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.

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.

This case report presents the treatment of a 14-year-and-8-month-old boy with Class II division 2 mandibular retrusion, severe deep bite, and concave profile. The Forsus fatigue resistance device (FRD) was effective in correcting both skeletal and dental parameters. At 5-year posttreatment follow-up, the teeth were well aligned and the occlusion was stable. FRD application with appropriate treatment time can result with prominent changes in the facial profile and dentition, and the outcomes can be maintained at the long-term follow-up periods.

This case report describe the management of a 22 years old male patient having class II div 2 malocclusion with traumatic deep bite. Intraoral examination revealed that patient had lingually inclined maxillary central incisor, labially flared maxillary lateral incisors, exaggerated lower curve of spee, and moderate crowding in lower jaw. Patient also tend to exhibit deep mentolabial sulcus and unaesthetic smile. Anterior flat bite plane was treatment plan for improving deep bite and also Mandibular downward backward rotation and Camouflage nonextraction treatment was decided for this patient because presence of lower crowding which is easy to correction and flare lower incisor for improving overjet and interincisal angle.Ban J Orthod & Dentofac Orthop, April 2015; Vol-5 (1-2), P.33-36

This case report describes the orthodontic treatment of an adult patient, who presented an Angle Class II division 2 malocclusion, with deep traumatic overbite, retroclined incisors with proclined left  maxillary lateral incisor and mild gingival recessions. Treatment of an adult Class II patient requires careful diagnosis and a treatment plan involving esthetic, occlusal, and functional considerations. The patient was treated with extraction of four first premolars to relieve crowding, with simultaneous correction of the deep bite by intrusion of the upper and/or lower incisors using fixed appliance mechanotherapy.Ban J Orthod & Dentofac Orthop, April 2013; Vol-3, No.2
