Background: Optimal management of hypodivergent growing patients demands a strict control of vertical dimension and to exploit the growth potential. If a deep bite malocclusion causes a traumatic contact between the upper and lower incisors and affects the facial appearance, an early interceptive treatment is recommended. The aim of this case report is to outline the clinical management of the occlusal plane of a growing Class II division 1 deep bite patient treated with aligners and Class II elastics. Methods: The treatment lasted 11 months and was divided into two phases. Treatment goals included improvement of the soft tissue profile and basal bone relationships through an increase in the mandibular third of the face and a sagittal advancement of the mandible. The correction of the curve of Spee involved intrusion of the mandibular incisors and extrusion of the mandibular premolars. Results: The cephalometric analysis at the end of the treatment displayed significant differences in the skeletal and occlusal pattern along with aesthetic improvements. Conclusion: The final cephalogram showed a consistency between the planned tooth movement and the clinical results. Although definitive recommendations must be withheld until longer follow-up is available, the patient presented here shows that the treatment protocol yielded positive mandibular growth.

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.

INTRODUCTION: This article demonstrates the description and use of a new appliance for Class II correction. MATERIAL AND METHODS: A case report of a 10-year 5 month-old girl who presented with a skeletally-based Class II division 1 malocclusion (ANB = 6.5º) on a slightly low-angle pattern, with ML-NSL angle of 30º and ML-NL angle of 22.5º. Overjet was increased (7 mm) and associated with a deep bite. RESULTS: Overjet and overbite reduction was undertaken with the new appliance, Fixed Lingual Mandibular Growth Modificator (FLMGM). CONCLUSION: FLMGM may be effective in stimulating the growth of the mandible and correcting skeletal Class II malocclusions. Clinicians can benefit from the unique clinical advantages that FLMGM provides, such as easy handling and full integration with bracketed appliance at any phase.

ABSTRACTObjectives: The purpose of this study was to evaluate the short-term dentoalveolar and soft tissue changes in late adolescent patients treated with the ForsusTM FRD. Methods: A prospective study was carried out on 54 lateral cephalometric radiograms that were taken before placement and after removal of the appliance in the treatment group (15 subjects) and at the beginning and six months after in the control group (12 subjects). The patient selection criteria were as follows: skeletal and dental Class II malocclusion due to retrognatic mandible, normal or low-angle growth pattern, post-peak growth period, no extracted or congenitally missing permanent teeth, and minimum crowding in the lower dental arch. Results: The statistical assesment of the data suggested the following results: No sagital and vertical skeletal changes were induced. The mandibular incisors were protruded and intruded, while the maxillary incisors were retruded and extruded. The occlusal plane was rotated in clockwise direction as a result of these dentoalveolar changes. Overbite and overjet were reduced in all patients. Soft tissue profile slightly improved. Conclusions: The results revealed that, in late-adolescent patients ForsusTM FRD corrected Class II discrepancies through maxillary and mandibular dentoalveolar changes. (Eur J Dent 2011;5:423-432)

Inter-arch elastics and reverse curve arch wire can be used successfully in the treatment of deep bite malocclusions and are two of the most common methods available for treating class II malocclusions . Careful diagnosis and treatment planning is primordial for choosing the right treatment modality which can vary from patient to patient. The subject treated in this study was a 14 years old female patient with a Class II division 2 Angle’s malocclusion having a skeletal deep bite of around 6 mm and an overjet of 1.5mm, deep curve of spee, coinciding upper and lower arch midlines with that of the facial midline. After analysis made, the case was treated without any extraction due to the fact that she was a low mandibular angle patient with minimal amount of crowding in both the arches and also a Combination Factor of 171.5° (greater than 155.9°) which represents the balance of both the vertical and horizontal dimensions. The Anterior Posterior Dysplasia Indicator value fell within the normal range indicating a Class I horizontal maxillo-mandibular relationship. The duration of the treatment was around 20 months. After achieving the goals of the treatment, cephalogram was taken and the pre and post treatment variables compared. The correction of the deep overbite condition was achieved successfully along with the correction of the molar relationship into a Class I malocclusion. U1-SN has increased by 50.0 and L1-NA increased by 4.50 together with a decrease in the inter-incisal angle by 8.50 contributing to a decrease in bite depth. The assessment of the cephalometric findings showed that the lower anterior facial height change was minimal but not insignificant partly due to the continued growth of the mandible which can be confirmed through the values of FMA which shows an increase in 20.0, Facial Height Index dropping from 0.89 to 0.88 and the TPFH:TAFH values decreasing by 0.8%. But this change was not enough to have a positive impact on the facial appearance of the subject. Change in the molar relationship was aided by the use of inter-arch elastics and the deep bite correction facilitated by the slight rotation of the occlusal plane caused by extrusion of lower first molar along with the flaring of the lower incisors induced through the use of the reverse curve arch wire. So it was confirmed that the combined use of inter arch elastics & reverse curve arch wire help to correct the class II division 2 malocclusion along with some improvement for increasing the lower anterior facial height.

This article describes our treatment of Class II, division 2 adult patients requiring premolar extractions. Division 2 cases are often characterized by severe deep bites, lingually inclined upper central and lower incisors, and labially flared maxillary lateral incisors. This patients also tend to exhibit problems with the upper and lower occlusal planes, such as deep curves of Spee, High lip line, marked labiomental depression. Because of the deep bite and supra eruption of the maxillary incisors, the gingival margins of the maxillary anterior teeth are malaligned, and the lingually inclined mandibular incisors have excessively high gingival margins ( Fig. 1 ). The treatment protocol for this patients includes extraction of premolars both upper and lower in right side to relieve crowding, with simultaneous correction of the deep bite by intrusion of the upper and/or lower incisors. Intrusion mechanics are performed with a bite opening bend on a preformed nickel titanium arch wire. Space closure is accomplished with power chain and guard behind the extracted site in anchor plate. Extraction of upper premolar and lower 1st molar (tooth no 36) in left side was done earlier. A 21 years old women with Cl-II Div-II malocclusion type B came to Dental Centre, Dhaka, with chief complaint of an unhappy smile. Retroclined 4 Incisors, Deep bite, Crowding, deficient lower facial height, Gummy smile and a moderately convex hard- and soft-tissue profile because of a retrusive mandible with over jet of 1.5mm and over bite of 6 mm was observed. The mechanics plan should be individualized based on the specific treatment goals. Camouflage Treatment was done with the help of an anchor plate incorporated anterior incline plane. Intrusion mechanics are performed with preformed nickel titanium Connecticut Intrusion Arch (CIA) and anchor plate incorporated bite plane. Treatment was successfully completed with extractions of both pre-molars in right side and left lower 1st molar (Tooth no 36) and upper 1st premolar(Tooth no 24) already extracted ( Fig. 2 A) before starting of orthodontic treatment. Treatment of 20 months which improves incisor inclination, Deep bite correction; eliminate crowding, normal smile line and improvement of gummy smile. With the above mentioned protocol normal inclination of both upper-lower incisor, normal over jet and over bite were also achieved.

The most prevalent malocclusion seen in day-to-day practice is Class II division 1 malocclusion. Most patients with malocclusions in class II division 1 have an underlying skeletal difference between the maxilla and the mandible. The treatment of skeletal class II division 1 depends on the patient's age, the ability of growth potential, the seriousness of malocclusion, and the patient's adherence to treatment. Myofunctional equipment can be successfully used to treat rising patients with deficient mandible class II division 1 malocclusion. This case report shows a focus on Class II Division 1 care due to mandibular deficiency using modified bionator appliances accompanied by fixed mechanotherapy with growth modification approach. Class II Division 1 is one of the most widely encountered form of malocclusion in human populations. The common characteristic of Class II Div 1 malocclusion in growing children is mandibular retrusion, according to Dr. James McNamara.1 The prevalence of Skeletal Class II malocclusion is 15 % of the world's total population. Underlying difference between Maxillary & Mandibular jaw makes the Class II Div 1 malocclusion more complex than it appears. It’s due to a contribution of only maxilla, or only mandible, or a combination of both. The treatment of Class II division 1 relies on the patient's age, growth ability, degree of malocclusion, and patient compliance with therapy.1,2 The cases with retrognathic mandible must be addressed by altering the direction & amount of mandibular growth by using functional appliances.3 The Bionator is a tooth-borne appliance that significantly changes dental and skeletal component of the face through a repositioning of mandible in a more protrusive & balanced way, selective eruption of teeth and profile enhancement.4-7 The Balters Bionator was first introduced in 1960 by Wilhelm Balters as a functional appliance & still one of the most widely used removable appliances for correction of mandibular retrognathism.8 In functional orthopaedics, all aspects of genetically determined individual growth patterns are important, most particularly time, potential, and growth direction. Although during the prepubertal phase there is limited skeletal development, substantial growth occurs during puberty, but with great individual variation. To prevent damage to erupting teeth and to normalize jaw growth, early functional orthopaedic intervention in the prepubertal phase is used.9,10,11 The purpose of this case report is to illustrate how satisfactory results were obtained in the treatment of Class II division 1 malocclusion with modified Bionator in young patients. The positive facial, dental and cephalometric improvements are also illustrated, with the aid of proper diagnosis, amplified by excellent patient cooperation in case selection.
