Paediatric Dentistry Course

Abstract:

Recent studies have shown a low efficacy of various tooth movement with thermoplastic aligners. The problem is primarily due to the low elasticity of plastics. A recent invention of a resin has allowed shape memory characteristics with aligners just like memory arch wires. No attachments are needed as force is delivered by sequentially changing the shape of the teeth needing movement. These aligners can also be made in direct printing or by laboratories. This presentation will discuss evidence-based studies on shape memory material, biomechanics and easy process in making them. Clinical cases will be presented to describe software management, staging and management of various malocclusions.

Introduction:

Aligners are widespread and routinely used in orthodontics. With 3D printing entering private in-office
settings and becoming widespread and commonly used, the desire for 3D print aligners was massive. For
a few years, different research groups, scientists, and companies have been investigating and evaluating possibilities to create materials for 3D printing of aligners – the shell, not the model – and moving away from vacuum forming. They have now become a reality.

Learning Objectives:

1. To understand limitations of thermoplastic aligners
2. To learn biomechanics of Aligners
3. To learn basic concepts of shape memory aligners (SMA)
4. To understand software and treatment planning of SMA’s
5. To learn staging and correction of various malocclusions

Who should attend:

1. General Practitioners
2. Orthodontists
3. Ortho Post Graduate Students
4. Orthodontic Residents
