Biomechanics + TADs: Predictable Results

The introduction of Temporary Anchorage Devices (TADs), safe devices and simple clinical use, has revolutionized the orthodontic world, simplifying otherwise very complex treatments, and making possible treatments otherwise impossible. During the last fifteen years, the use of TADs has deeply transformed our daily orthodontic practice, leading to new protocols and simplified orthodontic biomechanics. Nowadays, TADs are an integral part of orthodontic treatment, especially of complex patients, providing an reliable anchorage and allowing the orthodontists to apply force system which often can not be applied efficiently with conventional mechanics. However, the careful knowledge of the biomechanics and of the different types of movement, according to the point of application of the forces, of the bone and periodontal support, is still an indispensable element for an effective and efficient orthodontic treatment. Indeed, biomechanics principles are ever more important in designing appliances to deliver predictable force system.

Hence, whilst it is of primary importance to know which sites can be preferred for the insertion of TADs, according to the desired movements, on the other hand it is essential to know what kind of movement we will obtain, if it represents what we want or if and how it is possible to optimize it.

This course will describe optimal TADs, their design and optimal insertion places in the oral cavity. Different malocclusions may require a careful selection of best site for TAD insertion for application of desired force system. The lectures will also go over application of one couple force system and cantilevers. Various appliance designs would be presented for treatment of complex malocclusions such as open bites, deep bites, space closure, and interdisciplinary patients.
