|March 1, 1979
Summary
Mandibular movements are guided by teeth, joints, and muscles. Understanding their interplay and defining terms like "central occlusion" is key to diagnosing and treating orofacial pain-dysfunction syndromes.
Area of Science:
- Dentistry
- Biomechanics
- Orofacial Health
Context:
- Mandibular movements are governed by a complex interplay of tooth, joint, and muscle guidance.
- Existing terminology for occlusal relationships and muscle function lacks clarity and precise definitions.
- Orofacial dysfunction often presents with pain, but the underlying etiological factors can be multifactorial.
Purpose:
- To propose clear, delineated definitions for "central occlusion", "central relation", and "muscle guidance".
- To elucidate the interrelationships between tooth, joint, and muscle guidance in controlling mandibular position and movement.
- To advocate for the term "pain-dysfunction syndrome" as a more accurate descriptor for orofacial impairments.
Summary:
- The study defines three primary guiding factors of mandibular motion: tooth, joint, and muscle guidance.
- It emphasizes the importance of biological equilibrium between these factors for harmonious structure and function.
- Deviations in these factors can lead to occlusal disorders and orofacial dysfunction, with pain being a key symptom.
Impact:
- Provides a framework for analyzing and understanding occlusal disorders and orofacial pain.
- Promotes more accurate diagnosis and terminology, moving away from terms like "Costen's syndrome".
- Contributes to a better understanding of the biomechanics of the temporomandibular system and its clinical implications.
