What Causes Temporomandibular Disorder?

Temporomandibular Disorder (TMD)

Understanding TMJ Dysfunction

Temporomandibular Joint (TMJ) dysfunction is a complex musculoskeletal disorder that can cause various types of discomfort, affecting many aspects of daily life. This condition arises from a combination of factors impacting the jaw joint and its associated muscles.

Causes of TMJ Dysfunction

TMJ dysfunction arises from various factors that impact the musculoskeletal system. It’s a multifaceted disorder with diverse causes, including:

• Masticatory muscle dysfunction
• Derangement or displacement of the TMJ articular disc
• Nocturnal teeth grinding (bruxism) leading to heightened TMJ pressure and uneven movement
• Occlusal problems such as poor bite, asymmetry, or retrognathic conditions

Additional contributing elements consist of:

• Secondary mandibular misalignment due to orthodontic treatment or occlusal appliances
• Wisdom teeth extraction
• Prolonged mouth opening during dental procedures
• Poor cervical posture
• Myofascial pain
• Neuropsychological factors
• Stress
• Less common triggers like whiplash, trauma, infection, polyarthritic conditions, tumours, and anatomical irregularities

Categorising TMJ Dysfunction

To better manage TMJ dysfunction, it’s essential to classify it into distinct clinical categories. These classifications include:

1. Painful jaw muscle movement
2. Articular disc displacement
3. Arthralgia or arthritis

Each category represents a facet of the dysfunction that can arise within the TMJ structure. Understanding these classifications helps healthcare professionals develop targeted treatment plans tailored to each individual’s specific symptoms and needs.

Common Symptoms of TMJ Dysfunction

TMJ or jaw discomfort stems from multifaceted origins. Two primary culprits stand out: abnormal jaw opening or closing.

• Irregular Opening: Most TMJ dysfunction cases involve incomplete or uneven jaw opening. Fortunately, physiotherapy assessment and intervention yield positive outcomes in these instances, as teeth occlusion isn’t a concern.
• Abnormal Closing: Closing issues can stem from both teeth occlusion and TMJ incapacity to close seamlessly. If it’s primarily joint stiffness or muscle timing, physiotherapy proves highly effective. However, occlusion-related matters may require evaluation by a dental surgeon to assess bite alignment.

What Causes Jaw Clicking?

Jaw clicking signifies articular disc displacement and is often managed by a TMJ physiotherapist. Clicking might occur while opening, closing, or both. It’s important to seek assessment from a TMJ physiotherapist for a precise diagnosis and a tailored treatment plan.

Conclusion

TMJ dysfunction is a multifaceted condition that stems from a combination of intricate factors impacting the temporomandibular joint. From muscle dysfunction to occlusal problems and various contributory elements, the causes of TMJ dysfunction are wide-ranging and interconnected. By understanding these underlying causes and classifications, individuals and healthcare practitioners alike can better navigate the complexities of this condition. Whether through physiotherapy, dental assessment, or other interventions, addressing the multifaceted origins of TMJ dysfunction holds the key to alleviating discomfort and enhancing quality of life.

What to Do?

If you experience symptoms of TMJ dysfunction, consider seeking the professional advice of your physiotherapist. They can provide a thorough assessment and develop a treatment plan tailored to your needs.
