Background: Planning and provision of orthodontic services may require some baseline epidemiological data with regards to the distribution of malocclusion and its severity within a given population.

Aim: To analyze the distribution of malocclusion and its occlusal characteristics in Black patients referred to the Free State orthodontic clinic with regards to age, gender and Angle’s malocclusion.

Materials and Method: Study models of 391 orthodontic patients (235 female and 156 male) with the mean age of 15.4 years were analyzed to determine the distribution of malocclusion using Angle’s classification and other occlusal characteristics such as overjet, overbite, open bite, crossbite and the degree of incisor irregularity.

Result: The malocclusion status in a sample of the Free State patients seeking orthodontic treatment was recorded as 72.1% for Class I, 17.1% for Class II, and 10.8% for Class III subjects respectively. The occurrence of occlusal discrepancies was large overjet in 30.4%, deep overbite in 25.8%, anterior open bite in 9.2%, anterior crossbite in 61.4%, posterior crossbite in 27.4% and increased incisor irregularity in 75.7% of the total sample. 24.3% of the subjects required little or no treatment, 33.2% required moderate treatment, and 42.5% required great/severe treatment according to the modified DHC scores.

Conclusion: The need for orthodontic treatment in this sample is high and the prevalent occlusal characteristics are complex in nature. Treatment of these malocclusions will require qualified orthodontic specialists to carry out.
