angle classifications

Angle classifications refer to how the upper and lower teeth align when the jaws are closed. The most common classifications are Class I, Class II, and Class III. Class I is normal, with the upper teeth slightly over the lower. Class II, often called an overbite, happens when the upper teeth and jaw significantly project forward. Class III, known as an underbite, occurs when the lower jaw and teeth extend beyond the upper. These classifications help dentists determine orthodontic treatment needs and plan appropriate interventions for proper bite function and facial balance.
