“…The said angles are typically determined by the individual characteristics of facial types and types of dental arches. For certain types of dental arches, the normal position of the incisors is retrusive, for the others, on the contrary, it is the protrusive position [35][36][37][38][39]. Given that, still relevant are the issues implying developing methods that allow improving the accuracy of measurements and determining the position of the joint elements and the incisors, which is of particular importance in clinical orthodontics when it comes to forecasting and evaluating the treatment effectiveness.…”

This work reveals the analysis outcomes for craniometric and morphometric parameters of the temporomandibular joints and incisal dentofacial segments obtained through studying 157 computer tomograms and lateral skull teleradiographies from people with physiological occlusion of permanent teeth in the first mature age period. Detailed investigation of the spatial arrangement of the craniofacial structures allowed developing, substantiating and testing a method of computer tomograms combination of the mandibular joint and dentofacial segments of the mandibular and maxillary medial incisors with head teleradiographies in the lateral projection. This algorithm allowed increasing the measurements reliability (linear, angular) in the sagittal plane, identifying the degree of complexity and justifying the choice of tactics for the planned treatment, describing the facial skull growth type (horizontal, vertical and neutral), as well as evaluating the effectiveness of orthodontic treatment at all stages.

Aim. To determine the link between the clinical and radiological torque of the medial incisors in cases with physiological occlusion. Materials and methods. A measurement of the clinical torque values was performed (whereas the torque is defined as the deviation of the tooth crown vestibular surface from the occlusal plane) in 98 people with physiological occlusion and a full set of permanent teeth. When measuring the clinical incisor torque, three methods were employed. The first method allowed studying teeth torque in relation to the occlusal plane on the cast jaw models using the ArcoZet equipment (by Scheu Dental GmbH). The second method implied using a modified protractor, where the moving part was oriented in relation to the occlusal plane. The third method we used involved analyzing data from teleradiography and cone-beam tomograms obtained with the PaX-i3D SC digital panoramic X-ray unit (VATECH Global), which were marked with linear and angular reference points. The patients were divided into three groups depending on the incisors location: Group 1 included patients with the mesotrusive incisors location; Group 2 were patients with physiological protrusion of the incisors and a decrease in the interincisal angle, with Group 3 including patients with physiological retrusion of incisors. Results. Regardless of the type of dental arches and the vestibular lingual inclination of the incisors, the average difference between the clinical and the radiological incisor torque values is 26°, which can be used in clinical orthodontics to develop a treatment tactics and its effectiveness in people with various gnathic and dental types as well as with various dental arches. Conclusion. All methods used for measuring the teeth inclination angles in the vestibular lingual direction can be employed both in the applied and in the clinical aspect. Identifying the permanent teeth torque through cast models of dentition morphometry and through using special equipment, takes a lot of effort, time, at the same time being subject to potential measurement errors. The methods implying analysis of cone-beam computed tomography images feature high-tech reliance, precision, whereas the reproductive capacity and interpretation of the results allows using the available angular and linear parameters for evaluating the effectiveness of the respective orthodontic procedures through all the stages of treatment

Biometric examinations of jaw stone models and tomography images of 310 people (both genders) in their first adulthood stage with permanent teeth physiological occlusion were used to study the morphometric parameters of dental types and dental arches gnathic types in each patient. Odontometric procedure included evaluation of the crowns mesial-distal width involving the calculation of the arithmetic mean, the maximum and the minimum values, in order to estimate the deviations from the mean value (fluctuation). The outcomes suggest that there was no statistically significant difference between the odontometric parameters obtained from men and women. The significant variability in the frontal teeth size in women, compared with men, indicates that the size is only slightly dependent on gender, while is determined by the dental system type. In measurements done without taking into account the dental type, it can be hard to determine sexual dimorphism due to the fluctuating nature of the odontometric indices.
