Abstract : Introduction: The purpose of this study was to evaluate the fitness of the removable partial dentures peek framework made using two distinct fabrication techniques (fabricated by milling via CAD-CAM and injection molding technique). Materials and Methods: A total number of 18 samples were used. The specimens are categorized into two major groups., I and II are each composed of PEEK RPD frameworks for a maxillary class III modification 1 Kennedy classification. Group (I): Frameworks produced by milling via CAD-CAM technique.Group (II): Frameworks produced by injection molding technique. Results: For overall framework adaption, group II(produced by injection molding technique) provided the lowest value (least fit), whereas group I (produced by milling via CAD-CAM technique) provided the highest value (best fit).
