Abstract
Edward Angle had differentiated between the first and second divisions of his Class II type of malocclusion as early as the beginning of the 20th century. The prevalence of Class II/2 is ranging between 10-18%, making it type of malocclusion occurs the least often. This unique malocclusion, observed by Angle to have more nearly normal maxillary arch widths when compared to Class II/1 which characteristically by narrowed maxillary arches. He also described retrolication of the maxillary incisors, deep impinging vertical overbites and relatively normal nasal and lip functions. Not only that scanty patients presented with this type of malocclusion, it also has slightly different aetiologies from Class II/1. Hence, the assessment, management, and treatment of these patients can be challenging. The unique features and its aetiologies will be discussed and the different approaches of treatment as well as its challenges will be presented.
