Tooth preparation … An optimal RPD path of placement, guided by mutually parallel guide planes, ensures that the RPD flanges fit intimately over edentulous ridge structures and that the framework fits intimately with guide plane surfaces, which prevents food collecting empty spaces between the intaglio surface of the framework and intraoral surfaces, and ensures that RPD clasps engage adequate numbers of tooth undercuts to ensure RPD retention. Fundamentals of CAD/CAM Computer aided design and manufacturing (CAD/CAM) technology has already revolutionised the field of dental restoration. Write. Previous mathematical modeling studies evaluated only the total surface area. It also considers the relative merits and limitations of these connectors. (1) A high survey line may also result in deformation of the clasp because, on insertion, the clasp is prevented from moving down the tooth by, contact with the occlusal surface.
