Botulinum Toxin for Special Conditions: Gummy Smile – Advanced Points and Indications

  • Rosemarie Mazzuco

The lips are multifunctional structures, both physiologically and aesthetically. The physician who aesthetically treats the lips should become familiar with the functional anatomy of this important structure. Minor changes in shape, mobility, or lip size are easily identified, either positively or negatively. Likewise, the exposure of the teeth during the smile is directly related to the way the person is recognized or interpreted by others. Beauty patterns change over time, but a beautiful smile is timeless.
