Clinical Presentation of Temporomandibular Disorder (TMD) Practice Test

Using a stabilization occlusal splint to unload the TMJ is a common non-surgical approach. This appliance sits over the teeth to distribute biting forces more evenly and separate the upper and lower arches. By evening out contacts and reducing parafunctional activities like clenching and grinding, the joints experience less mechanical stress during both function and rest. That decrease in load can lessen pain, reduce muscle overactivity, and protect the joint surfaces from further stress, making it a first-line non-invasive option before considering procedures that alter bone or require surgery.

The other options aren’t aimed at reducing joint loading in a non-surgical way: radiation therapy isn’t a treatment for TMD-related joint loading; antibiotics target infection rather than mechanical or muscle stress; orthognathic surgery is a surgical approach that changes jaw alignment and is not a non-surgical method for unloading the joint.
