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.

ABSTRACT This case report describes the orthodontic and orthopedic treatment of an 18-year-old male patient who presented with prognathic maxilla, deep bite, low mandibular plane angle, and proclined incisors. Modified three-piece base arch was used for the intrusion and retraction of maxillary incisor. En masse retraction was achieved in 6 months. Reduced time for retraction was attributed to a single stage of retraction unlike Burstone three-piece intrusion base arch where canines are individually retracted followed by retraction of incisors. A modified utility arch was used in lower arch followed by a continuous archwire technique. The case was finished using bite settling elastics on a continuous archwire. The step between canine and premolar was corrected in the finishing phase of treatment. The final treatment outcomes were satisfactory and true intrusion was achieved with proper selection of biomechanics. How to cite this article Lekhadia DR, Hegde G.

Objectives: The objectives of the study were to investigate the effect of lower posterior tooth extrusion on skeletal and dental changes in Class II division 1 deep bite short-faced growing patients. Materials and Methods: Twenty-two growing patients with Class II/1 malocclusion deep bite/short-face were treated using a pre-adjusted edgewise-fixed appliance. The curve of Spee (COS) was leveled by rectangular wire and posterior vertical elastic. Two consecutive lateral cephalometric radiographs were collected before and after treatment. Changes from the cephalometric analysis were compared with 22 untreated matched subjects during the observation period with independent t-test. Results: The reduction of deep bite from the COS in the treated group was 2.83 mm which was obtained by a greater amount of posterior extrusion (1.37 mm), than anterior intrusion (0.58 mm), and lower facial height significantly increased (3.70 mm). The treated group showed significant forward mandibular position from SNB (1.36°), Pg-Nperp (1.53 mm), and the skeletal relationship improved (ANB = −0.88°). The mandibular plane angles (SN-MP and FMA) showed no significant changes during treatment. Dental changes revealed significant decreases in overjet and overbite, whereas the position and inclination of the upper and lower incisors were not significantly different. Conclusions: The increase of lower facial height in Class II deep bite short-faced growing patients was successfully accomplished by lower posterior tooth extrusion with the use of rectangular wire with posterior vertical elastic. The mandibular plane angle did not change during treatment. Class II skeletal relationship improved by the forward position of the mandible in hypo- and normodivergent pattern subjects.

Background: Class II division 1 malocclusion characterized by mandibularretrognation, deep bite and increasement of overjet. Myofunctional appliance could modify the growth and developmental of mandibular at appropriate phase. The purpose of this case report was to present successful management of Class II division 1 by using bionator and removable appliance.Case Management: A 9 years old girl with upper teeth protrusion, crowding and affected the esthetical perception. The diagnosis was Class II division 1 with mandibular retrognation and upper incisor protrusion, upper and lower anterior crowding and palatal bite. Patient also had lip biting and thumb sucking habit. Bionator leads the mandibular moved forward and arch widening. Treatment planning were to reduce overjet by prognating mandibular and bad habit elimination. Followed by retracting the upper teeth and deep bite correction by using removable appliance.Conclusion: Patient profile became corrected in 10 weeks. Overjet reduced in by prognating the mandible, decreasing of palatal bite, molar relation become Class I and bad habit elimination. In 10 months, overjet and overbite were corrected.

Introduction: Orthodontic management of cases presenting with compromised permanent first molars are difficult in aspects of treatment due to the loss of anchor teeth. Therefore, a problem-oriented approach is always preferred as an aid in treatment line. Description: In this report, we discuss a case with multiple orthodontic problems ie. Class II division 1 malocclusion, deep bite, crowding and grossly decayed first molars of all four quadrants. The management of this case was done using a modification of the MUST appliance for uprighting the lower molars and closure of molar extraction spaces. Results: The total treatment duration was 23 months and results were stable after a 1 year follow up. Conclusion: Correct diagnosis and effective biomechanics are the key to successful treatment of compromised dentition.

Abstract Objective: To describe and analyze the skeletal and dental characteristics associated with Class II division 1 (Class II/1) and Class II division 2 (Class II/2) malocclusions in the anteroposterior and vertical dimensions. Materials and Methods: A total of 551 lateral cephalograms were used; 293 films of Class II/1 and 258 films of Class II/2 malocclusions. Lateral cephalographs were traced and analyzed. Parameters for both malocclusions were compared with each other and with the norms calculated for the Jordanian population in another study. Results: The maxilla was prognathic in both malocclusions. The mandible was retrognathic in Class II/1 and orthognathic in Class II/2. Vertically, LAFH was significantly reduced in patients with Class II/2 compared with subjects with Class II/1 who exhibited a significantly increased LAFH. In Class II/1, the lower incisors were proclined and the interincisal angle was reduced, while in Class II/2 the lower incisors were at a normal inclination and the interincisal angle was significantly increased. Conclusions: Class II/2 may be considered as a separate entity which differs in almost all skeletal and dental features from Class I and Class II/1. A Class II skeletal pattern and reduced interincisal angle were common features of Class II/1 malocclusion, while a Class II skeletal pattern, increased interincisal angle, and skeletal deep bite were common features of Class II/2 malocclusion.
