Facial expressions. Facial muscles as part of the neuromuscular system.
The visible part is a muscular disorder

Abstract
Facial expressions represent a key interface between emotional communication and facial aesthetics. Both cosmetology and aesthetic dentistry aim to improve appearance, but neuromuscular dentistry adds a crucial functional dimension by addressing the underlying muscular balance and coordination
that shape facial expressions. Facial muscles are under the control of the central nervous system, which stores specific motor engrams for various emotional states. Any imbalance within the neuromuscular system — including the masticatory, facial, or cervical muscles — may distort these expressions, resulting in asymmetry, tension, or signs of premature aging.
This report explores the integration of facial expression analysis into neuromuscular dental protocols. The Facial Action Coding System (FACS), developed by Ekman and Friesen, provides an objective framework for assessing muscle activity patterns and identifying dysfunctions visible on the face. Clinical
cases will demonstrate how rebalancing occlusion, correcting mandibular position, and normalizing muscle tone through neuromuscular approaches can lead not only to functional improvement but also to remarkable enhancement of facial harmony and expressivity.
By linking dentistry with neurophysiology and facial aesthetics, this work proposes a paradigm shift: the visible aspect of many aesthetic concerns may, in fact, be a manifestation of muscular disorders. The presentation emphasizes diagnostic integration, interdisciplinary collaboration, and the future potential of facial EMG and AI-assisted FACS evaluation in aesthetic and functional dentistry.
Learning Objectives
- To understand the role of facial muscles within the neuromuscular system and their influence on facial aesthetics.
- To learn how the FACS system can be applied in dental diagnostics and treatment evaluation.
- To explore how neuromuscular rebalancing impacts facial expression, symmetry, and emotional communication.
