What is Duchenne smile

There are two types of smiles: the ordinary smile and the Duchenne smile.

An ordinary smile involves only the lips and the muscles around the mouth. A Duchenne smile, however, engages not only the lips but also the muscles around the eyes, creating a warm, genuine expression.

A Duchenne smile is more than just a facial expression—it is a smile that comes from the heart, reflecting true happiness and true emotion.

The reason a genuine smile is called a “Duchenne smile” is that Duchenne was a French scientist who made significant contributions to research on smiles. By studying the muscles that work in the face when a person smiles, he discovered that in a genuine smile, not only the lips but also the eyes and the muscles around the eyes are engaged. In honor of him, that true, heartfelt smile was named the “Duchenne smile.”

Since the goal of our treatment is to provide a “Duchenne smile,” and also to honor Duchenne, who researched smiles, we have named the full-mouth implant treatment “Duchenne Smile” treatment.
