Movement of three removable partial denture clasp assemblies under occlusal loading.

This investigation indicates that the design of the clasp assembly affects the magnitude of movement of the abutment tooth adjacent to an extension base but generally does not affect the direction of movement. Some clasp assemblies (distal rest) moved more than other clasp assemblies (wrought wire or I-bar), and hence, the abutment tooth moved more. The design of the clasp assembly did not seem to affect the magnitude of movement in the apical direction.

Need and effective demand for prosthodontic treatment.

The unmet and met need for prosthodontic services in the United States have been estimated and projected to the year 2000. Based on need-for-treatment estimates within the U.S. population collected by oral examination in 1971 to 1974, some 214.7 million hours of unmet need were estimated. By the year 2000, the projected need is expected to increase to approximately 264.7 million hours (if edentulism is assumed to be zero) or to approximately 293.8 million hours (if prevalence of prosthodontic need is assumed to remain stable). A concomitant rise in effective demand is also expected from 44.7 million hours in 1976 to 1977 to approximately 62.2 million hours in the year 2000. Thus, despite an assumption of declining edentulism, the unmet need for prosthodontic services will remain high.

Treatment for acute craniomandibular dysfunction symptoms in edentulous patients with unserviceable or no existing complete dentures.

This article describes techniques to make unserviceable complete dentures rapidly serviceable and to facilitate using them in the diagnosis and treatment of acute craniomandibular dysfunction symptoms in edentulous patients. A technique is described to make complete dentures rapidly in the event that the complete dentures cannot be made serviceable or the patient has no complete dentures. This technique uses the TRIAD visible light-cure system. Once the complete dentures are made, they can be used alone or in conjunction with an occlusal splint for the diagnosis and treatment of acute craniomandibular dysfunction symptoms.

Restoration of fixed partial dentures with fractured porcelain veneers using an overcasting.

Fracture and loss of the porcelain veneer of a fixed partial denture is troublesome. Dentists have frequently used overcastings to avoid removal of the restoration. However, development of proximal resistance and retention form for the preparation creates a problem because reduction of the connector causes fracture. Nevertheless, a box-type occlusal cavity form in the central portion of the preparation will enhance the stability of the restoration without encroachment on the connectors. This design is more applicable to endodontically treated teeth.

A metal insert to replace a fractured segment of a mandibular complete denture.

When surgical reduction is not possible for edentulous patients with little space between the retromolar pad and the maxillary tuberosity, dentures are most often made quite thin and as such are prone to fracture. When fracture of the lower denture base occurs, the denture is rebased, incorporating a case metal insert in the region of the previous fracture. Following the impression procedure, a pattern is developed on the master cast of the area to be replaced in metal. A casting is made in silver-palladium alloy and incorporated in the final wax-up. The denture is then processed by joining the metal insert into the denture.

Splinting: a retrospective 17-year follow-up study.

A retrospective 17-year, longitudinal study monitoring 66 patients with fixed partial denture and removable partial denture restorations revealed that perceptive splinting was beneficial and enhanced the longevity of the restoration. The study discussed the advantages and disadvantages of splinting, the survival rate of splints and splinted teeth, and the importance of oral hygiene and a periodic maintenance program.

A method to remold worn acrylic resin posterior denture teeth and restore lost vertical dimension of occlusion.

A method is described for remolding and correctly restoring abraded posterior denture teeth. By adding a layer of paraffin wax for jaw registration, the dentist can repeat the registration procedure until the proper jaw relation is established. This wax occlusal record is used as a guide during the remolding, and is incrementally replaced by autopolymerizing resin.

The genesis and evolution of acrylic bone cement.

In 1957 John Chamley and I began to discuss the question of cement fixation of femoral prostheses. This was an independent development, because we had no knowledge of any other work in this area. Our conclusion was to grout in the prosthesis with a suitable cement. I selected a cold-curing acrylic denture repair material called Nu-Life as most appropriate. This material proved satisfactory in laboratory and clinical trials, and in 1958 Chamley undertook hip replacement using a cemented femoral prosthesis in six patients. This clinical success aroused great interest and some skepticism, because it was not always appreciated that Charnley and I had a substantial body of scientific data that justified this new approach to arthroplasty. Not surprisingly,the clinical aspects received most emphasis in the next decade. The scientific data were published mostly in the dental literature and were forgotten by the time cementation arthroplasty was generally accepted and so were rediscovered in subsequent years.

Simplified procedure for replacement of retentive clips in a bar-retained implant overdenture.

Replacing the retentive elements in a bar-retained overdenture can be a difficult and time-consuming procedure. This article describes an impression procedure that allows the matrices in a bar-retained implant overdenture to be replaced in the laboratory using a heat-cured rebase procedure. Long waxing screws are used, which allows the bar to be removed in the rebase impression and incorporated in a new master cast. After completion of the laboratory phase, the bar is screwed back onto the implant abutments and the denture, with new retentive matrices, is inserted.
