As the number of aged people in the world is growing, the need to provide patients with tooth alternate through removable partial dentures is equally growing. There are adversarial effects that should be kept in mind which might disturb the remaining teeth; specially, the abutments and the supporting tissues. These effects might spread to the muscles of mastication and also to the supporting periodontal tissues. Thus, we should plan removable partial dentures (RPDs) without mutilation to the adjacent teeth or the underlying tissues.
