Orthodontics Anomalies Anomalies of Teeth Groups of teeth Jaws Intermaxilary relationships Anomalies of tooth number  Hypodontics (hypodontia)  Hyperodontics (hyperodontia)  Anodontics (anodontia) Third molars, lateral incisors, premolars (2nd) Anomalies of tooth size (dimension)  Microdontics (microdontia)  Macrodontics (macrodontia) Anomalous tooth form  Dentes confusi, concreti, geminati Cone teeth Anomalies of tooth position  Inclination  Rotation  Transposition  Infraoclusion  Supraoclusion  Vestibular, oral eruption  Diastema Anomalies of group of teeth  Compression  Nonocclusion  Deep bite  Open bite  Retrusion  Protrusion  Inverse bite  Prognatism - overlap Key of occlusion acc. to Angle  Normoocclusion: Mesiobuccal cusp of the first maxillary molar goes between mesial cusps of the first mandibular molar. Key of occlusion acc. to Angle  Normoocclusion (normoocclusia)  Distoocclusion – mandible is in posterior position (distoocclusia)  Mesiooclussion – mandible is in anterior position (mesioocclusia)
