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 ...

Holodent system: a new technique for measurement and storage of dental casts
SPIE Proceedings, 1990ABSTRACT A system for producing holograms and for three dimensional measurement of dental casts is described. Measurements were performed on a metal testpiece with sharp well-defined contours and on a dental cast. Measurement of the testpiece gave a precision of0.02 0.11 mm for x, y and z coordinates. Corresponding figures for the dental cast were 0.03

A technique for recording, printing, and mounting digital casts in centric relation is described. Combining elements of analog and digital workflows, centric relation records can be transferred by digital scanning and used to align casts for articulation.

This report describes a straightforward technique for verifying the accuracy of a definitive cast by using a maximal intercuspation record fabricated from polyvinyl siloxane occlusal registration material. This precise verification method detects inaccurate casts before the dental prosthesis is fabricated, thus saving chairside and laboratory time ...

The fit of certain dental casting alloys using different investing materials and techniques
The Journal of Prosthetic Dentistry, 1966Abstract 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 biologically oriented preparation technique (BOPT) uses a vertical tooth preparation and simultaneously a controlled rotary instrumentation of the gingival sulcus. The resulting blood clot is stabilized with the interim restoration. However, accurate transfer of the emergence profile of the interim crown to the definitive restoration is essential ...

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 effects of casting techniques on the mechanical properties of a dental cobalt-chromium alloy
Journal of Materials Science, 1974Tensile 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.

For the fabrication of a removable partial denture, the orientation of a definitive cast should be recorded and reproduced to indicate the most desirable path of placement and undercut areas. This article describes a straightforward and accurate method of recording and reproducing the cast orientation by using an implant impression coping and an ...

Passive fit of the prosthetic superstructure is important to avoid complications; however, evaluation of passive fit is not possible using conventional procedures. Thus, the aim of this study was to check and locate mechanical stress in bar restorations fabricated using two casting techniques.
