Angle's classification of malocclusion (modified)

Etymology: Edward Hartley Angle, American orthodontist, 1855-1930
a classification of the various types of malocclusion. The classification is based on where the buccal groove of the mandibular first molar contacts the mesiobuccal cusp of the maxillary first molar: on the cusp (Class I, neutroclusion, or normal occlusion); distal to the cusp by at least the width of a premolar (Class II, distocclusion); or mesial to the cusp (Class III, mesiocclusion). Each class contains two or more types or divisions. See also classification of malocclusion.
