CLASSIFICATION OF SKELETAL AND DENTAL MALOCCLUSION: REVISITED
• Class III type 3b: Negative overjet but patient can make edge to edge( pseudo Class III). The author believes that incisor classification could also be used for esthetic considerations. 4.4. Canine’ s Classification( Fig. 3) Class I: mesial incline of the upper canine overlaps the distal slope of the lower canine( The maxillary canine occludes between the mandibular canine and 1 st premolar). Class II: Distal slope of the maxillary canine occludes or contacts the mesial slope of the lower canine. Class III: The mandibular canine is displaced anterior to the maxillary canine with no overlapping.

4.5. Molar’ s Classification( Fig. 4) The author modified Angle’ s classification to include different molar relationship on both sides and renamed the subdivision. Class I: The mesio-buccal groove of the mandibular 1 st permanent molar occludes with the mesiobuccal cusp of the Maxillary 1 st permanent molar. Class II: The mesio-buccal groove of the mandibular
1 st permanent molar lie posterior to the mesiobuccal cusp of the Maxillary 1 st permanent molar.
• Class II ½ unit: When the maxillary 1 st permanent molar cusps occlude with the mandibular 1 st permanent molar cusps in an edge to edge.
• Class II full unit: When the maxillary 1 st permanent molar cusps occlude anterior to the mandibular 1 st permanent molar.
