Occlusal Splints and Their Role in TMJ Treatment


Temporomandibular joint (TMJ) disorders have become a prevalent issue affecting a significant portion of the population. These disorders can cause a range of symptoms, including jaw pain, headaches, and difficulty in chewing. One of the conservative approaches to manage TMJ disorders involves the use of occlusal splints. These custom-made dental appliances play a crucial role in alleviating symptoms and promoting the proper functioning of the temporomandibular joint. This article explores the anatomy of the TMJ, common causes of TMJ disorders treatment in Abu Dhabi, and the role of occlusal splints in their treatment.

Anatomy of the Temporomandibular Joint:

The temporomandibular joint is a complex structure that connects the jawbone (mandible) to the skull. It is comprised of the mandibular condyle, the articular disc, and the temporal bone’s glenoid fossa. The joint allows for various movements, including hinge-like opening and closing, as well as sliding and rotational actions during activities such as chewing and speaking. The proper functioning of the TMJ is essential for maintaining oral health and overall well-being.

Causes of Temporomandibular Joint Disorders:

Several factors contribute to the development of TMJ disorders. Among the common causes are:

  1. Bruxism: Teeth grinding or clenching, especially during sleep, can exert excessive force on the TMJ, leading to discomfort and dysfunction.
  2. Malocclusion: Misalignment of the teeth or jaws can disrupt the normal functioning of the TMJ, causing pain and restricted movement.
  3. Trauma: Injury to the jaw, head, or neck can result in damage to the TMJ, leading to persistent problems.
  4. Stress: Emotional stress can contribute to clenching of the jaw muscles, exacerbating TMJ symptoms.
  5. Arthritis: Inflammatory conditions like arthritis can affect the TMJ, causing pain and inflammation.

Role of Occlusal Splints in TMJ Treatment:

Occlusal splints, also known as bite guards or night guards, are custom-fitted dental appliances designed to address various dental and temporomandibular joint issues. These splints play a vital role in the treatment of TMJ disorders by providing support, protection, and promoting optimal jaw alignment. Here are some key ways in which occlusal splints contribute to TMJ treatment:

  1. Stress and Force Distribution: Occlusal splints act as a barrier between the upper and lower teeth, preventing them from coming into direct contact. This helps distribute the forces generated during clenching or grinding, reducing the stress on the TMJ and associated muscles. By redistributing these forces, occlusal splints alleviate the strain on the joint, promoting a more balanced and comfortable bite.
  2. Relaxation of Jaw Muscles: The use of occlusal splints encourages relaxation of the jaw muscles. This is particularly beneficial for individuals with bruxism, as the splint provides a cushioning effect, preventing the intense grinding of teeth. By minimizing muscle tension, occlusal splints contribute to pain relief and can prevent further damage to the TMJ.
  3. Stabilization of the Temporomandibular Joint: Occlusal splints help stabilize the temporomandibular joint by providing a stable and supportive surface for the jaw to rest upon. This stabilization is crucial for promoting healing and preventing excessive movement that can exacerbate TMJ symptoms.
  4. Prevention of Tooth Wear: Individuals with bruxism often experience tooth wear due to the grinding action. Occlusal splints serve as a protective barrier, preventing direct contact between the upper and lower teeth and minimizing the risk of dental erosion. This not only preserves tooth structure but also contributes to overall oral health.
  5. Promotion of Proper Jaw Alignment: Occlusal splints are custom-designed to fit the patient’s specific bite and jaw alignment. By promoting proper alignment, these splints help in retraining the jaw muscles and joints to function optimally. This can be particularly beneficial for individuals with malocclusion or those whose TMJ issues are exacerbated by poor jaw alignment.
  6. Symptom Management: Occlusal splints effectively manage symptoms associated with TMJ disorders, such as jaw pain, headaches, and earaches. By addressing the underlying causes of these symptoms, splints contribute to an improved quality of life for individuals suffering from TMJ issues.


Occlusal splints play a crucial role in the conservative management of temporomandibular joint disorders. By addressing the root causes and symptoms associated with TMJ issues, these custom-fitted dental appliances provide a non-invasive and effective treatment option. Through stress distribution, muscle relaxation, joint stabilization, and the promotion of proper jaw alignment, occlusal splints contribute to the overall well-being of individuals dealing with TMJ disorders. As part of a comprehensive approach to TMJ treatment, the use of occlusal splints offers relief, improves oral health, and enhances the quality of life for those affected by these common and often debilitating conditions.
