Pada perawatan ortodontik menggunakan teknik Begg koreksi overjet besar dan palatal bite dapat dilakukan secara bersamaan karena memakai differential force. Tujuan artikel ini adalah untuk menyajikan hasil koreksi overjet besar dan palatal bite pada kasus maloklusi klas II divisi 1 menggunakan alat ortodontik cekat teknik Begg. Kasus: Pasien laki-laki usia 17 tahun, dengan keluhan gigi rahang atas berjejal dan maju. Diagnosis: maloklusi Angle Klas II divisi 1 dengan hubungan skeletal klas II, mandibular retrusif dan bidental protrusif disertai crowding sedang, overjet sebesar 10,78 mm, palatal bite dan pergeseran garis median rahang atas ke kiri 1,5 mm. Perawatan menggunakan alat cekat teknik Begg diawali pencabutan kedua gigi premolar pertama atas dan kedua premolar kedua rahang bawah. Tahap pertama perawatan menggunakan multiloop arch wire 0,014”, anchorage bend 45º dan elastik intermaksiler klas II. Setelah 7 bulan perawatan, hasil menunjukkan crowding terkoreksi, overjet besar dan palatal bite terkoreksi sempurna. Overjet menjadi 2,2 mm dan overbite menjadi 2 mm.
