Malocclusions - Angle Classifications

Class I Malocclusion

A Class I malocclusion has the proper molar relationship. But the teeth still have problems, such as crowding together or they are spaced apart and/or have an overbite, an open bite, a posterior crossbite, an anterior crossbite, etc.

Class II Malocclusion

In a Class II malocclusion, the upper molar is too far forward. The upper front teeth often protrude or the lower teeth or jaw are positioned back relative to the upper teeth or jaw. This malocclusion often results in an overbite, or "buck teeth." This is the most common malocclusion see in Dr. Fulton's office.

Class III Malocclusion

In a Class III malocclusion, the upper molar is too far back. The lower front teeth often protrude or the lower teeth or jaw are positioned ahead relative to the upper teeth or jaw. This malocclusion is also called an underbite, or "bulldog bite." This is the least common malocclusion in America.
