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.

Patients with a skeletal class II malocclusion are usually associated with a prognathic maxilla with orthognathic mandible or a retrognathic mandible with orthognathic maxilla or a combination of both. Patients with severe prognathic maxilla are usually associated with increased overjet which results in a lower lip trap. The lip trap should be managed the earliest as it will lead to further proclination of the upper anterior teeth and also hinder the normal growth of the mandible. To overcome the limitations of a conventional lip bumper, we arrived at an idea of fixed lip bumper supported using mini-implants.

Abstract This paper describes the treatment of a female patient, aged 23 years and 5 months, with a Class II division 1 malocclusion, who showed severe anterior protrusion and lower anterior crowding. Specially-designed orthodontic mini-implants were placed bilaterally in the interdental space between both the upper and the lower posterior teeth. Both lower first molars showed severe apical lesions. Therefore, the treatment plan consisted of extraction of both upper first premolars and lower first molars, en masse retraction of the upper six anterior teeth, lower anterior alignment, and protraction of all the lower molars. C-implants® were used as substitutes for maxillary posterior anchorage teeth during anterior retraction and as hooks for mandibular molar protraction. The correct overbite and overjet were obtained by intruding and retracting the upper six anterior teeth into their proper positions. The dentition was detailed using conventional orthodontic appliances. The upper C-implants contributed to an improvement in facial balance, and the lower C-implants made it possible to protract the lower second and third molars with less effect on the axis of the lower anterior teeth. The active treatment period was 29 months and the patient's teeth continued to be stable 11 months after debonding.

Abstract Objective: To examine the skeletal, dental, and soft tissue treatment effects of retraction of maxillary anterior teeth with mini-implant anchorage in nongrowing Class II division 1 female patients. Materials and Methods: Twenty-three patients (overjet ≥7 mm) were selected on the basis of predefined selection criteria. Treatment mechanics consisted of retraction of anterior teeth by placing mini-implants in the interdental bone between the roots of the maxillary first molar and second premolar. A force of 150 g was applied, bilaterally. Treatment effects were analyzed by taking lateral cephalograms and study casts at T1 (before initiation of retraction) and at T2 (after complete space closure). Results: The upper anterior teeth showed significant retraction (5.18 ± 2.74 mm) and intrusion (1.32 ± 1.08 mm). The upper first molar also showed some distal movement and intrusion, but this was not significant (P > .05). The upper and lower lips were retracted by 2.41 mm and 2.73 mm, respectively, and the convexity angle reduced by over 2° (P < .001). Conclusion: Mini-implants provided absolute anchorage to bring about significant dental and soft tissue changes in moderate to severe Class II division 1 patients and can be considered as possible alternatives to orthognathic surgery in select cases.

Impaksi gigi terjadi karena gigi gagal untuk erupsi secara sempurna pada posisinya akibat terhalang oleh gigi lain maupun jaringan lunak atau padat di sekitarnya. Gigi yang sering mengalami impaksi adalah gigi geraham ketiga rahang bawah, gigi kaninus rahang atas, dan gigi premolar kedua. Impaksi premolar sering terjadi karena pencabutan prematur dari gig geraham desidui. Gigi premolar pertama jarang terjadi impaksi dibandingkan premolar kedua. Tujuan laporan kasus adalah untuk memaparkan penatalaksanaan perawatan untuk mengkoreksi impaksi gigi premolar pertama mandibula menggunakan alat cekat teknik Begg tanpa prosedur bedah. Pria 21 tahun mengeluhkan gigi yang berjejal pada rahang atas dan rahang bawah. Gigi kaninus desidui kiri rahang atas dan rahang bawah belum tanggal. Diagnosis pasien adalah Maloklusi Angle Klas II  divisi 2 bimaksiler protrusif dengan hubungan skeletal klas II, gigi anterior maksila retrusif, disertai impaksi gigi premolar pertama mandibula kiri. Perawatan dilakukan dengan menggunakan alat cekat teknik Begg dan pencabutan gigi desidui, Kesimpulan, impaksi gigi premolar pertama mandibula dapat tercapai pada tahap pertama teknik Begg tanpa pendekatan tindakan bedah, tahap selanjutnya yang akan dicapai adalah tahap memperbaiki inklinasi aksial gigi.Treatment Of Class II Division 2 Angle Malocclusion With Mandibular Premolar Tooth Impaction Using Begg Technique. Tooth impaction is a tooth that fails to erupt perfectly to its position because of the other tooth, surrounding soft or hard tissue that blocks its eruption. Premolar often fails to erupt due to a premature extraction of deciduous molar. This case study aims to illustrate the treatment of mandibular first premolar impaction using Begg technique for fixed appliance. The experiment was conducted to a 21 year-old male patient who complained about his crowding of upper and lower teeth, also the persistence of his upper and lower left deciduous canine. The case was diagnosed as class II division 2 angle malocclusion with bimaxillary protrusion with class II skeletal relation, and maxillary anterior teeth retrusion. The left mandibular of first premolar teeth was impacted. The treatment using Begg technique has helped to fix the appliance with the extraction of the deciduous teeth. From the evaluation, it can be concluded that the treatment of impacted mandibular first premolar is achieved on the first stage of Begg technique without surgical approach. The next objective of the treatment is to correct the teeth axis.

The dentoskeletal characteristics of Class II malocclusion subjects were evaluated using cephalometric radiograph and dental cast of 60 untreated patients. The sample included 30 Class II Division 1 and 30 Class II Division 2 malocclusion patients. The inter-canine, inter-premolar, inter-molar, inter-canine alveolar, inter-premolar alveolar, inter-molar alveolar widths are measured on study models. The result showed statistically significant difference between the groups for mandibular inter-canine width only. The cephalometric analysis revealed that SNB angle was responsible for the skeletal sagittal difference between the two groups except for the position of maxillary incisors. No basic difference in dentoskeletal morphology existed between Class II Division 1 and Class II Division 2 malocclusions.

This paper describes the orthodontic treatment of two cases that were successful in winning the British Orthodontic Society (BOS) Membership in Orthodontics (MOrth) Cases Prize in 2019. The first case describes the management of a 12-year-old girl with a Class II division 2 malocclusion complicated by moderate upper and lower arch crowding, multiple unerupted teeth, restored lower first permanent molars, pseudo-transposition of the lower left lateral incisor and canine, and diminutive upper lateral incisors. Treatment involved a combination of an upper removable appliance followed by upper and lower preadjusted edgewise fixed appliances. Anteroposterior correction and overbite reduction was achieved with triangular Class II elastics with posterior occlusal disengagement. Both upper permanent canines were exposed and aligned, and the diminutive upper incisors built up with resin-based composite. Treatment was completed over a period of 23 months. The second case describes the management of a 13-year-old boy with a Class II division 2 malocclusion complicated by severe upper and lower arch crowding with unerupted UR5, UL4, LR3, rotated LR5, an increased overbite complete to tooth, buccally displaced upper canines and hypoplastic upper first premolars. Treatment involved a first phase of functional appliance therapy, followed by the extraction of UR4, UL4, LL5, LR4 and upper and lower preadjusted edgewise fixed appliances over a 28-month period.
