the Functions and Adjustments of Occlusal Splints in Dentistry

Occlusal splint

Doctor, is the height and function of the occlusal splint different? I was mistakenly thought to have a dropped jaw by a massage therapist, and the repositioning maneuver caused me to have temporomandibular joint dysfunction.
A Western doctor made an occlusal splint for me.
I didn't know I needed to have the original doctor adjust the height.
As a result, when I went to have a tooth extracted, the doctor adjusted the height for me.
Now I'm unsure if this will have any impact.
What will happen if I don't wear it? Thank you.

The occlusal splint in the posterior region should have a thickness of 2-3 centimeters to effectively relax the masticatory muscles.
Generally, if the opening of the anterior incisors is less than 20 centimeters, it is functional.
However, if the thickness is too great, it may cause tension in the opening muscles, leading to fatigue and soreness in the masticatory muscles.
Respectfully, Dr.

More Info

Occlusal splints, also known as bite splints or dental splints, are custom-made devices that are typically used to treat various dental and jaw-related issues. They are designed to fit over the upper or lower teeth and serve multiple functions, including alleviating pain, preventing teeth grinding (bruxism), and correcting occlusal discrepancies. Understanding the functions and adjustments of occlusal splints is crucial for effective treatment and overall oral health.

Functions of Occlusal Splints
1. Pain Relief: One of the primary functions of occlusal splints is to relieve pain associated with temporomandibular joint (TMJ) disorders. By providing a cushioning effect, these splints can help reduce the strain on the jaw muscles and joints, leading to decreased discomfort.

2. Protection Against Bruxism: For individuals who grind their teeth at night, occlusal splints act as a protective barrier. They prevent wear and tear on the teeth, which can lead to sensitivity, fractures, and other dental issues.

3. Alignment and Occlusion Correction: Occlusal splints can help in correcting misalignments in the bite. They can be adjusted in height and thickness to ensure that the upper and lower teeth meet correctly, which is essential for proper jaw function.

4. Muscle Relaxation: By altering the position of the jaw, occlusal splints can promote relaxation of the masticatory muscles, which can be beneficial for individuals experiencing muscle tension or spasms.

5. Facilitating Healing: In cases of dental surgery or trauma, occlusal splints can help stabilize the jaw and promote healing by preventing excessive movement.

Adjustments and Height Considerations
The height of an occlusal splint is a critical factor that can significantly influence its effectiveness. If the splint is too high or too low, it can lead to discomfort and may exacerbate existing issues. Adjustments to the height of the splint are often necessary based on the individual’s specific needs and the nature of their dental problems.

1. Height Adjustments: If your occlusal splint was adjusted by a dentist during a dental procedure, it is essential to communicate any changes in your symptoms or comfort level. The height of the splint should allow for a comfortable bite without causing additional strain on the jaw.

2. Impact of Not Wearing the Splint: If you do not wear the occlusal splint as prescribed, you may experience a return of symptoms associated with TMJ disorders, bruxism, or other dental issues. This could lead to increased pain, further wear on your teeth, and potential complications in your jaw alignment.

3. Follow-Up Care: Regular follow-up appointments with your dentist are crucial for monitoring the effectiveness of the occlusal splint. During these visits, your dentist can make necessary adjustments and address any concerns you may have regarding your treatment.

Conclusion
In summary, occlusal splints play a vital role in managing various dental and jaw-related conditions. Understanding their functions and the importance of proper adjustments is essential for achieving optimal results. If you have concerns about the height of your splint or its impact on your dental health, it is advisable to consult your dentist for further evaluation and guidance. Regular communication with your dental care provider will ensure that your treatment plan remains effective and tailored to your individual needs.
