Quizplus · Accepted Answer

Angle's classification system for occlusion and malocclusion is based on the relationship between the permanent maxillary first molars and the opposing mandibular first molars. This relationship is used as the starting point for determining the positions of the other teeth in the arches. Therefore, the permanent maxillary first molars are the key to Angle's classification system.
