TMD Theories and Philosophy

Dentists disagree on TMD because they start from different theories. Understanding the three main schools of thought — and what each one gets right and wrong — is the first step toward understanding why GNM offers a more complete answer.

Perspective on muscle balance
Examines pain patterns from trigger points
Muscle changes do not necessarily involve increased EMG activity – hypomobility,
Tight muscles lead to altered TMJ mechanics – altered degenerative changes in joints
Malocclusion can result in tight muscles

Psychological Theory

Most of the symptoms are due to stress, tension or emotional upset
Leads to increased muscular activity
Nocturnal bruxism
Psychological testing – stress related behavior, anxiety and poor coping skills
Eventually bruxism and clenching lead to changes in the dentition and muscles
Leading to TMJ disorders, muscular imbalance and eventual malocclusion.

Malocclusion Theory

Use of splints to prevent premature contact
Relief can be obtained by revising occlusion – Two schools of focus:

Occlusal disharmony causes the muscular dysfunction
TMJ mechanics

Cause of premature contact is due to trigger points in the muscles – Relieve muscles before splinting
Prolonged dental work, stress or trauma – malocclusion can perpetuate trigger point activity
Proprioception/muscle disturbance can cause malocclusion and altered TMJ mechanics
