What Types (or Classes) of Malocclusion One Can Have?
Edward Angel, in 1899, classified teeth malocclusions into three categories. The first one, called Class I Malocclusion, is the most common. Here the first molars are normal, while other teeth have problems like spacing, crowding, over or under eruption. The Class II Malocclusion is a situation when the upper molars severely overlap the bottom teeth. The same can happen with jaws. The Class III Malocclusion describes the opposite situation, when the lower front teeth are more prominent then the upper front ones.
