“…Intergroup differences were found in individuals with class II occlusion pathology using cephalometric analysis, which can be used to predict dental and skeletal parameters related to the inclination of the front teeth. As the proclination of the incisors decreased, the gonial angle significantly decreased (0.04<p<0.002), while the incisor angle, the total length of the lower jaw, and the nasolabial angle increased (0.04<p<0.001) [19].…”

Annotation. The construction of a correct orthodontic intervention that will satisfy the aesthetic and functional needs of the patient requires the perception of the craniofacial region as a single complex. At the same time, it is necessary to understand the relationship of each component of this complex and its influence on each other in order to better predict the expected result of treatment and its planning. The purpose of this study is to review modern scientific sources devoted to the study of the relationship between odontometric and cephalometric indicators. For this, a search for literary sources related to the research topic in the period 2012-2022 was performed on the basis of Google Scholar using keywords and inclusion/exclusion criteria, in particular, the presence of previous review of articles, the representativeness of the sample, and the presence of statistical analysis of the obtained data. The analysis of selected literary sources showed that the vast majority of publications are devoted to the topic of studying the relationship of odontometric and cephalometric indicators under the conditions of pathology of the dental and jaw system. Also, in most sources, researchers do not prefer the use of one or two methods of cephalometric analysis of lateral teleroentgenograms, but use complex analysis methods. At the same time, scientists pay attention to its ethnicity, gender and age when drawing up a sample. Thus, taking into account the relevance of this research topic and at the same time the lack of studies aimed at determining the relationship of cephalometric and odontometric indicators under the conditions of orthognathic bite, there is a need to conduct this kind of clinical experimental study on the Ukrainian population using several of the most common methods of cephalometric analysis.

“…Although TB appliance is generally regarded as a comfortable, aesthetic and efficient treatment, 13 there are some practical challenges in clinical practice. The force exerted on the teeth during treatment inevitably results in unfavourable tooth movements, such as proclination of mandibular incisors, intrusion of premolars and molars, 14 which have the potential to obstruct the growth or advance of the mandible 15–17 . Besides, poor clinical compliance may result in a loss of control and a reduction in success and efficiency of orthodontic treatment 5 …”

IntroductionThe purpose of this study was to evaluate the therapeutic effect of modified clear Twin Block (CTB) aligner and traditional twin block (TB) appliance from skeletal, dentoalveolar and soft tissue changes in adolescents with skeletal class II malocclusion.MethodsA total of 80 adolescents, included in this study from two medical centres, were distributed into CTB group, TB group and control group based on the treatment they received. Lateral cephalograms at pre‐treatment (T1) and post‐treatment (T2) were measured by modified Pancherz's cephalometric analysis, and dentoskeletal and soft tissue changes were analysed by independent‐sample t‐test, paired‐sample t‐test, ANOVA test and Scheffe's Post Hoc test.ResultsSeventy‐five adolescents completed the study, including 32 in the CTB group, 32 in the TB group and 11 in the control group. Both CTB and TB treatment showed significant differences in most dentoskeletal and soft tissue measurements. Compared with the control group, improvements were observed in class II molar relationship through significant different in S Vert/Ms‐S Vert/Mi in the CTB group (P < .01) and the TB group (P < .001), as well as deep overjet through significant different in S Vert/Is‐S Vert/Ii in the CTB group (P < .001) and the TB group (P < .001). Besides, the CTB group also showed less protrusion of lower incisors and resulted in a more significant improvement in profile with fewer adverse effects on speaking, eating and social activities.ConclusionsFor adolescents with skeletal class II malocclusion, CTB appliance was as effective as TB on improving dentoskeletal and soft tissue measurements, featuring more reliable teeth control and patient acceptance.

“…5 The incisors in Class II/division 1 malocclusion have significantly higher inclination angles. 6 The interincisal angle defines the mutual axial inclination of the upper and lower incisors. It is assumed that this angle should ideally be 129-132°.…”

Wprowadzenie. Zęby wychylone doprzedsionkowo stanowią problem estetyczny i biomechaniczny. Czy odbudowa protetyczna zniszczonego zęba siecznego, którego korzeń jest wychylony dowargowo sprosta siłom żucia? Cel pracy. Celem pracy była ocena wpływu wychylenia osi zębów przednich na wytrzymałość siekaczy odbudowanych wkładami koronowo-korzeniowymi. Materiał i metody. Badanie przeprowadzono metodą elementów skończonych z użyciem elementów kontaktowych. Stworzono modele 3-D zęba siecznego przyśrodkowego szczęki: model A-ząb; model B-ząb z wkładem i koroną. Osie modeli siekaczy A i B zostały ustawione 1-dopodniebiennie (kąt inklinacji 10°), 2-prawidłowo (kąt inklinacji 30°); 3-dowargowo (kąt inklinacji 50°). Każdy model obciążono siłą 100N. Do oceny wytężenia struktur zębów i cementu zastosowano zmodyfikowane kryterium Misesa.
