Classification of Malocclusion - Columbia University

Class II Malocclusion Class II Malocclusion has two divisions to describe the position of the anterior teeth. Class II Division 1 is when the maxillary anterior teeth are proclined and a large overjet is present. Class II Division 2 is where the maxillary anterior teeth are retroclined and a deep overbite exists. Class II Malocclusion Division 1
