The Marius Bridge was designed and developed by Yvan Fortin.

It is a prosthesis that is termed “fixed detachable”. What this means is that the method of design allows for the teeth to be inserted in such a path, and pins in the side of the mouth are engaged in this double metal substructure making it feel similar to non removable teeth. This is an alternative treatment for those who are seeking a non removable teeth, however lack aesthetic support for their lip.
