The ideal functional occlusion: A contemporary opinion

Whenever we are involved in tooth displacement, we must refer to an occlusal concept. There are several, the most used remains that of gnathologists: the canine protected occlusion. In this concept, the upper canine has the privileged role of guiding the laterality movement on its own, without the participation of the other teeth. However, some authors in literature reviews believe that the concept of canine protected occlusion or even that of group function occlusion is without any real scientific basis. They were primarily proposed for the clinical simplification they represent. The aim of this work is to discuss our knowledge on the general topic of functional occlusion in order to be able to make evidence-based treatment decisions.
