Splint therapy is a common treatment for orofacial pain related to the temporomandibular joint (TMJ), but it can be a significant source of confusion for both the dentist and the dental laboratory. This article will help readers to better understand what needs to be examined in order to properly diagnose patients who are suffering from an internal derangement of their TMJs and occluso-muscular issues. Readers will learn about the appropriate splint device options, what can be expected from each treatment, and how the dental laboratory can offer positive and impactful contributions to the process.

Fig 1. This SRS is fabricated for wear on the maxillary arch. The anterior contour allows the separation of posterior teeth in lateral and protrusive movement.

Fig 2. An SRS needs to be fabricated on
facebow-mounted models. It should be fabricated as close to centric relation as possible.

Figure 2

Fig 3. This is an example of initial distal contacts on an SRS orthotic. This is commonly seen when patients present for adjustment visits. This is a positive sign as the condyles are seating in a more superior position.

Fig 5. A short-term occlusal splint can be used for short-term occluso-muscular discomfort and deprogramming. It is large enough that the
patient can take it home.

Fig 6. With a dual arch B-splint in the mouth, the posterior teeth stay separated by the anterior platform. Both arches are fully retained and covered, which prohibits tooth movement. It is large enough that the patient can take it home with them. Photograph of QuickSplint® courtesy

Fig 7. Posterior interferences are noted on the distal teeth. They must be evaluated and removed or muscular activity will remain because of the posterior tooth contact.
