What dental classification is associated with a patient who has flared anterior incisors?

The classification associated with a patient who has flared anterior incisors is Class 2 Division 1. This classification typically indicates a significant overjet and protruded maxillary incisors, which often presents clinically as flared teeth. In Class 2 Division 1 malocclusion, the first molars are positioned more towards the back of the mouth compared to the opposing molars, while the upper front teeth tend to be positioned forward and can be labioverted, contributing to the flaring appearance.

The characteristics of Class 2 Division 1 are distinguished from Class 2 Division 2, where the incisors might be retroclined rather than protruded and flared. Class 1 refers to a normal occlusion with all teeth in proper alignment, while Class 3 indicates a more severe underbite with the lower jaw positioned further forward than the upper jaw, which does not correlate with the presentation of flared incisors. Therefore, the description of flared anterior incisors aligns perfectly with the features of Class 2 Division 1 malocclusion.
