This course will deal with many general and essential aspects in Biomechanics, focussing on problems that can be encountered by the orthodontist in everyday practice.
Among others, we will cover the topics of arch alignment, posterior teeth uprighting, space closure, and vertical movements, with and without the use of TADs.
On the workshop day, the participants will be specifically trained in bending passive wires, and cantilever systems.

2 Day Course: A Guide to Rational and Predictable Biomechanics
Time: Registrations from 8:30 - Lectures: 9.00-13.00 and 14.30 - 17.30
Standard appliances, including conventional twin or self-ligating brackets and continuous archwires, are used in the majority of orthodontic treatments. The widespread adoption of these techniques is largely due to their ease of learning, as they follow a "recipe" system. Cases are categorized (e.g., Class II, crowding, high angle), and a specific sequence of materials and actions is prescribed for each category. The idea is that the bracket prescription, which contains all the necessary information, will ideally lead to the correct final position of the teeth.
However, the standard approach to orthodontic treatment has several shortcomings due to the significant variability of orthodontic problems, making each case unique. As a result, the recipe approach is a reasonable compromise in many cases, where growth and function also contribute to the therapy's success. Yet, in more complex cases, the standard approach can lead to unpredictable and undesired outcomes. In such instances, a more individualized therapy is required, involving a detailed analysis of the problems and a customized treatment plan and mechanical design.
In this 2-day course, we will discuss the reasons for potential failures and inefficiencies in using standard techniques. We will explore how to avoid side effects and make therapy outcomes more predictable and efficient through the use of rational and individualized mechanics. This alternative approach, based on a deep understanding of orthodontic biomechanics, ultimately extends the capabilities of orthodontic therapy and allows for the controlled treatment of very complex cases.
You will learn some essential concepts about.
- Force System and Dental Movement
- Understanding the statically indeterminate mechanics of a continuous archwire.
- The role of friction in dental movement determination
- How inconsistencies are generated using a continuous archwire
- The “Force Driven” mechanics as an alternative to “Shape Driven”
- Anchorage Analysis and Management
- Basic concepts of statically determinate appliances as cantilevers
- Mechanics Design Examples for Statically Determinate Appliances with Clinical Cases.
Workshop: Cantilevers Mechanics (Thursday 13 and Sunday 16)
