ABSTRACT:
An attachment system for securing to a mounting bar a denture having a plastic base formed with a groove. The system has a generally C-section plastic rider engaged over the bar, having an outer surface with a predetermined outside cross-wise dimension, and engaged in the groove. An elastically deformable liner element of a material substantially harder than the plastic of the rider and of the base is imbedded in the base and forms an inner surface of the groove engaging the outer surface of the rider. The liner element defines a mouth opening having an inside width slightly Smaller than the outside cross-wise dimension of the rider so that the rider can only move into and out of the groove with deformation of the rider and/or of the liner element.
