ABSTRACT A healthy 15-year-old boy with anterior open bite, edge-to-edge transverse discrepancy, and Class III skeletal relationship sought a nonsurgical orthodontic treatment. The patient was treated with premolars extraction, a Hyrax expander and intrusion mechanics with vertical elastics. This mechanics allowed for excellent facial and occlusal results. The final occlusion presented Class I molar and canine relationships, ideal overjet and overbite, and straight facial profile. Analysis of the posttreatment and follow-up radiographs showed that the treatment outcomes remained stable seven years after active orthodontic treatment. Thus, although combined orthodontic and surgical treatment should be considered for patients with this skeletal malocclusion, this case report proves that well controlled orthodontic movement with the patient’s cooperation can be a valid alternative treatment, with good and stable outcomes for patients who refuse surgery.

ABSTRACT The present case report describes the orthodontic treatment of a young adult patient (18y / 1m), Class III skeletal malocclusion, with mandibular prognathism and significant dental compensation. The canine relation was Class III, incisors with tendency to crossbite and open bite, moderate inferior crowding, and concave profile. Skeletal correction of malocclusion, facial profile harmony with satisfactory labial relationship, correction of tooth compensation and normal occlusal relationship were obtained with orthodontic treatment associated to orthognathic surgery. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO), as part of the requirements to become a BBO diplomate.

ABSTRACT A 29-year-old female patient with unilateral condylar hyperplasia (UCH) of the left side presented with facial asymmetry, maxillary transverse occlusal plane (MXTOP) cant, posterior open bite, and Class III relationship. Treatment consisted of proportional condylectomy of the left condyle for management of UCH, and fixed orthodontic treatment with intrusion of the left maxillary molars to correct the MXTOP cant and remaining chin point deviation (CPD). Proportional condylectomy with a 14-mm resection of the left condylar head improved the CPD from 11.5 mm to 7.8 mm and resolved the posterior open bite on the left side. However, it produced a Class II relationship on the right and left sides, posterior open bite on the right side, and anterior open bite. Fixed orthodontic treatment with 1.8-mm intrusion of the left maxillary molars using miniscrews corrected the MXTOP cant from 3.5 mm to 1.7 mm, reduced the remaining CPD from 7.8 mm to 3.7 mm, produced counterclockwise rotation of the mandible, and resolved the posterior open bite on the right side and the anterior open bite. After 16 months of total treatment, normal overbite/overjet and Class I relationship were obtained. Treatment results were well maintained after 5 years of retention. For the correction of UCH, it is important to determine the amount of condylar head resection and accurately simulate the correction of CPD and MXTOP cant through intrusion of the maxillary molars.

Setting: College of Dental Surgery, B P Koirala Institute of Health Sciences, Sunsari, Nepal. Aims: To evaluate the pattern and distribution of malocclusions in patients seeking for orthodontic treatment from Sunsari district of Nepal. Material and Methods: Total of 350 patients who were permanent inhabitants of Sunsari district of age range 8-36 years were included in the study. A standard format was prepared to record the data. Descriptive statistics for mean, standard deviation and frequencies were calculated. Ages and Class I, II and III malocclusions were cross tabulated to check for any relationship using ANOVA. Intra investigator error was calculated using kappa statistics. Results: The prevalence of Class I, II and III malocclusions were 62.28 %, 29.4%.and 8.2% respectively. Out of 350 cases studied for various occlusal traits the nature of distribution of various occlusal findings were: absent teeth-12.6%, supernumerary teeth-2.9% ectopic eruption-7.1%, midline diastema-16%, incisor crowding-52.9%, spacing-30%, malformations-3.1%, increased overjet (>4mm)- 42.3%, anterior open bite . 5.1% and deep bite (>4mm )- 40 % and cleft lip and palate was 0.28%. Most prevalent age group seeking orthodontic treatment was 12-24 years with females to male ratio of 2.3:1 Comparison of mean ages with different malocclusion groups using ANOVA was statistically not significant. Conclusion: Class I malocclusion was the most prevalent followed by Class II malocclusion and the Class III malocclusion showed least prevalence. There were diverse occlusal traits.

ABSTRACT Introduction: Tooth agenesis is one of the most common dental anomalies; however, the concomitant occurrence of opposite dental numerical variation of hypohyperdontia is extremely rare. Objective: To report the successful orthodontic management of a patient with non-syndromic concomitant bilateral agenesis of mandibular canines and two midline inverted supernumerary maxillary teeth. Case report: 21-year-old female patient with a chief complaint of protrusive right maxillary central incisor. The patient was diagnosed with a mild Class II skeletal base, Angle Class III molar relationship and increased overjet associated with hypohyperdontia. Anterior open bite accompanied with tongue-thrusting habit were also observed. Two temporary anchorage devices (TADs) were implanted at the buccal side of the maxillary molar region to control vertical height. Anterior teeth retraction was done after extraction of the maxillary first premolars, to improve the excessive overjet. The treatment mechanics involved lingual brackets system for the maxillary arch and transpalatal arch for anchorage control. Results: The total active treatment period was 35 months. Acceptable occlusion with increased bite force and contact area as well as functional excursion were established without interference, following complex orthodontic treatment with premolar substitution. The resultant occlusion and a satisfactory facial profile were maintained after 29 months of retention. Conclusion: The present case report provides implications regarding the orthodontic treatment of hypohyperdontia-associated substitution for missing teeth as an effective option for improving aesthetic and functional aspects.

Objective Orthodontic camouflage treatments improve occlusion but might worsen facial profile in patients with Class III malocclusion. It has been reported that surgical clockwise rotation of maxillomandibular complex (MMc) improves facial profile by reducing chin prominence and chin throat length in patients with Class III malocclusion. The purpose of this report was to illustrate two orthodontic techniques for clockwise rotation of the MMc in late teenagers with Class III malocclusion and preliminarily evaluate their clinical effects. Patients and Methods Six patients in late teenage with Class III malocclusion were included in this preliminary report. Bite raisers were first placed on the upper molars to open the bite and clockwise rotate the mandible. Intermaxillary elastics were then applied vertically between the upper and lower dentitions in 3 patients for bimaxillary extrusion (Technique-1) or between the upper dentition and the lower temporary anchorage devices (TADs) in another 3 patients (Technique-2) for upper dentition extrusion and closure of the anterior open bite. The three-dimensional cone-beam computed tomography images taken before and after orthodontic treatment were superimposed to evaluate the treatment effects of MMc clockwise rotation for both techniques. Results The Technique-1 extruded the upper and lower dentitions, rotated the mandible clockwise 2.01°, moved chin down 2.98 mm, and back −1.64 mm, although the mandible grew 2.47 mm during the treatment period. The Technique-2 extruded the upper dentition, rotated the mandible clockwise 0.90°, moved chin down 1.78 mm, but slightly forward 0.47 mm due to the mandible grew 2.50 mm and lower dentition was not extruded. Conclusions The orthodontic clockwise rotation of MMc is an effective technique for orthognathic camouflage. The applications of bite raisers and bimaxillary dentition extrusion could be more effective than single dentition extrusion with TADs in the mandible for clockwise rotation of MMc and improvement of occlusion and facial profile in late teenagers with Class III malocclusion. However, the comprehensive clinical effects and long-term stability need further clinical studies.

Pendahuluan: Perawatan ortodonti kamuflase adalah perawatan untuk menyamarkan diskrepansi skeletal dengan mengubah posisi dan angulasi gigi-gigi pada lengkung rahang. Perawatan tersebut merupakan perawatan yang dapat dipilih selain bedah ortognatik bagi kasus maloklusi skeletal kelas III pada pasien dewasa. Maloklusi skeletal kelas III sering pula disertai dengan keadaan lain seperti gigitan terbuka anterior yang menambah kompleksitas modalitas perawatan. Tujuan laporan kasus ini untuk menjelaskan pilihan modalitas perawatan pasien maloklusi skeletal kelas III secara kamuflase ortodonti. Laporan kasus: Pasien wanita usia 19 tahun 2 bulan datang ke klinik Ortodonti RSGM FKG UI dengan keluhan gigi atas depan tidak teratur dan gigi depan atas dan bawah tidak bertemu. Diagnosis menunjukkan pola skeletal kelas III dengan posisi maksila dan mandibula terhadap basis cranii retrognati (SNA 73°, SNB 74°, ANB -1°)  disertai dengan crowding sedang dan gigitan terbuka anterior. Tipe wajah pasien dolikofasial, simetris dan seimbang. Profil jaringan lunak dan skeletal cekung. Kasus ini dirawat dengan pendekatan ortodonti kamuflase tanpa pencabutan menggunakan piranti cekat standar Edgewise untuk mengoreksi crowding pada lengkung gigi atas dan bawah serta gigitan terbuka pada regio anterior. Perawatan ortodonti selesai dalam waktu 13 bulan dan crowding pada lengkung gigi atas dan bawah serta gigitan terbuka pada regio anterior telah terkoreksi. Simpulan: Perawatan ortodonti kamuflase pada maloklusi kelas III skeletal dengan gigitan terbuka anterior ringan merupakan pilihan perawatan yang cukup baik karena dapat mengoreksi maloklusi dengan kompensasi dentoalveolar sehingga diperoleh oklusi yang baik dan stabil. Hasil perawatan menunjukan hasil yang cukup baik dan dapat diterima oleh pasien.Kata kunci: Maloklusi skeletal kelas III, crowding, open-bite anterior, standar edgewise, ortodonti kamuflase. ABSTRACTIntroduction: Orthodontic camouflage is a treatment to disguise skeletal discrepancies by changing the teeth position and angulation in the jaw arch. This treatment is an option other than orthognathic surgery for skeletal class III malocclusion in adult patients. Skeletal class III malocclusion is often accompanied by other conditions such as an anterior open-bite which adds the complexity of the treatment modality. This case report was aimed to describe the choice of treatment modality for skeletal class III malocclusion patients by orthodontic camouflage. Case report: A female patient aged 19 years and two months came to the Orthodontic Clinics at the Faculty of Dentistry of University of Indonesia Dental Hospital (RSGM FKG UI) with complaints of irregular maxillary anterior teeth, and the maxillary and mandibular anterior teeth did not overlap. The diagnosis showed a skeletal class III pattern with the maxillary and mandibular position against the retrognathic cranii base (SNA 73°, SNB 74°, ANB -1°) accompanied by moderate crowding and anterior open-bite. The patient’s face type is dolichofacial, symmetrical and balanced, with the concave soft and skeletal tissue profiles. This case was treated with a non-extraction camouflage orthodontic approach using the standard edgewise fixed appliance to correct crowding in the maxillary and mandibular dental arches and open-bite in the anterior region. The orthodontic treatment was completed within 13 months, and crowding in the maxillary and mandibular dental arches and open-bite in the anterior region were corrected. Conclusion: Camouflage orthodontic treatment is a good treatment option for skeletal class III malocclusion with a mild anterior open-bite because it can correct malocclusion with dentoalveolar compensation to obtain a good and stable occlusion. The treatment results show good results and can be accepted well by the patient.Keywords: Skeletal class III malocclusion, crowding, anterior open-bite, standard edgewise, orthodontic camouflage.
