Abstract


Maloklusi klas III true skeletal merupakan kasus yang sulit dirawat dan  mudah terjadi relaps. Perawatan ideal kasus ini memerlukan tindakan bedah, namun apabila hal tersebut tidak memungkinkan maka dilakukan perawatan kamuflase. Reverse overjet, atau gigitan terbalik, tipikal mempunyai penyimpangan posisi insisivus atas dan bawah akibat malrelasi maksila dan atau mandibula. Tujuan artikel ini adalah menyajikan perawatan ortodontik kamuflase menggunakan teknik Begg pada maloklusi ini. Pasien perempuan umur 24 tahun mengeluhkan gigi depan berjejal dan tidak nyaman untuk mengunyah makanan. Diagnosis kasus adalah maloklusi Angle klas III, hubungan skeletal klas III dengan protrusif bimaksilar, incisivus atas dan bawah retrusif, pergeseran median line rahang atas ke kanan, disertai edge to edge bite anterior, cross bite posterior dan openbite posterior. Pasien dirawat dengan  pencabutan gigi premolar kedua atas,dan premolar pertama  bawah untuk mengatasi kondisi kasus tersebut. Kesimpulan dua tahun setelah perawatan, tampak sudut interinsisal berkurang, reverse overjet terkoreksi, edge to edge bite, cross bite dan openbite terkoreksi.


Treatment of Class III malocclusion with Reverse Overjet using Orthodontic Begg Technique. A true skeletal class III malocclusion is a difficult case to be treated as it can get easily relap. The ideal treatment of this skeletal types requires a surgery, but if it is not possible, an orthodontic camouflage can be conducted. Reverse overjet typically has upper and lower incisor position deviation due to the mesial position of the mandible in relation to the maxilla.The purpose of this article is to present camouflage orthodontic treatment using Begg orthodontic technique in Class III malocclusion case with reverse overjet. A 24 year-old female patient complained about her front teeth crowding and uncomfortable mastication. From the diagnosis, there was true dento skeletal class III malocclusion with bimaxilary protrusion, bidental retrusion and edge to edge bite. The lower incisors were shifted to the right. The posterior teeth were crossbite and openbite. The patient were treated with extraction of the right upper second premolars and lower first premolars.After 2 years of treatment, it is concluded that the interinsisal angle decreases and the reverse overjet, the edge to edge bite, the crossbite and the openbite are corrected as well.
