The ideal proportion of face in various area must be known for a data source in establishing a diagnosis and making the right treatment plan so that the orthodontic treatment achieves the best results. This study aimed to measure facial index based on Angle’s classification of malocclusion on Deuteromalay Subrace. Method: This research was a descriptive study with cross sectional approached. The research population were undergraduate students of Faculty of Dentistry, Padjadjaran University, Deuteromalay Subrace.

The facial index value data based on Angle’s classification of malocclusion in this study for men was 6 malocclusion subclasses with 4 different facial types, for women was 6 malocclusion subclasses with 5 different facial types. The most Angle’s classification of malocclusion in men and women were class I type 1 and the most facial types were mesoprosopic in men and euryprosopic in women.
