Which occlusal device is primarily used for long-term muscle relaxation?

The stabilization appliance is designed specifically for long-term muscle relaxation. Its primary function is to provide a comfortable occlusal surface that helps to evenly distribute occlusal forces across the teeth. This design minimizes muscle strain and allows the muscles associated with the jaw to relax. By maintaining a neutral and stable occlusal relationship, the stabilization appliance can alleviate the symptoms associated with temporomandibular disorders (TMD) and bruxism, leading to improved muscle function and reduced tension over time.

On the other hand, some of the other devices may serve specific functions but are not primarily aimed at long-term muscle relaxation. The pivoting appliance is typically used in certain situations to enable movement; the anterior bite plane is often used to treat specific occlusal issues or manage bruxism but is focused mainly on the front teeth; and the posterior bite plane might be geared towards altering occlusion or accommodating specific dental conditions without sharing the same long-term muscle relaxation objectives seen with the stabilization appliance.
