Study Notes
Angle's Classification Method
-
Class I: Neutrocclusion
- Normal molar relationship according to the maxillary first molar.
- Presenting conditions may include spacing, crowding, over eruption, or under eruption of other teeth.
Class II: Distocclusion
- Defined by upper molars positioned anteriorly to the mesiobuccal groove.
- Mesiobuccal cusp commonly rests between the first mandibular molars and second premolars.
-
Subtypes:
- Class II Division 1: Protruded anterior teeth with the same molar relationships as Class II.
- Class II Division 2: Central incisors are retroclined, with lateral teeth overlapping the centrals.
Class III: Mesiocclusion
- Upper molars are positioned posteriorly to the mesiobuccal groove.
- Mesiobuccal cusp of maxillary first molar lies behind the mandibular first molar's mesiobuccal groove.
- Characterized by lower front teeth being more prominent than upper front teeth.
- Often associated with patients having a large mandible or a short maxillary bone.
