Abstract

In France, the Public Health Code was amended in 2004, and now allows dentists to treat facial tissues adjacent to the mouth: and hence, they can now bridge the gap between maxillary sinuses and the mouth area by performing hyaluronic acid injection procedures in the perio-buccal soft tissues.

Accordingly, the National Council of the Order of Dental Surgeons authorizes the practice of hyaluronic acid injection for therapeutic use.

In this article, we will define the legal framework for which we will be held liable as it pertains to hyaluronic acid injection procedures.

After explaining the physico-chemical properties of hyaluronic acid, we will study the mechanisms of ageing, the architecture of the face and various methods of injection.

We will look at the indications and counter indications for the use of hyaluronic acid injection, particularly in terms of its therapeutic usefulness for rehabilitating soft tissue when transitioning from a maxillary full-arch prosthesis to an implant born bridge.

Hyaluronic acid makes it possible to offset the lack of buccal margin of the resin-based removable prosthesis.
