The effect of the growth pattern on the Bolton rate and Ark width in Orthodontic irregularitiesGökhan Pre-Age, Ismigül Sali, Wealth Born Ege University Faculty of Dentistry, Orthodontic Main Science Department, Izmir FUNCTION: The aim of this study is to determine the relationship between the growth pattern between Orthodontic patients with different malocluzions,Dental size incompatibilities and Ark widths using 3D digital work models. Methods: This study included 225 untreated Turkish patients in the university clinic in the beginning of the orthodontic records. Patients are divided into 3 main groups (class I, class II, class III) according to the sagittal assessment based on the ANB perspective. Each group consists of 75 patients and is divided into 3 subgroups according to the vertical assessment based on SnGoGN, Jarabak and BJörk angles (normodiverjan, hypodiverjan, hyperiverjan). Models are obtained by scanning digitally and using the 'Ortomodel' software program. For Bolton, the front ratio, the upper and lower ark, the front and rear ark widths are calculated using the 'Ortomodel' program. The two-way variance analysis (ANOVA) has been used to evaluate the data between groups. BULGULAR: In this sample group of Turkish orthodontic patients, the prevalence of all and front tooth size disorders is 18% and 16.9%. In Class I patients with normodiverjan growth paternine, Bolton and anterior rates were higher (p<0,05). In the hypodiverjan group, the Bolton ratio was more found in women (p<0,05). In class II patients, the Bolton rate was seen to be higher in the hypodivergen group (p<0,05). In Class III cases, the previous ratio was higher in the hyperdivergen group (p<0,05). The gender-based arc widths in men were higher than in women (p<0,05). The result is that the sagittal and vertical growth paternis are effective on the dimensions of the tooth incompatibilities.
