“…The issues focusing on studying human constitution features, which are the basis of clinical and anthropological area, attract both theoretical and clinical medicine, while classical anthropometric methods are perfectly complemented by advanced innovationbased research approaches, at the same time enhancing the precision and effectiveness of the obtained outcomes [1, 14,19,28,35].…”

BiometriC aPProaCH to diaGnosis and manaGement oF morPHoloGiCal CHanGes in tHe dental struCture a b s t r a C t-Clinical examinations, biometric studies of jaw diagnostic models and cone-beam computed tomography were performed involving 104 people in their first adult period with a full set of permanent teeth, the physiological occlusion and the mesognathic type of dental arches. Clinical and X-ray-morphometric explanation of the proportional parameters of the dental and alveolar triangles, taking into account the medial incisors individual position, allowed us developing, substantiating and testing a biometric diagnostic approach to treat morphological changes in the dental structure. Patients, depending on the interincisal angle, featured the mesotrusion type (interincisal angle, 130°-140°), the protrusion type (interincisal angle below 129°) and the retrusion type of the dental arches (interincisal angle above 141°). The study revealed that the distance between the central points of the dental and alveolar triangles on both jaws could be described with the trusion type of arches. The smallest distance between the peaks of the dental and alveolar triangles was to be observed in people with the retrusion type of the arches and microdontia (upper jaw, 1.5±0.07 mm; lower jaw, 0.5±0.02 mm); the average value was recorded in patients with the mesotrusion type and normodontia (upper jaw, 2.5±0.06 mm; lower jaw, 1.5±0.05 mm); the maximum distance was observed in people with the protrusion type of the arches and macrodontia (upper jaw, 3.5±0.08 mm; lower jaw, 2.5±0.07 mm). The morphometric data interpretation can be used to describe the physiological occlusion, when choosing the tactics and the methods of orthodontic treatment for patients with disturbed shape and size of the dental arches, as well as when designing artificial dental arches for patients with full or partial adentia, thus seeking to achieve a balanced articulation balance.

“…Currently, apart from the conventional anatomical and anthropometric approaches, there are also advanced high-tech research methods available, which allow proper evaluation of individual morphological features. Further research in clinical medicine is to be focused not only on the genetic predisposition in case of certain diseases observed in various morphological body constitutions, yet also on the fact that a particular body type can be viewed as a favorable factor, which may be indicative of a sufficient adjustment potential and lower likelihood of developing certain pathologies [2,7,9,11,15,18,20,24,27,32,[38][39][40].…”

Based on the data obtained through panoramic roentgenograms, cone beam computed tomograms from 297 people featuring various somatotypes, orthognathic bite, and no sign of dentoalveolar pathology, we identified the morphometric parameters for the temporal bone mandibular (articular) fossa, and for the lower jaw head, followed with calculation of index values and the temporomandibular joint temporal congruent index. Depending on the linear and index values of the articular fossa, the patients were diagnosed with a brachio-, mesoand dolichotemporal type of the temporomandibular joint. The articular fossa index value (48.59 ± 1.82%) of the mesotemporal type indicates a double prevalence of the anterio-posterior parameter over the vertical one; a decrease in the index down to 35.29 ± 1.74% for the brachytemporal type means a more significant reduction in the articular fossa vertical size (long and low); an increase in the index up to 56.65 ± 2.12% of the dolichotemporal type points at an increase in the articular fossa vertical parameters (short and high). Regardless of the articular fossa type, in case of the orthognathic bite, the lower jaw head has been proven to occupy no more than 56.33% of the temporomandibular joint volume, evidence to that being the congruency index value. Analysis of constitutional types suggests the predominance of patients with the asthenic type of physique (56.6 ± 4.3%) over those with a normosthenic (27.3% + 2.9%) and a hypersthenic ones (16.1 ± 2.3%). Further study of the issues related to the temporomandibular joint individual variability in people with different types of body constitution will allow customizing the approach to therapy & prevention measures, as well as it would make help predict the treatment outcomes for patients with muscle & joint dysfunction.

Based on the data obtained through panoramic radiograph analysis and cone-beam computed tomograms involving 213 patients (21-35 y.o.) featuring physiological occlusion and various gnathic and dental types of dental arches, a method has been developed to allow identifying the index of temporomandibular joints' articular fossae, taken as the ratio of the sagittal and the vertical sizes. The study revealed that in case of physiological occlusion there are three major types of the temporal bone articular fossa to be identified: dolichotemporal-short and high; brachytemporal-long and low; mesotemporal-proportional. It has been proven that with different physiological occlusions, the average type of the articular fossa is typical of those with mesognathic normodontic, brachygnathic macrodontic, and dolichognathic microdontic dental arches, while the articular fossa index is 1.84±0.21, 1.74±0.13 and 1.82±0.24, respectively. The systematization of the data from morphometric studies suggests that in case of physiological retrusion, the articular fossa value index is significantly lower compared to the average type of the articular fossa, whereas it is statistically higher in case we observe protrusion.
