What is typically noted about teeth in Class 2 Division 1?

In a Class 2 Division 1 malocclusion, one of the key characteristics is that the mandible is positioned further back than normal compared to the maxilla (upper jaw). This positioning leads to a significant overjet, where the upper front teeth (maxillary incisors) are often protruded, and when the mouth is closed, they can appear to be positioned much further forward than the lower incisors.

The positioning of the mandible relative to the maxilla is critical in classifying dental occlusions, and in this scenario, it is the retruded position of the mandible that is indicative of Class 2 Division 1. Recognizing this positioning helps dental professionals diagnose and plan appropriate treatments for orthodontic issues.

The other options do not accurately reflect the characteristics of Class 2 Division 1. For instance, the lower jaw being more forward does not apply, nor does the arrangement where the upper incisors sit directly above the lower incisors, as this situation describes a more Class 1 occlusion or a neutral occlusion. Additionally, crowding can occur in Class 2 Division 1, so saying there is no crowding does not align with the typical presentation of this class of malocclusion. Understanding
