[The distribution of pressure on the denture supporting tissue and the possibility of determining the point of application of the biting force].

To protect the denture supporting tissue, it is important to make the pressure distribution on the tissue itself proper. Therefore, it is necessary to give the proper occlusal contact. We have not seen any reports on the occlusal contact which produces the proper pressure distribution on the denture supporting tissue. In this report we studied if the point of application of the biting force given by the occlusal contact can be obtained in the distribution of pressure on the denture supporting tissue. We had a patient missing the first and second molar on the right lower jaw to test. We placed four diaphragm pressure sensors flush with the surface of the denture base. The nine fiducial points were placed on the occlusal table of the denture to obtain the point of application of the biting force. To summarize the results: 1. We got the methodical change between the position of the fiducial point and the ratio of pressure on the denture supporting tissue. 2. If the position of the fiducial point was not changed, the ratio of pressure was constant regardless of the load in the region of 05kg. 3. We could estimate the point of application of the biting force given by the distribution of pressure on the denture supporting tissue.
