Complex cases: approaching the anterior open-bite

Abstract
Anterior open-bite cases are known to be difficult to treat satisfactorily because of their multifactorial etiology and their high relapse rate. Depending on the cause, patients age and functional issues, several treatment approaches can be used and Aligners, if properly applied, can be highly effective in achieving a stable, esthetic and functional good final result.

By using aligners only or combining them with auxiliaries or in a multidisciplinary approach, we can address from the most simple anterior open-bite to the most severe and complex one. A characteristic that we need to respect in all the cases we plan is the correct sequencing of movements and that is specially true when working with aligners. Biomechanics is the key and it always needs to be planned in respect for the biological principles of the tissues, soft and hard.

Efficient Planning of Clear Aligner Therapy with Invisalign System in Treating Class II Deep Bite Malocclusion in Adults and Teenagers

Abstract
Clear aligner therapy has revolutionized modern orthodontics, offering a combination of aesthetics, precision, and patient comfort. In this presentation, we will explore how the Invisalign system provides an efficient and predictable solution for managing Class II deep bite malocclusions in both adult and teenage patients.

The discussion will focus on key aspects of treatment planning:

• Accurate diagnosis and digital workflow integration using advanced technologies
• Strategies to ensure compliance and track progress in adolescent patients
• Evidence-based approaches for managing occlusal contacts and overjet reduction

Real-life clinical cases will illustrate step-by-step planning, highlighting how digital simulation tools enhance treatment efficiency and predictability. This session aims to provide practitioners with actionable insights into achieving functional and aesthetic outcomes while maintaining efficiency in their orthodontic practices.
