Redefining the envelope of discrepancy with temporary anchorage devices refers to the use of mini-implants, mini-plates or mini-screws in orthodontics to expand the range of possible tooth movements and correct complex dental discrepancies. This allows for more efficient and effective treatment of complex malocclusions, including retraction of teeth, correction of severe crowding, open bites, deep bites, and cases with missing teeth. Temporary anchorage devices allow orthodontists to have greater control over tooth movements, as they provide stable and reliable anchorage points. They minimize the dependence on patient cooperation since they provide additional anchorage independent of patient compliance. They can accelerate treatment by allowing orthodontists to move teeth more efficiently and effectively. Thus, treatment duration can be shortened, reducing the overall time patients spend in braces or aligners.
