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.

Abstract BackgroundThe objective of this study was to identify the soft tissue profile outcomes of orthodontic treatment of Class II, division 1 malocclusion patients and to determine if these changes are related with different treatment protocol.MethodsThe sample of this study consisted of 50 Caucasian patients [22 males; 28 females], with a mean age of 15.8 years. The sample was divided in two groups (both groups treated with multibracket therapy): first group was non-extraction group [25 patients] treated first with the Herbst appliance, and second group was four premolars extraction group [25 patients] treated with a multibracket appliance. The patients’ pre- and post-treatment profile photographs were used, and the soft tissue landmarks were identified. Afterwards, the angular parameters were determined on each photo. Paired-sample t-test was used for intragroup comparisons. For testing the differences in all parameter values between groups, two-sample t test was used.ResultsThe improvement in the non-extraction group was evident in the decrease of the nasomental angle [P=0.02], the angle representing the projection of the upper lip to the chin [P=0.01], as well as the upper lip angle [P=0.01]. On the other hand, the nasolabial angle increased significantly [P=0.01], as well as the mentolabial angle [P=0.02]. In the extraction group, the nasolabial angle showed a significant increase [P=0.03]. Two soft tissue variables showed significant differences between the groups: the total facial angle or facial convexity including the nose [P=0.04] and the angle presenting the projection of the upper lip to chin [P=0.01].ConclusionsThe patients treated without extractions showed a significant improvement of the convex profile and favorable soft tissue changes in the lower third of the face. The orthodontic treatment of Class II, division 1 malocclusions induce positive effects on the soft tissue facial profile, which depends on different treatment protocols.

Introduction: Twin-block appliance is simple removable bite block mostly used in the management of Class II malocclusion. It can modify the occlusal inclined plane to guide the mandible protrusion. Hence, when the patients are wearing the Twin-block appliances, this altered biomechanical environment and will stimulate the growth of the secondary cartilage of condyle and will caused the condyle to change in size, volume or position the in long term. The aim of this study was to investigate the changes of horizontal distance from condyle to nasal septum after the Twin-block treatment on Class II division 1 with retrognathic mandible. Methods: There were total 5 samples of panoramic radiograph before Twin-block treatment and 5 samples of panoramic radiograph after Twin-block treatment. The panoramic radiographs were traced to identify the changes of horizontal distance from condyle to nasal septum after the Twin-block treatment. The distance from the middle of nasal septum to the most superior surface of condyle head for right region and left region were measured, then the differences were statistically analyzed. Results: The horizontal distance from the middle of nasal septum to the most superior surface of condyle head after the Twin-block treatment increased. The difference of condyle position before and after the treatment of Twin-block.was slight (p-value > 0.05). Conclusion: There is no significant difference in horizontal distance from the most superior surface of condyle head to the middle of nasal septum before and after treatment of Twin-block.

ABSTRACT Background Prevalence of malocclusion varies in different parts of a diverse country like India. Aims To determine the prevalence of malocclusion in population of Jaipur city, Rajasthan, India, as well as subjects views regarding the most important factor for seeking orthodontic treatment by patients who have malocclusion. Materials and methods The sample consisted of 700 subjects (373 males and 327 females) with age group of 15 to 30 years. Subjects were randomly selected and none of them had received orthodontic treatment previously. The subjects who showed bilateral Angle's class I molar relationship with acceptable overjet, overbite and well-aligned arches or minimal crowding were considered to have normal occlusion. The subjects with malocclusion were classified into four groups according to Angle's classification, i.e. class I, class II division 1, class II division 2 and class III malocclusions. Results About 74.57% of population was found to have malocclusion. Among these subjects, 52.57% subjects were diagnosed with class I malocclusion, 12.57% with class II division 1 malocclusion, 8% with class II division 2 and remaining 1.42% had class III malocclusion. No statistically significant differences were found between male and female subjects. Conclusion Among class I malocclusion characteristics, Angle's class I type 1 malocclusion was statistically significantly found to be the most prevalent type of malocclusion. As far as the most important factor for seeking orthodontic treatment was determined, a desire of enhancing facial appearance followed by a desire of attaining straight teeth was considered to be the chief motivational factor among this population.

Introduction: Class II div 1 malocclusion is most commonly presented with retruded mandible. This backward placement of mandible pushes the tongue posteriorly and inturn impairs the position of hyoid bone and total tongue area. Correction of retruded mandible with functional appliances is also considered to have positive effect on hyoid bone position and tongue area. Aim and Objectives: The objective of this study was to evaluate and compare the effects of Twin Block and Forsus on the hyoid bone position and tongue area in the treatment of Class II division 1 malocclusion. Materials & Method: A 2-arm parallel, randomized controlled trial was designed consisting of 24 Class II division 1 malocclusion patients indicated for treatment with functional appliances. 24 patients were randomized and equally divided among Twin Block (Group A) and Forsus (Group B) group. Pre- and post functional lateral cephalograms of both groups were traced and statistically analysed using paired t-test and T test of Equality of Means. ‘p’ value of less than 0.05 was considered as statistically significant. Result: A significantly upward and forward movement of hyoid bone was found with both the appliances. Tongue area also improved with Twin Block and Forsus group. On intergroup comparison insignificant results were observed between both the appliances indicating similar effect on tongue area and hyoid bone position. Conclusion: Twin Block has more skeletal effect than Forsus, still both Twin Block and Forsus are effective in improving tongue area and forward and upward displacement of hyoid bone position while correcting Class II malocclusion.

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.
