Which of the following does NOT explain why occlusal appliance therapy can help with TMD symptoms?

Occlusal appliances are commonly used in the treatment of temporomandibular disorders (TMD), and understanding their mechanisms is crucial in explaining their benefits. The option that does not explain why occlusal appliance therapy helps with TMD symptoms is linked to the maintenance of the condylar position.

While occlusal appliances can influence condylar positioning to some degree, their primary benefits lie in other areas. For instance, altering the occlusal condition through an appliance can distribute forces more evenly across the teeth and surrounding musculature, potentially alleviating discomfort and improving jaw function. Additionally, an increase in the vertical dimension achieved by an appliance may provide relief by minimizing muscle strain and facilitating a more relaxed jaw position.

Furthermore, occlusal appliances can promote natural musculoskeletal recovery by allowing the musculoskeletal system to rest and heal without excessive loads or grinding forces acting on the jaw, which can lead to symptom relief.

Therefore, the maintenance of the condylar position is less about the direct benefits of occlusal appliance therapy and more about maintaining a state that may not necessarily relate to the complex interactions and muscular adaptations that occur while using such appliances.
