On restorative treatment, it has been used Check bite method to avoid interference on functional movement. Recently, it has been developed and clinically used an articurator with mechanism for condyle path adjustment on working side.
But, inspite of difference between outwards and return course, only one of them, of course outwards path, has been measured.
It is problem that condyle path is changeable according to position and morphology of guiding tooth.
On the other hand, new prosthodontic theory and an articulator have been brought forward to solve the problem.
Now, I presented two cases and discussed, one was treated with traditional theory, the other was treated with new theory, the results as follows ; On traditional check bite method, condyle path had been changed by past of time, and on new theory the same result obtained.
