The aim of this study was to fully compare edentulous upper maxilla, linear anatomical measurements, and try to correlate them to different anatomical shapes of the arc (square, triangular and oval), in order to create a database in biomechanical studies. In this retrospective study, 100 dental plaster models of edentulous maxilla were analyzed. First, the maxillas were classified by visual analysis of the arches into three distinct groups: square, triangular and ovoid. Subsequently, guiding points were established: the incisive papilla center(A), posterior limit of the peripheral sealed (P), the higher the posterior region on each side of the tuberosity (T). The models were photographed and the images conveyed to a computer program (Adobe Photoshop®). The anteroposterior measurements (AP), lateral-lateral (TT) and perimeter (P) were measured in a specific program (ImageTool®). For each format, the numbers obtained were: Square (n = 22), triangular (n = 33) and ovoid (n = 48). The averages in millimeters for each format were: Square Arch (AP = 38.03, TT = 46.79, P = 99.07), triangular arch (AP = 38.68, TT = 44.96, P = 96, 52) and ovoid arch (AP = 38.19, TT = 46.26, P = 98.05). The AP extent was greater in ovoid arches, arches TT in squares, and the square perimeter arc. Statistical analysis showed no statistically significant difference between all measurements performed in the comparison between groups
