Abstract
An extracoronal attachment for a removable partial denture utilizes a joint comprising a fixed ball within a movable resilient tube to connect the prosthesis to the abutment teeth. The attachment is accurately constructed by a kit and applied by a method which insures that tensile and shear stresses otherwise applied to such attachments during functional loading are significantly reduced so that the male retainer may be permanently secured to the abutment teeth by means of an adhesive bond.
