Rotational path partial denture design: a 10-year clinical follow-up--Part I.
A conventional removable partial denture that uses a straight path of placement requires that all rests and clasps be seated simultaneously. The incorporation of a dual, curved, or rotational path of placement permits one portion of the framework to be seated first, followed by the remainder of the framework. This procedure usually permits a reduction in the number of clasps in the framework without compromising the biomechanical properties of the prosthesis. Rotational path designs that eliminate clasps reduce tooth coverage by components and often enhance esthetics, thereby contributing to improved patient acceptance.
