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 .
