Understanding the 4 Types of Division Classes in Orthodontics

A class II malocclusion is a common type of misalignment, when the upper teeth protrude above the lower teeth. This type of malocclusion was first identified by Edward Angle, the father of modern orthodontics, in 1890. He developed a system for classifying bite problems based on the position of six-year-old molars. Patients can experience a variety of dental issues, from gum problems to overcrowding and tooth decay.

General and pediatric dentists who have taken an in-person or online orthodontic course can treat class I and class II malocclusions using straight wire orthodontics. Treatment will depend on the type and severity, but some options include palate expanders, braces, or surgery. If a class II malocclusion is not corrected early in life, or if the mismatch in jaw size is so large that braces alone cannot correct the problem, adults may need orthognathic (mandibular) surgery, an expensive and invasive procedure. It is not enough to classify orthodontic malocclusions based solely on the classification of the teeth. Class I malocclusion is the most common type of misalignment and is characterized by normal alignment of the teeth and jaws.

Class II malocclusion is when the upper teeth protrude over the lower teeth. Class III malocclusion is when the lower teeth protrude over the upper teeth. Finally, Class IV malocclusion is when there is a deep bite, where the lower front teeth are hidden behind the upper front teeth. It is important to understand these four types of division classes in orthodontics in order to properly diagnose and treat dental issues.

Orthodontists use these classifications to determine which treatment plan will be most effective for each patient. By understanding these four types of division classes, dentists can provide better care for their patients and help them achieve a healthy smile.
