Types of TMJ Splints


Types of TMJ Splints

When it comes to temporomandibular joint (TMJ) disorders, splints can help stabilize the jaw to alleviate pain and discomfort. Occlusal splint therapy, or simply TMJ splint therapy, employs three different kinds of splints, including permissive, and non permissive.


The most common type of occlusal splints, the permissive splint allows the muscles to seat the jaw joints in their sockets, helping prevent bite disharmony. Permissive splints, which include bite planes and stabilization splints, can be fitted to the upper or lower teeth. With these types of splints, the biting surface is smooth and flat, letting the teeth glide unimpeded and the jaw to close and slide freely to achieve a more balanced resting point.


Directive, or nonpermissive, splints are designed with ramps or indentations that limit the movement of the jaw. Examples of nonpermissive splints include anterior repositioning appliances (ARA) and mandibular orthotic repositioning appliances (MORA). Whereas permissive splints clear the malocclusion – or the misalignment of the teeth and jaws – directive splints prevent full seating of the joints by positioning the jawbone into a forward posture upon closure.
