What does Angle's classification 1 indicate?

Angle's classification is a widely accepted system for categorizing dental occlusion and malocclusion, developed by Edward Angle in the early 20th century. When considering Angle's classification, Class 1 indicates a normal occlusion where the first molar of the maxillary arch occludes with the first molar of the mandibular arch in a specific manner.

In Class 1 occlusion, the mesial cusp of the maxillary first molar fits into the buccal groove of the mandibular first molar. This positioning facilitates a proper intercuspation, allowing for effective chewing and function. Hence, it is associated with a balanced alignment of the teeth and typically does not exhibit significant overjet or overbite issues.

The other classifications indicate various forms of malocclusion, which blur the lines of this ideal occlusal relationship. Therefore, recognizing Class 1 as a 'normal bite,' characterized by this specific relationship between the molars, is crucial for understanding the fundamentals of dental occlusion in the NEBDN context.
