In class II occlusion, what relationship do the mandibular arch and the body of the mandible have to the maxillary teeth?

In class II occlusion, the maxillary teeth are positioned more forward compared to the mandibular teeth. This discrepancy results in the mandibular arch having a bilateral distal relationship to the maxillary teeth. Specifically, the first molars exhibit this positioning, where the lower first molar is positioned further back relative to the upper first molar on both sides of the mouth. This means that in a typical class II relationship, if someone were to look at the alignment of the teeth, both sides would show the mandibular teeth sitting behind the maxillary teeth, hence the classification as a bilateral distal relationship.

Understanding this positioning is essential for dental professionals when assessing occlusion and planning treatment. The distinction also helps in recognizing potential functional issues and may guide decisions regarding orthodontic interventions or restorative work.
