There is often a dysfunctional dimension with poor oral habits and parafunctions in the etiology of malocclusions. A multidisciplinary care seems essential.

Materials and Methods

Through a review of the literature, this article analyzes old and current theories on the origin of parafunctions and the therapeutic possibilities for their correction.


Our therapeutic approach to correct these parafunctions must take into account the behavioral approach, which can have a beneficial effect, but also the neurobiological approach.


The current evolution in neuroscience now allows us to better understand the origin of these parafunctions and facilitate a better approach for their correction through behavioral methods. Taking into account the psychological and blood pressure dimension of our patients increases the chances of success. The use of removable or fixed devices can complete this therapeutic approach.
