Aim: The purpose of this retrospective study was to investigate the effects of phase 2 with fixed appliances, after phase 1 Bionator treatment of Class II division 1 malocclusion, as compared to a matching control group. Methods: The experimental group consisted of 20 patients who were evaluated after orthodontic treatment with fixed appliances subsequently to functional therapy with the Bionator in phase 1.  A control group consisting of 20 Class II, division 1 individuals. Results: During phase 1 there was significant forward growth restriction in the maxillary complex, improvement of the maxillomandibular relationship and decrease in facial convexity.  There was also significant reduction of the maxillary incisor proclination and protrusion, protrusion of the mandibular incisors, and vertical development of the mandibular molars.  The overjet was significantly reduced and the molar relationship was significantly improved.  Treatment during phase 2, with fixed appliances, resulted in significant maxillary forward growth restriction and facial convexity reduction. Conclusion:  Major Class II skeletal and dentoalveolar anteroposterior correction was obtained during phase 1, with the Bionator.  Phase 2, with fixed appliances only produced a significant maxillary forward growth restriction and facial convexity reduction, without any significant dentoalveolar change.

Abstract Objective: To evaluate the morphological changes in the lips and to determine the degree of improvement in the smile after orthodontic treatment for Class II division 1 malocclusion. Materials and Methods: The sample subjects were divided into two groups: a group that consisted of 20 adult female patients with Angle Class II division 1 malocclusion and a control group that consisted of 28 adult female volunteers with normal occlusion. Frontal photographs were taken before and after orthodontic treatment, and 35 landmarks were placed on each tracing made from the photograph. Thereafter, landmarks were digitized into an x- and y-coordinate system with the subnasal point as the origin. The comparisons between pretreatment and posttreatment at rest and on smiling, and the comparisons between Class II division 1 and control group were made using Student's t-test. Results: Both the upper and lower lips in the smile of patients in the Class II division 1 pretreatment group were positioned downward, and the upward movement of the upper lip and mouth corners was smaller in comparison with the control group. These characteristics of the Class II smile improved after orthodontic treatment, but the differences with the control group remained unchanged immediately after treatment. Conclusion: The soft tissue morphology shows a relative improvement after orthodontic treatment.

Introduction: Orthodontic treatment of class II division 1 malocclusion by extracting the maxillary first premolar causes vertical dimensional change is still a matter of debate. The purpose of this research was to determine the vertical changes of the lower anterior facial height and maxillary incisor vertical dimensions in class II division 1 malocclusion after orthodontic treatment with Edgewise technique. Materials and Methods: This study was conducted on the cephalometry of 24 patients before and after orthodontic treatment with inclusion criteria as follows: Angle Class II division 1  malocclusion, aged 18-30 years old. Measurements were taken for the lower anterior facial height (ANS - Me) and maxillary incisor vertical dimensions by performing an Upper Anterior Dental Height (UADH). Data analysis used was the Wilcoxon test for unpaired data. Results: The result of p-value = 0.195 > 0.05 for lower anterior face height showed no significant difference; and p-value = 0.878 > 0.05 for UADH also showed no significant difference. Conclusion: Orthodontic treatment for class II division 1 malocclusion with the removal of two premolars does not change the lower anterior facial height and maxillary incisor vertical dimensions.

Association of tongue posture with dental and facial skeletal pattern have been suggested in past. This study was undertaken to assess tongue posture and dimensions in Class I and Class II Dentoskeletal patterns to determine whether any correlation exists between tongue posture and skeletal pattern of an individual. Cephalograms of 150 individuals (aged 18-23 years), taken in Natural Head Position (NHP) and tongue at rest were divided into three groups i.e. Group 1 – Class I Normal occlusion, Group 2 – Class II Division 1 Normodivergent and Group 3 – Class II Division 1 Hypodivergent, consisting of 50 samples each. To ensure the rest position of tongue, patient was asked to relax for 30 seconds after coating the tongue with barium sulphate in midline and then to swallow, and the X-ray was taken at the end of swallowing. Each group was divided into two subgroups according to sex. Groups were constituted according to the Frankfort mandibular plane angle (FMA) angle. The subjects who had skeletal Class II pattern due to mandibular retrusion and not due to maxillary prognathism were only included in the study group. Statistical analysis was done using the software SPSS version 21.0. The statistical tests used were unpaired t-test and One-way ANOVA test with post-hoc bonferroni test. The p-value was considered significant if less than 0.05.The dorsum of the tongue was higher at back and lower in front in Class II Division 1 Hypodivergent group as compared to Class I Normal occlusion group (P<.05). Tongue height and tongue length were significantly reduced in Class II Division 1 Normodivergent and Class II Division 1 Hypodivergent malocclusion groups when compared to Class I control group (P<.05).The study supports the existence of a relationship between posture & dimensions of the tongue with Class I and Class II skeletal patterns.

Introduction. Orthodontic treatment of Class II Division 1 (II/1) malocclusions in adults can be challenging since skeletal effects are limited. Possible treatment options are orthodontic camouflage or orthognatic surgery, in severe cases. The aim of this paper was to present a successful management of Class II malocclusion in an adult patient using temporary anchorage devices (TADs). Case report. After detailed clinical examination, study models and cephalometric analysis, a 26 years old patient was diagnosed with Class II malocclusion, an overjet of 12 mm, congenitally missing tooth 41 and midline shifted to the right in upper dental arch. In prior orthodontic treatment, patient had upper premolars extracted. Posterior teeth in upper left quadrant were shifted mesially. The camouflage treatment was considered, using temporary anchorage devices (TADs) to distalize posterior teeth on the left side, and gain space for incisor retraction and midline correction in upper dental arch. Results. Using TADs as additional anchorage in anterior region and coil spring for molar distalization, the space was made for tooth 23, midline correction and incisor retraction. After 40 months, a satisfactory result was achieved, overjet and midline correction, class I canines occlusion and class II molar occlusion. Conclusion. Class II/1 malocclusion in adults can be successfully treated using TADs. The success depends on the severity of malocclusion and patient cooperation.

The orthodontic treatment of severe class II division 1 malocclusions is often difficult, which leads some specialists to offer a surgical correction of the overjet. Treatment is made complex by the value of the horizontal overlap as much as the « depth » of deep bite that is very often present alongside the malocclusion. This is why we are offering a treatment protocol including a FABP (Fixed Anterior Bite Plate) which will allow, if the patient cooperates, to correct the anatomic anomaly while concurrently establishing new masticatory cycles in order to stabilize and preserve the results obtained. It is this systemic approach of treatment that is the focus of this article.

ABSTRACTObjectives: The aim of this study was to investigate the alveolar and symphysis region properties in hyper-, hypo-, and normodivergent Class II division 1 anomaliesMethods: Pretreatment lateral cephalograms of 111 young adult female patients with skeletal Class II division 1 anomalies were compared to those of 54 Class I normal subjects (control group). Class II cases were divided into hyperdivergent (n = 58), hypodivergent (n = 19), and normodivergent groups (n = 34). The heights and widths of the symphysis and alveolus and the depth of maxillary palate were measured on the lateral cephalogramsResults: Mean symphysis width was wider in the hypodivergent Class II group than in the other groups, while mean symphysis height was similar among all groups. Maxillary palatal depth, upper incisor angle, upper and lower molar alveolar heights, and Id–Id′ width were also similar among groupsConclusion: Symphysis width is the main factor in the differential diagnosis of Class II division 1 anomaly rather than symphysis height and hypodivergent Class II Division 1 anomaly is more suitable for mandibular incisors movements.
