The prevalence of malocclusion differs significantly from race to race. The cause of malocclusion could be multifactorial. Previous studies have demonstrated quantitative information on skeletal and dental relations in different countries. This study focuses on patients who had received orthodontic data collection and analysis in a specific medical center. Skeletal relation and Angle’s dental classification of male and female were statisticized and analyzed. Skeletal relation of Class I was 45.4%, Class II was 29.5%, and Class III was 25.1%. Angle’s dental classification of Class I was 39.3%; Class II was 30.8%; Class III was 29.9%. There was a statistically significant difference between the distribution of malocclusion and sex. Compared to previous studies, a similar distribution of skeletal relation is shown in oriental studies. The annual distribution trend is also investigated to provide brief information on patients attending the medical center for orthodontic inspection. Our study provides brief information on skeletal relation and Angle’s dental classification, which can help set clinical training programs for residents and postgraduates. Moreover, epidemiological studies with a larger sample and further analysis are still required to obtain a more practical situation of malocclusion in the Taiwanese population.
