The goal of this study was to obtain basic data for the clinical evaluation of full dentures, and to investigate quantitatively and three dimensionaly for every phase of mandibular movement, the mobility at the anterior teeth of maxillary full dentures during function. The subjects were seven people having maxillary and mandibular full dentures with goodretention and stability. Measurements were performed during clenching, tapping and mastication. It was found that the maxillary denture moved in a regular pattern together with mandibular movements during tapping and during the middle phase of mastication, and it was possible to establish and measure translation parameters for each phase of mandibular movement. From the results of analyzing the parameters for each translation using three foods, boiled fishpaste, peanuts and dried squid, a significant difference was observed between the amount of anterior/posterior translation after entering the occlusal phase, and the total amount of translation in the lateral and vertical directions.
