Journal of Materials Science, 1975 A study was made of the effect of mould orientation on the mechanical properties of eight dental cobalt-chromium alloys prepared by centrifugal casting. In general, tensile test bars cast with their length horizontal rather than vertical to the induced gravitational field yielded superior elongation and ultimate tensile strength values.

The fit of certain dental casting alloys using different investing materials and techniques
The Journal of Prosthetic Dentistry, 1966 Abstract The relative fit of castings for normal tooth preparations and the Bureau of Standards MOD die were investigated. As used, the phosphate investments gave a degree of fit comparable with the thermal expansion gypsum types followed in order by ethyl silicate and hygroscopic materials.

The effects of casting techniques on the mechanical properties of a dental cobalt-chromium alloy
Journal of Materials Science, 1974 Tensile test pieces were cast by four selected sprueing techniques and studied for density and tensile properties. One of the sprueing systems referred to as horizontal twin feed produced the most consistent and the highest values for mechanical properties. This same series exhibited the lowest percentage elongation and the highest density.

A cast-free approach to fabricating an implant-supported interim restoration: A dental technique
The Journal of Prosthetic Dentistry, 2023A cast-free approach is described to fabricate an implant-supported interim restoration by using the postoperative cone beam computed tomography (CBCT) scan to locate the placed implant. A postoperative intraoral scan was aligned to the postoperative CBCT scan through a dental implant planning software program.

AbstractIntroductionThis study aimed to investigate the difference between senior dental students and prosthodontic faculty members regarding their opinions, attitudes and adoption of six split‐cast techniques for remounting complete dentures. The accuracy of each technique for measurements of the vertical and the anteroposterior dimensions was ...

To reduce the risk of implant and prosthetic complications, implant-supported prostheses should be passive. A verification device is used to verify the abutment analog position on the definitive cast, and hence its accuracy. This article describes the fabrication of a Type IV stone implant verification device for verifying the accuracy of the ...

Simple Technique to Reorient Different Casts of Same Patient on a Dental Surveyor
Journal of Prosthodontics, 2016AbstractAccurate planning for the framework design of removable partial dentures requires careful analysis of the diagnostic cast with a dental surveyor to determine the optimal path of placement. Some techniques described in the literature are helpful in reorienting the same cast on the surveyor, including the tripod marking method; however, there is ...

The holodent system, a new technique for measurement and storage of dental casts
American Journal of Orthodontics and Dentofacial Orthopedics, 1992A system for producing holograms and for three-dimensional measuring on holograms is described. The precision of the system was evaluated when three-dimensional measurements were made on (1) a holographic image superimposed on the corresponding object and (2) two superimposed holographic images of the same object.
