Spontaneous improvement in molar occlusion is often assumed to accompany orthodontic treatment of the Class II Division I case where all pre-molars have been removed. The investigation shows that while the buccal occlusion generally improves after the completion of removable appliance treatment this is seldom enough to correct a Class II molar relationship.

Spontaneous improvement in buccal occlusion is often assumed to accompany orthodontic treatment Where premolars have been extracted. The investigation shows that buccal occlusion cannot be relied upon to improve spontaneously during typical removable appliance treatment of Class II division 1 cases.

The aim of orthodontics treatment is normalization of teeth position in three planes, using various orthodontics appliance to reach the chepalometric standar and normal occlusion. Orthodontic treatment for dentoskeletal class II division 1 malocclusion in growing patients using myofunctional appliance may correct anteroposterior planes of mandibula. This study was a descriptive retrospective analytic study to look at the success of Orthodontic treatment for dentoskeletal class II division 1 in growing patients with myofunctional appliance using chepalometrics analysis Steiner value. The sample used in this study is chepalogram radiographic from patient with dentoskeletal class II division 1 malocclusion in growing patients before and after using myofunctional appliance in PPDGS orthodontics Clinic of Padjadjaran University. Statistic analysis were performed with pair t-test and Wilcoxon. Based on this study, it is concluded that orthodontic treatment with myofunctional appliance such as activator and twin block in growing patient with dentoskeletal class II division 1 malocclusion shows significant changes and compatibility with the normal criteria.

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.

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.

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.
