What characterizes Class I malocclusion?

Class I malocclusion is characterized by a normal molar relationship, which means that the upper first molar fits correctly in relation to the lower first molar, maintaining an ideal occlusal relationship. However, in Class I malocclusion, there can be misalignment of the anterior teeth. This might manifest in the form of crowding, spacing issues, or an improper bite involving the front teeth that does not affect the overall molar relationship.

Understanding the precise nature of Class I malocclusions helps dental professionals assess treatment options that focus primarily on improving the alignment of the anterior teeth while the foundational occlusive relationship remains intact. This contrasts with other classes of malocclusion, which involve more significant shifts in the molar relationship and often require more complex corrective measures.
