Thanks to Augmented Reality, you will be able to watch videos of the most important stages of clinical cases presented in this special issue.

The free "Quintessence Special" application is an essential new feature and complement to the Quintessence Special magazine. It can be used without an Internet connection, on a tablet or smartphone.

The steps illustrated by a video are identified in the journal by a pictogram.

Fly over the designated illustrations with your tablet or smartphone to play the corresponding clinical video.

Each video can be viewed without time limit, in any order, as soon as it is triggered by the corresponding pictogram.
