malocclusion
Pronunciation: mal-oh-KLOO-zhun
Misalignment of teeth or incorrect relation between upper and lower dental arches.
Full Definition
An abnormal alignment of teeth or improper fitting together of the upper and lower dental arches when the mouth is closed. In craniofacial surgery, malocclusion often reflects underlying skeletal discrepancies requiring surgical correction through orthognathic procedures. Classifications include Class I (normal relationship with crowded teeth), Class II (overbite/retrognathic mandible), and Class III (underbite/prognathic mandible). Correction typically involves combined orthodontic and surgical treatment.
Usage
Usage note: Often classified using Angle's classification system (Class I, II, III); ensure proper classification is specified.
