The qualitative assessment of cobalt-chromium castings for partial dentures
British Dental Journal, 1989Criteria for objective assessment of cobalt-chromium castings have been developed. A random sample of 21 commercial dental laboratories specialising in the production of cobalt-chromium castings was selected. Identical casts and instructions for the construction of a lower partial denture framework were sent to each of them. The resultant castings were

Casting titanium partial denture frameworks: A radiographic evaluation
The Journal of Prosthetic Dentistry, 2002Titanium is the most biocompatible metal available for dental castings. However, there is some concern about the castability of titanium used on a daily basis.A radiographic evaluation of titanium partial denture frameworks was undertaken to ascertain whether these castings were technically acceptable for clinical use.Three hundred Grade II titanium ...

Duplicate casts in fabrication of temporary removable partial dentures
The Journal of Prosthetic Dentistry, 1985The use of blocked-out duplicate casts in the fabrication of temporary removable partial dentures has been described. Temporary removable partial dentures produced in this controlled manner fit properly and aid in minimizing intraoral damage. Accuracy of fit is assured because all relief is accomplished by block out on the surveyor during the ...

Remount casts for removable partial dentures made in a laboratory
The Journal of Prosthetic Dentistry, 1989A remount cast for a removable partial denture can be made in the laboratory by making an elastomeric impression of the prosthesis on the cast after processing but before removing it from the cast. After the prosthesis is finished and polished it is placed in the impression, undercuts are blocked out, and a mounting cast is made.

Laboratory accuracy in casting removable partial denture frameworks
The Journal of Prosthetic Dentistry, 1985An attempt was made to compare the clinical accuracy of two types of cast metals used in the fabrication of removable partial dentures as they were prepared by commercial laboratories. No comparison of the metals could be made, because the discrepancies that were found were too gross and were related to technical error. Suprabulge clasps were placed in

Radiographic detection of porosities in removable partial denture castings
The Journal of Prosthetic Dentistry, 1985The purpose of this study was to discern the existence of structural defects in removable partial denture frameworks by means of radiographs. A simple technique was described using a dental radiograph unit and routine periapical dental films. All components of removable partial denture castings were radiographed with different angulations.

Removable cast partial dentures.
The New York state dental journal, 1995In planning treatment for partially edentulous patients, the dentist is often confronted with conditions that preclude fixed prosthodontics. In these instances the cast removable partial denture is often the alternative of choice. In planning and producing a removable partial denture that will be most satisfactory, a systematic evaluation at the very ...

Radiographic evaluation of porosities in removable partial denture castings
The Journal of Prosthetic Dentistry, 1978Most of the removable partial denture castings examined showed radiographic evidence of internal porosity. In general the porosity ocurred in characteristic regions associated with abrupt changes in cross-sectional thickness. These were located either within the partial denture framework or at the casting-sprue junctions.

A study of duplication variables related to partial denture castings
Australian Dental Journal, 1976Abstract— A series of stone duplications of a standard impression die was produced, using a proprietary duplicating material, the various batches of which had been prepared differently. Two different sized duplicating vessels were also employed. The critical dimensions of the stone reproductions were compared with those of the original die.
