Direct retainers for distal-extension removable partial dentures.

The effects of loading locations and direct retainers on the movements of the abutment tooth and denture base of removable partial dentures.

The purpose of this study was to evaluate the degree and amount of movement of the abutment tooth and denture base influenced by the direct retainer of distal extension removable partial denture and the location of functional loading, then to suggest direct retainer design with minimal adverse effect and with optimum functional loading location for residual tissue. The displacement of the abutm...

Indirect Retention Revisited: Risks, Benefits and Paradigm-shift in Removable Partial Dentures

The clinical success of removable partial denture (RPD) relies on the widely stablished biomechanical principles of retention, stability and support. In contemporary approaches, however, open prosthetic designs with minimal oral tissues coverage have been advocated. Longstanding conflicting opinions regarding the indirect retention concept have arisen, although robust scientific evidence is sti...

Use of distal implants to support and increase retention of a removable partial denture: a case report.

Lack of adequate support (tooth/soft tissue) results in displacement of bilateral and unilateral distal extension removable partial dentures. Placement of implants is one option for managing this problem. The aim of this report is to describe fabrication of a mandibular removable partial denture supported by 2 unilateral distal implants with locater attachments. The patient was a 70-year-old ma...

Occlusion and Temporomandibular Function among Subjects with Mandibular Distal Extension Removable Partial Dentures

Objective. To quantify effects on occlusion and temporomandibular function of mandibular distal extension removable partial dentures in shortened dental arches. Methods. Subjects wearing mandibular extension removable partial dentures (n = 25) were compared with subjects with shortened dental arches without extension (n = 74) and with subjects who had worn a mandibular extension removable parti...
