“…The sample size was a crucial drawback in this research because getting a sample with normal occlusion and sound teeth is so difficult. With the development in technology and presence of special analyzing software, intraoral scanner devices, digital camera, and CBCT, it became easier to measure teeth and dental arch dimensions in three planes of space [ 36 ]. This replaces the use of conventional methods of measuring these parameters.…”

Background. The purpose of the present study was to use the combined mesiodistal crown widths of the mandibular and maxillary incisors as predictors for the combined mesiodistal crown widths of mandibular and maxillary canines and premolars. Materials and Methods. One hundred and twenty pairs of study models belong to 120 Iraqi adult subjects with normal dental and skeletal relations were included in the study. The crown widths of the mandibular and maxillary incisors, canines, and premolars were assessed at the maximum mesiodistal dimension on the dental casts using a digital electronic caliper with 0.01 mm sensitivity. The correlation between combined mesiodistal crown widths of the mandibular and the maxillary incisors and combined mesiodistal crown widths of mandibular and maxillary premolars and canines has been determined using Pearson’s coefficient correlation test for each arch and gender. Using simple regression analysis, the equations predicting the widths of the mandibular and maxillary premolars and canines were established. The predicted and the actual mesiodistal crown width values have been compared with the use of a paired sample t-test. Results. According to the findings of the present study, males had significantly wider teeth compared to females. Correlations between the measured parameters ranged from moderate to strong. A nonsignificant difference between actual and predicted mesiodistal crown widths was discovered. Conclusions. With a high degree of accuracy, the combined mesiodistal widths of the maxillary and the mandibular incisors could be utilized for predicting the combined mesiodistal crown widths of the mandibular and maxillary canines and premolars.

“…In our study, we used the double‐slot lingual bracket system. Various double‐slot bracket designs could be applied with two rectangular archwires 22 ; one round and one rectangular archwire 16 ; or two round archwires 23 . The dimensions and distances between slots vary, and a double‐slot bracket could be used in labial and lingual orthodontics, but more often in lingual brackets due to aesthetics.…”

Objective The objective of the study was to find the most effective retracting method for the six maxillary anterior teeth with double‐slot lingual brackets using a lever arm and miniscrew system. Methods Six finite element models were constructed: (A) a ribbon‐wise archwire with a lever arm; (B) a ribbon‐wise archwire with a lever arm and a sectional edgewise archwire; (C) a ribbon‐wise archwire and a sectional edgewise archwire with a lever arm; (D) an edgewise archwire with a lever arm; (E) an edgewise archwire with a lever arm and a sectional ribbon‐wise archwire; and (F) an edgewise archwire and a sectional ribbon‐wise archwire with a lever arm. Initial displacements of maxillary teeth driven by a 1.5 N retraction force to the lever arm were analysed. Results In models B, C, E and F, anterior torque loss and inter‐canine distance increases were significantly lower than that of the models without auxiliary archwires. In models C and F, the main archwire was less likely deformed. In models A, B and C, the displacement of canines in sagittal and vertical directions were less than in models D, E and F. Conclusions The combination of edgewise and ribbon‐wise archwires in double‐slot lingual brackets effectively preserves the anterior arch shape. An edgewise archwire with lever arms on the auxiliary sectional ribbon‐wise archwire is recommended for better performance in anterior teeth retraction.

Object. A cephalometric analysis was performed in children with deep distal occlusion. The aim of the study — To determine the age-related changes in the vertical parameters of the face in children with deep distal occlusion. Methodology. The article is devoted to the analysis of cephalometric parameters in patients with deep distal occlusion at different age periods in the groups: 7-9, 10-12, 13-15 years. The calculation of 15 parameters of lateral teleroentgenograms was carried out, of which 12 characterized the vertical development of the facial skeleton and the tooth-alveolar region. The analysis was performed using a computer program for automated analysis of skull radiographs. Results. The study revealed age-related changes in the parameters that characterize the vertical development of the maxillofacial region in children with deep distal occlusion. Conclusion. Changes with age in the parameters of the angles NSL/ML, NSL/NL, anterior and posterior height of the face are early signs of a genetically determined developmental anomaly. An increase in the depth of the incisal overlap with age, a deepening of the Spee occlusal line are interrelated with an increase in the tooth-alveolar height in the incisor region and with a decrease in the tooth-alveolar height in the region of the first molars, especially in the lower jaw. The sagittal position of the upper and lower incisors in distal occlusion does not change with age and corresponds to the average normal values. Established age-related changes in the parameters of the facial skeleton in deep distal occlusion make it possible to determine the area of influence of orthodontic treatment at the stages of bite development — tooth-alveolar, in the vertical plane.
