Distalization
Pronunciation: dis-tuh-ly-ZAY-shun
The orthodontic movement of teeth in a posterior (distal) direction, most commonly applied to upper molars to create space or correct a Class II molar relationship.
Full Definition
Distalization refers to the controlled bodily or tipping movement of one or more teeth away from the midline in a distal direction. It is frequently achieved using intra-oral devices such as the Pendulum appliance, Jones Jig, or temporary anchorage devices (TADs), or extra-orally via headgear. The term appears in treatment plans, clinical letters, and orthodontic journals. Editors should note the British spelling 'distalisation' versus the American 'distalization'; the variant used should be consistent with the target publication's style. It is not synonymous with 'extractions,' which also create space but through tooth removal.
Usage
Usage note: Check spelling variant (-ize vs -ise) against house style and apply consistently. Not interchangeable with extraction-based space creation.
