What is a defining characteristic of type two malocclusion?

In type two malocclusion, also known as mesial occlusion or class II malocclusion, a defining characteristic is that the lower jaw (mandible) is positioned further back in relation to the upper jaw (maxilla). This displacement leads to an overbite, which means that the upper teeth are positioned significantly over the lower teeth when the mouth is closed. In this context, saying that the overbite indicates a lower jaw that is too short accurately captures the essence of type two malocclusion. The relationship of the jaws is crucial in diagnosing and understanding this type of malocclusion, as it affects the overall dental alignment and occlusion.

Understanding this condition is essential for appropriate treatment planning, which may involve orthodontic intervention to correct the jaw relationship and improve function and aesthetics.
