Precision attachment removable partial dentures.

Abstract

Although added preparations and skill are required to provide precision attachment removable partial dentures, more favorable esthetics and load distribution may outweigh the disadvantages. Basic design principles, categories (intracoronal, extracoronal, stud, bar and plunger) and selection of precision attachments are reviewed.

Load transfer by a maxillary distal-extension removable partial denture with cap and ring extracoronal attachments.

This study photoelastically compared the stress distribution characteristics of maxillary, bilateral, distal-extension removable partial dentures retained by light and heavy ERA extracoronal attachments. One prosthesis included supporting rests and the other had no rests. Both designs were tested with and without abutment splinting. The most favorable stress distributions were obtained with light retention elements, supporting rests, and splinting of the abutments. In this configuration the attachment prosthesis compared favorably in stress distribution with the maxillary I-bar retained removable partial denture in a previous study that used a comparable maxillae model.
