The proper relation of the muscle pressure surface form and surrounding tissue is of great importance. Physiological arrangement of artificial teeth using the trial fitness material and Remolding is a new technique to form the functional contour of the denture.In this study, five edentulous patients with different ridge resorption were selected, the extent of tongue space, comfort and function of the complete dentures constructed by the Remolding technique (R-denture) and conventional method (C-denture) were compared.The results were as follows:1. The tongue space of physiological teeth arrangement was significantly larger than that of posterior teeth which were set on the interalveolar ridge line.2. Three of 5 patients evaluated a definite superiority of chewing, speech, stability and inferiority of food accumulation with the R-denture.3. In selecting a set of dentures for regular use, all 5 patients preferred R-denture.4. The masticatory movements of R-denture was better balanced than that of C-denture in chewing rhythm.5. It is suggested from tomographic diagnosis that the triangle area drawn from the maxillary residual ridge crest and mandibular supporting bone is suitable criterion for the arrangement of artificial posterior teeth.
