Impact of functional orthodontic treatment on facial attractiveness of children with Class II division 1 malocclusion

Summary Background/objectives Whether orthodontic treatment with functional appliances improves facial aesthetics is still under debate. This study aimed to determine whether functional orthodontic treatment improves the facial attractiveness of patients with Class II division 1 malocclusion. Materials/method Extraoral lateral photographs of 20 children with Class I (CLI, 11.7 ± 0.8 years), and before (T1) and after treatment (T2) photographs of patients with Class II division 1 (CLII T1 and CLII T2; mean age ± SD = 11.1 ± 0.6 years) treated with functional appliances, were transformed into black silhouettes. Three panels of examiners including 30 orthodontists (39.0 ± 10.1 years), 30 dentists (40.0 ± 9.7) and 30 laypersons (39.0 ± 9.2) evaluated the attractiveness of patients’ silhouettes using a 100-mm visual analogue scale, and the sagittal position of patients’ upper lip, lower lip, and chin using a 3-point Likert scale. Two-way ANOVA and a chi-square test were used to test differences among groups. Statistically significance was set as P < 0.05. Results The silhouettes of CLII T2 individuals were more attractive than those of the other groups (all Ps < 0.001). The upper lip, lower lip, and the chin of these individuals were judged to be normally positioned in 69.5 per cent, 74.9 per cent, and 72.3 per cent of the assessments, respectively (all Ps < 0.05). Limitations This study did not account for the psychological profile of the examiners, which may have affected the ratings. Conclusions/implications Orthodontic treatment with functional appliances is associated with a superior facial profile attractiveness. Functional treatment should be considered as a treatment option to improve the facial appearance of children with Class II division 1 malocclusion.

OBJECTIVE: This study assessed the anterior-posterior positioning of the upper and lower first molars, and the degree of rotation of the upper first molars in individuals with Class II, division 1, malocclusion. METHODS: Asymmetry I, an accurate device, was used to assess sixty sets of dental casts from 27 females and 33 males, aged between 12 and 21 years old, with bilateral Class II, division 1. The sagittal position of the molars was determined by positioning the casts onto the device, considering the midpalatal suture as a symmetry reference, and then measuring the distance between the mesial marginal ridge of the most distal molar and the mesial marginal ridge of its counterpart. With regard to the degree of rotation of the upper molar, the distance between landmarks on the mesial marginal ridge was measured. Chi-square test with a 5% significance level was used to verify the variation in molars position. Student's t test at 5% significance was used for statistical analysis. RESULTS: A great number of lower molars mesially positioned was registered, and the comparison between the right and left sides also demonstrated a higher number of mesially positioned molars on the right side of both arches. The average rotation of the molars was found to be 0.76 mm and 0.93 mm for the right and left sides, respectively. CONCLUSION: No statistically significant difference was detected between the mean values of molars mesialization regardless of the side and arch. Molars rotation, measured in millimeters, represented ¼ of Class II.

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. Different malocclusions indicate different thickness of facial soft tissue. Objective. The aim of the study was to establish the differences in the thickness of facial soft tissue profile in persons with dentoskeletal Class II/1 and II/2 relationship. Methods. In the study we used cephalometric rendgenograms profile analysis of 60 patients aged 12-18 years of the Dental Clinic in Nis who had not previously undergone orthodontical treatment. According to the dentoskeletal jaws relations the patients were divided into two groups with Class II division 1 and Class II class division 2. In all of them the standard dentoskeletal profile analysis by Steiner and soft tissue profile analysis by Burston was done. The obtained findings were statistically analyzed and the comparison between the studied groups was performed. Results. The results indicated the following: in the patients with Class II/1 relationship there was a significantly thinner upper lip (t=5.741; p<0.0001), thinner upper lip sulcus (t=3.858; p<0.001) and significantly thinner lower lip (t=2.009; p<0.05) in relation to the patients with Class II/2. Compensatory effect in the Class II/1 patients was more distinctive in females, as their soft tissue profiles were thicker. In Class II/2 patients this relationship was in favor of males. Conclusion. The facial soft tissue profile indicated significant differences in the thickness dependant on the type of malocclusion and gender. Because of their great variability and a significant participation in the formation of the profile, while planning orthodontic therapy, it is necessary to pay them full attention, with obligatory analysis of the dentoskeletal profile.

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.

Class Ii Division 1

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.

A group of 30 general dental practitioners were asked to plan treatment for a series of 10 Class II division 1 malocclusions of graded severity. The results were assessed against a gold standard provided by three consultants. Only 14 per cent of practitioner treatment plans agreed with the gold standard and agreement was worst for those cases requiring the use of headgear. When consultants and General Dental Practitioners (GDPs) were asked whether a case should be referred for advice before the GDP began treatment, 64 per cent of GDP decisions agreed with those of the consultants. On 13 per cent of occasions, however, the GDP would have initiated incorrect treatment without seeking consultant advice.
