Abstract
Use of Mini-Screws for Uprighting Movement and Hands-on Modeling on Typodont
The orthodontist often faces the challenge of correcting a tilted tooth through uprighting movement. This may occur, for example, when the premature loss of a first molar causes the second molar to tip, or when the third molar, due to its eruptive path and lack of space, becomes impacted. The inclination of a tooth can hinder proper prosthetic rehabilitation and also predispose the tilted tooth to periodontal problems.
Several uprighting techniques have been described in the literature: alongside the classic methods relying exclusively on dental anchorage, in recent years techniques exploiting skeletal anchorage with mini-screws have been introduced. The biomechanics of uprighting movement are highly complex due to the many variables involved: along with tooth uprighting, space closure or opening may be required, as well as extrusive movement or vertical control of the tooth being corrected.
The course aims to explore the biological and biomechanical issues related to tilted teeth, through both a theoretical section and practical exercises on typodonts. Participants will acquire skills in designing and managing uprighting mechanics with both dental and skeletal anchorage. Special attention will be devoted to the use of the Sander spring, a fundamental tool for achieving effective control of tooth movement.
At the end of the course, participants will be able to approach and manage orthodontic cases requiring uprighting techniques with greater confidence.
