Cyclic fatigue properties of cobalt-chromium alloy clasps for partial removable dental prostheses

Journal of Prosthetic Dentistry, 2010
Cast cobalt-chromium (Co-Cr) alloy clasps have been widely used for prosthodontic treatment, but long-term retentiveness of these clasps is not clear.The purpose of this study was to investigate the residual retentive force of 3 types of cast Co-Cr alloy clasps in relation to their proportional limits.Thirty half-round straight clasps and 30 ...

In vitro investigation of the performance of different restorative materials under cast circumferential clasps for removable dental prostheses

Clinical Oral Investigations, 2011
The objective of this in vitro study was to investigate the behavior of different composite restorative materials under the load of cast circumferential clasps for removable dental prostheses (RDPs).In 60 human molars, standardized mesial-occlusal-distal cavities were prepared.

Prognosis of double crown-retained removable dental prostheses compared with clasp-retained removable dental prostheses: A retrospective study

Journal of Prosthodontic Research, 2017
The present study compared the clinical prognosis of double crown-retained removable dental prostheses (D-DRPs) with that of clasp-retained removable dental prostheses (C-RDPs).Clinical records of 201 patients who had received 52 D-RDPs with 144 abutment teeth (D-teeth) and 199 C-RDPs with 399 abutment teeth (C-teeth) at the Prosthetic Dentistry Clinic

Analytical model of I-bar clasps for removable partial dentures.

Dental Materials, 2021
OBJECTIVE Clasps of removable partial dentures (RPDs) often suffer from fatigue stress that leads to plastic deformation, loss of retention, and RPD failure. Recently, computer-based technologies were proposed to optimize clasp geometry design.

A clinical investigation of the fit of removable partial dental prosthesis clasp assemblies

Journal of Prosthetic Dentistry, 2006
Removable partial denture frameworks are complex castings fabricated from high-shrinkage alloys. This may result in difficulty in achieving accurate fit.The purpose of this study was to evaluate which component(s) of the clasp assembly contact the abutment tooth clinically.New and existing frameworks with at least 1 conventional prepared occlusal rest ...
