A temporomandibular joint (TMJ) splint, additionally regularly known as an occlusal splint or chew guard, is a custom-made oral equipment designed to suit over the enamel of both the higher or decrease arch. Its look varies based mostly on the precise sort, materials, and supposed operate, however usually it resembles a transparent or barely opaque retainer. The system is usually fabricated from a tough acrylic resin, though softer supplies could also be included relying on the affected person’s wants. A well-fitting equipment will cowl all of the enamel within the arch it occupies, offering a secure and even occlusal floor.
The significance of such an equipment lies in its capability to redistribute occlusal forces, defend the enamel from grinding (bruxism), and stabilize the temporomandibular joint. By making a extra ultimate chew relationship, muscle rigidity within the jaw and face may be lowered, assuaging ache and discomfort related to TMJ issues. Traditionally, these units have advanced from easy chew planes to stylish designs incorporating options like anterior ramps or posterior balancing, demonstrating an ongoing effort to refine their therapeutic efficacy.
