Learning to smile: the neuroanatomic basis for smile training

Area of Science:

• Neurology
• Musculoskeletal System
• Facial Anatomy

Background:

• A smile is primarily recognized in the oral and periorbital regions.
• Understanding the underlying neurologic and musculoskeletal elements provides deeper insight into smile mechanics.
• Complex neuromuscular activities, like smiling, benefit from repetition and training of neural and muscular networks.

Purpose of the Study:

• To demonstrate how functional knowledge of smile muscles and targeted exercises can help clinicians assist patients.
• To provide clinicians with evidence-based methods to improve smile aesthetics.
• To enable clinicians to explain the efficacy of smile exercises based on neuro-muscular principles.

Main Methods:

• Analyzing the neurologic control and musculoskeletal components of a smile.
• Developing a set of simple, effortless exercises targeting specific smile muscles.
• Educating clinicians on the anatomy and function relevant to smile improvement.

Main Results:

• Clinicians can gain insight into smile complexities through understanding neuro-muscular aspects.
• Repetitive exercises can train the central nervous system and muscular networks for efficient smile performance.
• Patients can modify behaviors used to camouflage perceived oral flaws through guided exercises.

Conclusions:

• Functional knowledge of smile muscles combined with exercises empowers clinicians to help patients alter camouflage behaviors.
• This approach offers a medically evidenced method for improving smile aesthetics by retraining neuromuscular pathways.
