AbstrakPendahuluan: Perawatan maloklusi kelas III sebaiknya dilakukan sedini mungkin pada saat pasien dalam masa pertumbuhan dan perkembangan, sehingga pertumbuhan dapat diarahkan. Penatalaksaan lebih awal akan memberikan hasil yang lebih baik dari profil maupun oklusinya dan dapat mencegah terjadinya kelainan yang lebih berat. Tujuan: memperbaiki gigitan silang (crossbite) yang terjadi pada gigi anterior dan posterior sehingga terbentuk relasi gigi rahang atas dan rahang bawah yang normal, dengan overjet dan overbite normal, koreksi gigi yang berjejal dan memperbaiki garis median sehingga diperoleh estetik penampilan yang lebih baik. Penatalaksanaan Kasus: Menggunakan alat cekat dengan sistem straight wire, tahap pertama perawatan dilakukan levelling dan unravelling untuk koreksi crowding gigi anterior. Pasien masih berusia 14 tahun sehingga pemakaian elastik intermaksiler klas III sangat efektif untuk menghambat pertumbuhan rahang bawah dan memacu pertumbuhan rahang atas sehingga terbentuk overjet positif. Kesimpulan: Untuk kasus kelas III yang dilakukan lebih dini dapat dilakukan perawatan ortodontik tanpa dilakukan pembedahan. Hasil perawatan relatif memuaskan dengan terkoreksinya crowding dan crossbite di anterior maupun posterior. Profil pasien menjadi lebih baik, semula cekung terkoreksi menjadi lurus.
