ABSTRACT Obtaining long term stability allied to functional and aesthetic balance is the main goal of any orthodontic-orthopedic therapy. This case report describes the orthodontic therapy applied to a 7-year-9-month old child, who presented a Class II, division 1 malocclusion associated to skeletal open bite. Functional and skeletal corrections (sagittally and vertically) were obtained by means of mandible advancement achieved with a closed Balter’s bionator appliance followed by a fixed appliance. This approach showed to be efficient in accomplishing both functional and aesthetic goals, that were kept stable five years after the treatment was finished. This case report was presented to the Board of Directors of the Brazilian Board of Orthodontics and Facial Orthopedics (BBO), as partial requirement to becoming a Diplomate of the BBO.

Maloklusi klas II divisi 1 dentoskeletal disertai dengan retrusi mandibula dan lengkung rahang yang sempit dapat terjadi akibat dari faktor keturunan dan diperparah oleh kebiasaan buruk. Kondisi maloklusi tersebut ditandai dengan adanya palatal bite dan overjet yang besar. Perawatan maloklusi klas II divisi 1 pada masa pertumbuhan dan perkembangan dapat dilakukan dengan menggunakan alat ortodontik fungsional, salah satunya adalah Bionator. Pemilihan bionator bertujuan untuk menuntun rahang bawah untuk bergerak ke posisi yang diinginkan dan memperlebar lengkung rahang. Tujuan dari penulisan laporan kasus ini adalah menyajikan hasil kemajuan perawatan maloklusi klas II divisi 1 dengan menggunakan alat ortodontik fungsional Bionator. Pasien perempuan berumur 12 tahun mengeluhkan gigi depan atas maju sehingga mengganggu penampilan. Diagnosa kasus adalah maloklusi klas II divisi 1 dentoskeletal disertai dengan retrusi mandibula, bidental protrusif, palatal bite, kontraksi lengkung rahang dan malposisi gigi individual. Pasien dirawat dengan menggunakan alat ortodontik fungsional Bionator. Perawatan setelah tiga bulan, secara klinis terlihat profil pasien terkoreksi, overjet berkurang, palatal bite hilang, dan open bite posterior. Treatment of dentoskeletal class II division I with mandibula retrussion using Bionator appliance. Malocclusion Class II division 1 dentosceletal followed with mandibular retrusion and contraction of arch could be happened by genetic and bad habit. It was showed with severe palatal bite and overjet. In the development and growth phase, the treatment for that condition is fuctional appliance, such as Bionator. Bionator arranged lower jaw to the good position and distraction the arch. The purpose of this case report is to present the treatment of malocclusion dentosceletal Class II division 1 with fuctional appliance Bionator. A 12 years old female patient complained of front upper teeth are protrusive. Diagnosis is malocclusion Class II division 1 dentosceletal followed with mandibular retrusion, bidental protrusive, palatal bite, contraction of jaw and malposition individual teeth. The patient treated with fuctional appliance Bionator. After 3 months treatment, patient`s profile corrected, decreased overjet, no palatal bite, and open bite posterior.

ABSTRACTObjectives: The objective of this study was to describe the prevalence of malocclusion in a population of Central Anatolian adolescents in relation to gender.Methods: The sample comprised 2329 teenagers (1125 boys and 1204 girls), aged between 12 and 17 years (mean age: 14.6 yrs). Occlusal anteroposterior relationships were assessed using the Angle classification. Other variables examined were overjet, overbite, crowding, midline diastema, posterior crossbite, and scissors bite.Results:The results showed that about 10.1% of the subjects had normal occlusions, 34.9% of the subjects had Class I malocclusions, 40.0% had Class II Division 1 malocclusions, 4.7% had Class II Division 2 malocclusions and 10.3% had Class III malocclusions. Over 53.5% had normal overbites, and 18.3%, 14.4%, 5.6%, and 8.2% had increased, reduced, edge-to-edge or anterior open bite values, respectively. Overjet relationship was normal in 58.9%, increased in 25.1%, reversed in 10.4%, and edge-to-edge in 5.6%. A posterior crossbite registered in 9.5% and scissors bite in 0.3%. Anterior crowding was present in 65.2% of the sample and midline diastema in 7.0%. No clear gender differences were noted, except for normal overbite (most frequent in girls, P>.001) and increased overbite (most frequent in boys, P>.05)Conclusions: Class II Division 1 malocclusion is the most prevalent occlusal pattern among the Central Anatolian adolescents and the high values (25.1% and 18.3%) of increased overjet and overbite were a reflection of the high prevalence of Class II malocclusion.
