发性创伤性咬合及牙周炎合并创伤性咬合患者的牙周血流动力学的血流图特征进行了研究。建立了这些情况的数学模型，可用于实际正畸中对牙齿创伤性过度行使功能患者的鉴别诊断、结果预测和针对性治疗。采用数学方法进行鉴别诊断时，正确分类病例的比例很高——88.3%。牙周血流动力学参数对牙齿创伤性过度行使功能诊断的可靠性为99.9%。
