Open anterior occlusal relationship

This code describes an open bite where the anterior teeth (incisors and canines) do not overlap vertically when the posterior teeth are in occlusion. Specifically, it refers to a malocclusion where there is a vertical gap between the upper and lower front teeth. This condition can affect speech, mastication, and facial aesthetics.

Use this code for patients diagnosed with an anterior open bite where the lack of vertical overlap is evident in the occlusal relationship. Documentation should clearly state "anterior open bite" or "open anterior occlusal relationship" and specify the anterior region. This code is appropriate when the open bite is a primary diagnosis or a significant contributing factor to other dental issues.

• Differentiate from posterior open bites, which involve the back teeth and have different codes.
• Ensure documentation specifies "anterior" to support this code; a general "open bite" may require further clarification.
• Consider sequencing with codes for underlying causes (e.g., thumb sucking, tongue thrust) or related conditions (e.g., speech impediments) if applicable.
