The use of a rotational-path design for a mandibular removable partial denture

The lack of display of anterior metal clasps is a primary advantage of the A-P rotational-path mandibular RPD design. A disadvantage of this design is that it relies on rigidmetal guiding plates for anterior retention and stability. Loss of retention may require procedures much more involved than the simple adjustment of conventional RPD clasps. Proper adherence to design, survey, fabrication, and adjustment procedures described by the authors should result in an esthetically pleasing and well-retained tooth-supported removable prosthesis. This article recommends the A-P rotational-path mandibular RPD as a treatment the clinician can use to restore multiple missing anterior teeth and satisfy a patient's financial, esthetic, and functional requirements.
