ABSTRACT The purpose of this study was to evaluate the influence of maxillary arch size on the artificial teeth movement in complete dentures. The maxillary dentures were processed with a barrier-type IV gypsum molding technique, and polymerized by microwave energy. Twenty one dentures were fabricated and equally divided into 3 groups, according to maxillary residual ridge size: G1) small; G2) medium and G3) large size. Reference points were made on the incisal edges of the central incisors and the supporting cusps of the premolar and second molar teeth. Linear distances among reference points, in a horizontal plane, were measured with a computer program (Auto cad 2000) before and after processing denture. Although there were differences between measurements, indicating some movement degree among artificial teeth, the results showed no statistical significantly differences among three groups studied. It was concluded that the maxillary arch size has not influence on the artificial teeth position
