Abstract

The tests on the oral capacties which are divided into five groups on centric occlusion position, physiologic rest position, two mm open bite position, four mm open bite position, and maximum opening position of the mandible were conducted on the one hundread normal dental college students and staffs. The aims were to study the changeability of the fundamental oral structure, to get some helpful informations for the full denture wearers and related physiology, and also to find out further experimental standards. The results were as follows; 1. There was also some volumetric space in centric occlusion position. 2. The greater the voluntary opening degree of the mandible was, the greater the oral volumetric capacity was. 3. There were no correlations between the oral capacity and height, weight, and cheek thickness. 4. There were no correlations between the centric occlusion position and physiologic rest position, and voluntary positions of the mandible. 5. The inserted material into the oral cavity was much influential to the physiologic rest position.
