Maxillary Molar Distalization with Mini-screw Implant Supported Appliances

Orthodontic treatment of Class II malocclusion in terms of maxillary molar distalization can be very challenging by the use of conventional modalities, especially in patients with poor compliance. In these cases, noncompliance approaches can be used, however with a number of unwanted side effects, which diminish their clinical effectiveness. Miniscrew implants, can be used as temporary anchorage devices (TADs) to enhance anchorage and, if properly used, to counterbalance these shortcomings. This lecture will present through various clinical examples the basic principles and the rationale of noncompliance maxillary molar distalization, and will discuss the latest evidence-based data available regarding the effectiveness of the use miniscrew implants as temporary anchorage devices not only to support maxillary molar distalization, but the comprehensive treatment of Class II malocclusion as well.

Learning Objectives:

• Demonstrate the use of miniscrew implants to distalise maxillary molars.
• Understand the biomechanics and to be aware about the advantages and potential complications of the different distalization systems that are supported by mini-implant anchorage.
• Evaluate in an evidence-based manner the efficiently the different distalization systems that are supported by mini-implant anchorage.
