Hasegawa Y, et al. – The purpose of this research work was to examine the relationship between the displacement of mandibular condyle/disc due to occlusal splint insertion with splint therapy and changes in discomfort of the temporomandibular joint (TMJ). The scientists indicated that discomfort tended to remit with splint therapy regardless of temporomandibular magnetic resonance imaging (MRI) findings. In patients with unilateral anterior disc displacement and with an apparent organic disorder, such as a joint effusion, the improvement of TMJ discomfort appeared more likely to occur.
