In Class II of the 4 Angles of Classification, what type of occlusion occurs?

In Class II of the Angle's classification of occlusion, the condition known as disto-occlusion or overbite occurs. This classification is characterized by the positioning of the maxillary (upper) teeth relative to the mandibular (lower) teeth. In this case, the first molar of the lower jaw is positioned further back compared to the first molar of the upper jaw. This positioning leads to the upper teeth overlapping the lower teeth more than what is considered normal.

Disto-occlusion often results in an overbite, where the upper front teeth significantly overlap the lower front teeth vertically. This can affect both the aesthetic appearance and functional aspects of biting and chewing. Understanding Class II occlusions is crucial for dental assistants as they work with orthodontic treatment and recommendations for patients experiencing this alignment issue.

In contrast to disto-occlusion, the other types in the classification system describe different relationships between the upper and lower teeth that do not match the characteristics of Class II occlusion.
