What is the most common type of malocclusion identified in dental examinations?

The most common type of malocclusion identified in dental examinations is Class II, Division I malocclusion. This classification is characterized by the first molars being positioned such that the lower molars sit behind the upper molars, with the upper teeth typically protruded and the lower teeth being retruded. This pattern is frequently observed in the general population, making it the most prevalent type of malocclusion.

Class II malocclusions, especially Division I, can present with aesthetic concerns such as an excessive overjet and prominence of the upper incisors. Dental practitioners often encounter this type during routine clinical assessments and orthodontic evaluations, contributing to its classification as the most common malocclusion.

Other types, like Class I and Class III, also occur but are less prevalent overall. Class I malocclusion refers to a normal relationship of the molars but may have other issues related to alignment, while Class III involves the lower molars being positioned more forward than the upper molars, which is less common in the population. Class II, Division II features a similar molar relationship but with distinct characteristics affecting the positioning of incisors, leading to its lower occurrence compared to Division I.
