Class II malocclusion camouflage in adult patients using clear aligners

- Indications and contraindications to an aligner treatment of Angle class II adult patients- Protocols for symmetric cases- Protocols for asymmetric cases- The biomechanical foundation of different movements- The biomechanical effects of class II elastics- Limits of aligner treatment and how to overcome them- The most common mistakes in treatment planning and how to avoid them

Class II malocclusion is one of the most frequent orthodontic problems, with a prevalence of about 40% in our population; therefore, the effectiveness of the different therapeutic options is one of the most debated topics in the literature, with the most controversial results.

The purpose of this presentation will be to discuss the rationale of the clear aligner treatment of adult patients with class II malocclusion.

Using an evidence based approach, the relevant literature will be summarized; furthermore, through numerous clinical cases, the bases of the main mechanics used for an efficient sagittal correction in patients with class II division 1, division 2, and subdivision will be discussed step by step.

In particular, the two currently most used staging protocols will be reviewed, namely the distalization, referring to tooth-by-tooth sequential distal movement, or the jump simulation, representing the simulation of the effect of class II elastics.

Finally, the keys to clinical success and the main mistakes to be avoided will be analyzed.
