[Orthodontic intrusion using mini-screws]

Abstract

Introduction: Dental intrusion has long been considered one of the most difficult movements to induce in orthodontics. Using conventional mechanics, the main difficulty lies in the need to ensure anchorage control, which is highly complicated to achieve, so as to avoid parasitic movements. In this framework, mini-screws have proven to offer a very effective means of anchorage, allowing greater control over intrusion of the anterior and posterior teeth and a simpler biomechanical movement opening up new therapeutic perspectives for the orthodontist.

Objective: The aim of this study was to describe the clinical and biomechanical application of mini-screws for dental intrusion.
