| Angle's classification of malocclusion | A classification of different types of malocclusion, based on the mesiodistal relationship of the permanent molars upon their eruption and locking, and comprised of three classes; Class I: normal relationship of the jaws, wherein the mesiobuccal cusp of the maxillary first molar occludes in the buccal groove of the mandibular first permanent molar; Class II: distal relationship of the mandible, wherein the distobuccal cusp of the maxillary first permanent molar occludes in the buccal groove of the mandibular first molar, and further classified as Division 1, labioversion of maxillary incisor teeth, and Division 2, linguoversion of maxillary central incisors, both of which may be unilateral conditions; Class III: mesial relationship of the mandible, wherein the mesiobuccal cusp of the maxillary first molar occludes in the embrasure between the mandibular first and second permanent molars, further classified as a unilateral condition.

| malocclusion | <dentistry> Poor positioning or inappropriate contact between the teeth on closure. Class I Malocclusion: A Malocclusion where your bite is OK (your top teeth line up with your bottom teeth) but your teeth are crooked, crowded or turned. Class II Malocclusion: A Malocclusion where your upper teeth stick out past your lower teeth. This is also called an overbite or buck teeth. Class III Malocclusion: A Malocclusion where your lower teeth stick out past your upper teeth. This is also called an underbite. (08 Jan 1998) |
| malocclusion, angle class I | Malocclusion in which the mandible and maxilla are anteroposteriorly normal as reflected by the relationship of the first permanent molar (i.e., in neutroclusion), but in which individual teeth are abnormally related to each other. (12 Dec 1998) |
| malocclusion, angle class II | Malocclusion in which the mandible is posterior to the maxilla as reflected by the relationship of the first permanent molar (distoclusion). (12 Dec 1998) |
| malocclusion, angle class III | Malocclusion in which the mandible is anterior to the maxilla as reflected by the first relationship of the first permanent molar (mesioclusion). (12 Dec 1998) |
| class III malocclusion | <dentistry> A Malocclusion where your lower teeth stick out past your upper teeth. This is also called an underbite. (05 Mar 2000) |
| class II malocclusion | <dentistry> A Malocclusion where your upper teeth stick out past your lower teeth. This is also called an overbite or buck teeth (05 Mar 2000) |
| class i malocclusion | <dentistry> A Malocclusion where your bite is OK (your top teeth line up with your bottom teeth) but your teeth are crooked, crowded or turned. (05 Mar 2000) |
