In Class II occlusion division 1, what is the positioning of the maxillary anterior teeth?

In Class II occlusion division 1, the maxillary anterior teeth are characterized by a proclined position. In this classification, the first molars exhibit a specific relationship: the maxillary first molar is positioned more towards the back of the mouth compared to the mandibular first molar, leading to a situation where the upper front teeth lean towards the lips. This proclination is a typical feature of Class II division 1, where not only are the maxillary incisors angled facially, contributing to a more prominent appearance, but there is also often an increased overjet and a significant overlap of the upper teeth over the lower ones.

In contrast, the other options describe different dental relationships not characteristic of this classification. For instance, if the maxillary anterior teeth were retruded, it would indicate a different occlusal relationship, possibly aligning more with Class II division 2 or other malocclusions. Additionally, being aligned with the mandibular incisors or occluding with the buccal groove suggest different positional relationships that do not hold true for this specific occlusal classification.
