Abstract

A technique for applying the overdenture concept to removable partial denture construction has been presented. Endodontically treated abutments are prepared with cast gold posts and copings over which removable partial dentures with conventional components are fabricated. No special materials or complicated laboratory techniques are required, and the maintenance and repair problems of precision attachments are avoided. A variety of potential uses and advantages of the technique are discussed.

Retention for a removable partial denture.

This article addresses the complex nature of retention in a removable partial denture. Retentive features range from magnets and springs to clips, clasps, and interfacial surface tension. The retentive quality of an extracoronal clasp varies with the alloy, physical form, location on the abutment, and positional relationship to other elements. Surveying to identify both occlusogingival and mesiodistal undercuts when the path of random dislodging forces are not definitely controlled is needed for effective retention. Augmentation of ineffective retention in existing clasps should concentrate on methods of deepening the undercut or increasing the suprabulge. Tightening of clasps already in contact with a tooth frequently produces adverse changes.
