Angle's classification of malocclusion (modified),
n.pr a classification of the different forms of malocclusion. See also malocclusion.
Class I,
n the normal anteroposterior relationship of the mandible to the maxillae. The mesiobuccal cusp of the permanent maxillary first molar occludes in the buccal groove of the permanent mandibular first molar.
Type I,
n.pr dentition in linguoversion.
Type II,
n.pr with narrow arches; labioversion of the maxillary anterior teeth and linguoversion of the mandibular anterior teeth.
Type III,
n.pr with linguoversion of the maxillary anterior teeth; crowded; lack of development in the proximal region.
Class II,
n.pr the posterior relationship of the mandible to the maxillae. The mesiobuccal cusp of the permanent maxillary first molar occludes mesial to the buccal groove of the permanent mandibular first molar.
Division 1,
n.pr with labioversion of the maxillary teeth.
Subdivision,
n.pr signifies a unilateral condition.
Division 2,
n.pr with linguoversion of the maxillary central incisor teeth.
Subdivision,
n.pr signifies a unilateral condition.
Class III,
n.pr the anterior relationship of the mandible to the maxillae, may have a subdivision. The mesiobuccal cusp of the permanent maxillary first molar occludes distal to the buccal groove of the permanent mandibular first molar.
Type I,
n.pr with good alignment generally but arch relationship abnormal.
Type II,
n.pr with good alignment of the maxillary anterior teeth but linguoversion of the mandibular anterior teeth.
Type III,
n.pr an underdeveloped maxillary arch; linguoversion of maxillary anterior teeth; good mandibular alignment.
