Mesialization
Pronunciation: MEE-zhul-ih-ZAY-shun
The orthodontic movement of a tooth or teeth in a mesial (anterior) direction along the dental arch.
Full Definition
Mesialization is the controlled movement of one or more teeth toward the midline or in the anterior direction within the dental arch. It is employed in a variety of clinical scenarios, including closing extraction spaces by moving posterior teeth mesially, correcting Class III molar relationships, or replacing missing teeth through orthodontic space closure. Mesialization requires careful anchorage planning to prevent undesirable reciprocal movement of adjacent teeth. Editors should use the American English spelling 'mesialization' (not 'mesialisation') and should clearly distinguish this term from 'mesial drift,' which refers to the natural physiological tendency of teeth to migrate anteriorly over time.
Usage
Usage note: Preferred American English spelling: 'mesialization.' Distinguish from 'mesial drift,' which is a passive physiological process, not an orthodontically induced movement.
In Context
- "Mesialization of the lower second molar was planned to close the space created by the extracted first molar." — Orthodontic treatment plan
- "The term 'mesial drift' was used where the author meant 'mesialization'; the editor clarified that the movement was actively induced." — Manuscript review note
