- Abstract Malocclusion has the third highest prevalence of oral health problem after caries and periodontal disease. Distribution of malocclusion in some population may vary and have high prevalence. The purpose of this study was to examine distribution of malocclusion based on Angle classification and its difference based on gender. This study was a descriptive study using 385 medical records and study models of patient in the Department of Orthodontics Faculty of Dentistry in 2009-2013. The sampling method was purposive sampling based on inclusion and exclusion criteria. The result showed that 41.55 % of sample had Angle Class I, 26.75 % Class II subdivision, 18.44 % Class II division 1, 5.71 % Class III subdivision, 4.7 % Class II division 2 and 2.85 % Class III. Distribution of some common malocclusions was 49,61 % mandibular crowding, 30.90 % anterior crossbite, 21.55 % maxillary spacing, 40.25 % of sample had normal overjet, 19.48 % excessive overjet, 69.61 % had normal overbite, 14.02 % deep bite, 9.35 % edge to edge and 7.79 % open bite. Deep bite showed the difference between boys and girls. Key words: distribution, malocclusion, Angle classification Abstrak Maloklusi merupakan masalah kesehatan mulut dengan prevalensi tertinggi ketiga setelah karies dan penyakit periodontal. Distribusi maloklusi menunjukkan hasil yang berbeda-beda dengan prevalensi cukup tinggi pada setiap populasi di dunia. Tujuan penelitian ini adalah untuk mengetahui distribusi maloklusi berdasarkan klasifikasi Angle dan melihat apakah terdapat perbedaan antara laki-laki dan perempuan. Jenis penelitian ini adalah penelitian deskriptif menggunakan 385 rekam medik dan model studi pasien di Departemen Ortodonsia RSGMP FKG USU tahun 2009-2013. Pemilihan sampel dilakukan menggunakan metode purposive sampling berdasarkan kriteria inklusi dan eksklusi. Hasil penelitian menunjukkan 41,55 % sampel memiliki hubungan molar Klas I Angle, 26,75 % Klas II subdivisi, 18,44 % Klas II divisi 1, 5,71 % Klas III subdivisi, 4,67 % Klas II divisi 2 dan 2,85 % Klas III. Bentuk maloklusi yang paling umum adalah crowding rahang bawah 49,61 %, crossbite anterior 30,90 % dan spacing rahang atas 21,55 %. Sebanyak 40,25 % sampel memiliki overjet normal, 19,48 % overjet berlebih, 69,61 % overbite normal, 14,02 % deep bite, 9,35 % edge to edge dan 7,79 % open bite. Deep bite menunjukkan adanya perbedaan distribusi berdasarkan jenis kelamin. Kata kunci: distribusi, maloklusi, klasifikasi Angle
