Malocclusion
Pronunciation: mal-uh-KLOO-zhun
Any deviation from the ideal alignment and occlusal relationship of the upper and lower dental arches. Classified by Angle's system into Class I, II, and III types.
Full Definition
Malocclusion refers to a misalignment or incorrect relationship between the teeth of the upper and lower dental arches when the jaws are closed. It is traditionally classified using Angle's classification system into Class I (normal molar relationship with crowding or spacing), Class II (retrognathic lower jaw or prognathic upper jaw), and Class III (prognathic lower jaw). Editors encountering this term should note its consistent lowercase styling and single-word form. It is a foundational diagnostic term in orthodontic records, referral letters, and clinical notes.
Usage
Usage note: Always lowercase unless beginning a sentence. Do not hyphenate. Avoid substituting with the informal 'bad bite' in clinical documents.
