Specially tore medial incisors in people with different types of dental arches according to the analysis of cone-beam computed tomograms

Relevance. So far, little information is largest angle inklinacii medial cutters received from people with different types of facial and dental arches. Aim. Defining features of the tongue medial values of both jaws incisor with different gnathic and facial types dental cone beam analysis computer tomograms. Materials and methods. The study was conducted at 146 people with physiological occlusion. Patients were divided into 9 groups, depending on the type of gnathic dental arches (meso-, brachi- and dolihognathic) and dental index (normal, macro and micro dental). Gnathic type of person was determined by morphometric parameters, namely face diagonals between the points tragion and subnasale (t-sn). Face width measured between the points of tragion (t-t). Results. In a study of patients with 9 forms dental arches allocated 3 main options of slope of incisors, appropriate generally accepted in orthodontics tongue values: standard, high and low. Found that the mean values of the upper incisors medial tongue accounted for 12.36 ± 2.23 degrees. At high values of the numeric values increased to 24.29 ±2.18 degrees, and at low-declined to 5. 73 ± 2. 25 degrees. When this shows the magnitude of the angle between the incisors and torka lower incisors. Conclusion. The data obtained maybe used when selecting the constructional features of bracket systems used to treat people with different types of facial and dental occlusion anomalies systems. In addition, these data can be useful in the treatment of artificial teeth and dental implants when choosing a prosthetic designs.
