TMJ refers to the temporomandibular joint, where the lower jawbone meets the skull. When the joints are not aligned properly, they can cause pain and tenderness, including the locking of the jaw and limited opening of the mouth. Various types of dentures may be prescribed to provide TMJ pain relief.
Since TMJ is the result of misaligned joints, a stabilisation splint is the most widely recommended orthotic denture for TMJ, according to the National Institute of Dental and Craniofacial Research.
A stabilisation splint is a mouth guard that fits over the upper and lower teeth to correct the way teeth fit together.
The goal of a stabilisation splint is to stabilise one's bite to relieve the muscle spasms and pain associated with TMJ. However, it is just a temporary device to be worn until the bite is stabilised.
Sometimes TMJ is brought about by the constant grinding of the teeth in your sleep, causing stress to the joints. Mayo Clinic suggests using a bite guard to prevent your teeth from grinding together when you sleep.
If your bite is misaligned due to biting surfaces or missing teeth, your dentist may suggest partial dentures, crowns or orthodontics to align the bite.
The type of dentures used depends on the specific needs of each patient. It's best for someone suffering from TMJ to see his dentist or doctor for a specific treatment plan.
