Abstract
In the previous report (the first report) reported was the outcome of splint therapy with a simplified bite-taking splint for patients with toothache, hypersensitivity, and temporomandibular joint disorders, etc, in short, functional disorders perchance due to excessive occlusal force (1st report). The logic of this therapy is supplemented by long-term follow up as over the time course there are many factors involved in the incidence of functional disorders including biological reactions. The age of 10 long-term follow-up patients at the initial visit ranges from 4 to 58 years old. A case of splint therapy involving suspension of an old splint therapy is included. The outcome strongly suggests ①effectivity for early mild symptoms and ② occlusal care in the development period.
