Abstract: The present invention discloses a set of dental arches comprising: an upper arch (1) formed by upper anterior (2) and posterior (3) artificial teeth and another lower arch (5) formed by lower anterior (6) and posterior (7) artificial teeth mounted in an orderly fashion on flexible bases (4) and (8) constructed of elastomeric resin in the form of an arch, having a three-dimensional movement capacity to enable adaptation to the anatomy and physiology of edentulous patients; the base material also allows the adjustment of each tooth individually, through changes of position, inclination or alignment, in a simple manner, thus producing custom prosthodontics; its use in the confection processes of removable complete and partial dentures saves time, labor and cost compared to traditional methods.
