Normal 0 false false false EN-US X-NONE AR-SA The theory of designing partial prostheses with rotational path of insertion has been debated for years but most dentists do not consider this treatment method. In conventional partial prostheses, the rests have a single path of insertion while in rotational path of insertion, first the center of rotation sits in the rest then the prosthesis is roated and inserted in final position. In rotational path of insertion prostheses, a rigid retainer is needed as well as conventional clasps. The rigid retainer is inserted in undesirable undercut areas that are not used in conventional method. In current study, methods of rotational partial prostheses as well as their advantages and disadvantages are introduced and discussed.
