Abstract


Maloklusi Klas III merupakan kasus ortodontik yang sulit untuk dirawat. Maloklusi ini mempunyai karakteristik profil wajah pasien cekung, prognasi mandibula, retrognasi maksila maupun kombinasi keduanya dan cross bite gigi anterior. Perawatan ortodontik interseptif pada kasus ini sangat dianjurkan untuk mencegah maloklusi berkembang lebih lanjut, memacu dan mengarahkan petumbuhan yang benar, serta mencegah tindakan pembedahan dikemudian hari. Bionator adalah alat ortodontik lepasan untuk merawat maloklusi kelas III dan penyederhanaan dari aktivator. Bionator dikombinasikan dengan chin cap untuk meningkatkan keberhasilan perawatan. Tujuan studi kasus ini adalah menganalisis efektifitas perawatan ortodontik interseptif pada maloklusi kelas III dengan penggunaan kombinasi alat ortodontik lepasan bionator dan chin cap. Pasien perempuan berusia 10 tahun, mengeluhkan dagunya panjang serta gigi depan rahang bawah maju. Pemeriksaan objektik: over jet -1 mm, overbite 1 mm, cross bite gigi 11 21 22 dengan 32 31 41 dan prognasi mandibula. Maloklusi Angle Klas III dentoskeletal, tipe skeletal kelas III, overjet: -1 mm, overbite: 1 mm, disertai prognasi mandibula, bidental protrusif, crossbite anterior: 11, 21, 22 terhadap 32 31, 41 dan malpoisisi gigi individual. Setelah 12 bulan pemakaian alat, edge to edge bite 11, 21, terhadap 32, 31, 41, terkoreksi, tetapi crossbite 22 terhadap 32 belum terkoreksi. Pemakaian bionator dilanjutkan dan dikombinasikan dengan chin cap. Perawatan masih berlangsung hingga saat ini (12 bulan). Penggunaan kombinasi alat ortodontik lepasan bionator kelas III dan chin cap sangat efektif digunakan dalam perawatan ortodontik interseptif pada pasien maloklusi kelas III.

ABSTRACT: Class III malocclusion an orthodontic cases are difficult to treat. This malocclusion has characteristics: concave facial profile, prognathism mandible, maxilla retrognati or a combination of both and anterior cross bite.

Bionator is a removable appliance, a simplification of the activator to treat Class III malocclusions. Combination bionator with the chin cup to improve the success of treatment. Objectives analyze the effectiveness of orthodontic interseptif treatment on Class III malocclusion using a combination of a removable orthodontic appliance bionator class III and chin cap. A female patient, aged 10 years old, complained about the long chin and the front teeth of the lower jaw forward. Objective examination: over jet -1 mm, overbite 1 mm, crossbite 11 21 22 with 32 31 41 and prognatism mandible. Diagnosis: dentoskeletal Angle Class III malocclusion, skeletal Class III, overjet: -1 mm, overbite: 1 mm, accompanied prognatism mandible, bidental protrusive, crossbite anterior: 11, 21, 22 to 32 31, 41 and malposition individual teeth. After 12 months, edge to edge bite 11, 21 to 32, 31, 41 corrected, but the cross bite 22 to 32 have not been corrected. Usage continued bionator combined with the chin cup.
