What is a class 1 malocclusion?

Dental malocclusions are common problems that are treated by maxillofacial surgeons. There are three types of dental malocclusions: class 1, class 2 and class 3.

In this article, find out more about class 1 malocclusions, their symptoms and how to treat them.

Definition of a class 1 malocclusion

Class 1 dental malocclusion is the most common type of malocclusion. Approximately 50% to 55% of children between the ages of 6 and 17 have some form of Class 1 malocclusion.

Dental malocclusions are classified based on the positioning of the upper and lower molars. A class 1 malocclusion means that the molar position, or bite, is normal, but there are other teeth that are misaligned in some way. These anomalies can include:

• Overlapping or overcrowded teeth
• Rotated teeth
• Gaps between the teeth
• Asymmetry
• Open bite

Types of class 1 malocclusion

Class 1 malocclusions can be further categorized according to the Dewey-Anderson classification. This classification method provides more specifications on the various problems associated with class 1 malocclusions.

• Class I Type 1: overlapping anterior teeth and upper or lower incisor and canine crowding
• Class I Type 2: vertical problem, protruding maxillary incisors with spaces between the teeth
• Class I Type 3: anterior cross-bite
• Class I Type 4: posterior cross-bite
• Class I Type 5: A lack of space for teeth posterior to the canines, premolars or 2nd and 3rd molars

How to treat class 1 malocclusions

To avoid the potential consequences of a class 1 malocclusion, it is important to seek treatment promptly and have the problem corrected.

Most class 1 malocclusions can be corrected with traditional orthodontic treatments such as metal or clear ceramic braces. Sometimes, a premolar tooth extraction may be required.
