- “Biomechanics and Aligners: Achieving Predictable Outcomes”
- Application of biomechanics principles is very important to achieve predictable results. With aligner treatment delivery of proper force and moments need special care due to lack of anchorage and relative flexibility of material. The biomechanics principles though are same as fixed appliances as teeth may need translation, controlled tipping or uncontrolled tipping. For translation and controlled tipping aligner treatment needs attachments on crowns. The number of attachments on each tooth and their orientation, design and location can deliver a force system to achieve desired results. Case presentations of fixed and aligner treatment will show how biomechanics principles are same for both treatment modalities.
- "Acceleration devices and aligner treatment"
Acceleration of orthodontic tooth movement is highly desired by our profession. We know aligner therapy satisfies our need of esthetics based appliance to correct numerous malocclusions. A faster aligner therapy especially for complicated malocclusions can bring orthodontic treatment to a new level. This presentation will describe state of the art of biology of tooth movement and how as orthodontists we can modulate osteoclastic activity and bone remodeling. Latest information and biologic basis of techniques such as vibration, photomodulation, micro osteoperforation, and lasers will be discussed. Results of our own studies regarding speeding orthodontic treatment will be presented and how aligner therapy can benefit from this information
