Abstract
Maloklusi Angle klas II divisi 1 mempunyai ciri tonjol mesiobukal molar pertama atas beroklusi dengan interdental premolar kedua dan molar pertama bawah, jarak gigit yang besar, lengkung gigi sempit dan profil cembung. Bionator pertama kali diperkenalkan oleh Balter dan merupakan alat ortodontik myofungsional yang digunakan untuk merawat diskrepansi rahang. Tujuan pemaparan kasus adalah menyajikan kemajuan kasus maloklusi Angle Klas II divisi 1 disertai diskrepansi rahang menggunakan alat myofunctional bionator. Seorang perempuan berusia 13 tahun mengeluhkan gigi depan atas maju. Diagnosis pasien maloklusi Angle klas II divisi 1, hubungan skeletal klas II dengan protrusif maksila dan retrusif mandibula, protrusif insisivus atas disertai palatal bite, cross bite posterior, jarak gigit 11 mm, tumpang gigit 5,25 mm, SNA 84°, SNB 76°. Pasien dirawat menggunakan alat myofungsional bionator. Hasil perawatan setelah satu tahun overjet menjadi 6,25 mm dan SNB 78°. Kesimpulannya adalah alat myofungsional bionator efektif untuk merawat maloklusi Angle Klas II divisi 1 yang disertai diskrepansi rahang.
Class II division 1 Angle Malocclussion Treatment Using Myofunctional Bionator. Malocclusion Angle Class II division I is characterized by the upper mesio-buccal cups first permanent molars occludes in interdental second bicuspid and lower first molar permanent, increased overjet, narrow arch form, and convex profile. Bionator originally developed by Balter and used to treat jaw discrepancy. The goal of this case is to present the progress of myofunctional bionator appliance in treating malocclusion Class II division 1 with jaw discrepancies. A Female 13 years old complained protrusive anterior teeth. Diagnosis is malocclusion Angle Class II division I, class II skeletal relationship with maxilla protrusive, mandible retrusive, protrusive upper incisor, palatal bite, posterior cross bite, overjet 11 mm, overbite 5,25 mm SNA 84°, SNB 76°. Myofunctional bionator appliance used to treat the patient. Result after one year treatment, overjet reduce to 6,25 mm dan SNB 78°.
