[The relationship between loading on the TMJ and occlusal splints]
The primary purpose of this study is to estimate loading conditions on the TMJ with five different occlusal splint.We developed a model that simulated dynamic relationship between dental occlusion,masticatory muscles and TMJ.It is demonstrated that loading on the condyle increases whatever kinds of splints are used.The anterior splint brings about larger loading on the condyle than any other splint.When the ratio force of the muscle on the non pivot is1,left-side pivot split makes loading on left condyle decrease and right increase.It was change on both condyles when posterior teeth are missing including loading, contact and unilateral mastication.
