An improved dental casting investment

European Journal of Oral Sciences, 1980
Abstract –In the present investigation a gypsum‐bonded investment is presented with negligible setting expansion and a thermal expansion of 1. 7%. This investment can and should be used without a steel casting ring. In combination with an earlier described die‐spacing technique the new investment facilitates the production of gold inlays and crowns ...

Permeability and porosity of dental casting investments

The Journal of Prosthetic Dentistry, 1975
Permeability of various gypsum- and phosphate-bonded investments was measured during conventional burn-out procedures. Porosity determinations were made on specimens cooled to room temperature after burn-out. As a group, the gypsum-bonded investments were found to be more permeable than the phosphate-bonded investments. Two phosphate-bonded investments

The permeability of dental casting investments

Journal of Dentistry, 1974
Gas permeation through investment materials is important in obtaining sound castings by centrifugal or gas-pressure techniques. The equations governing permeation are presented, followed by measurements of the permeability to air of casting investments, comparing different types of material, powder : liquid ratios, and bake-out temperatures.

Modeling the surface contamination of dental titanium investment castings

Dental Materials, 2005
The objective of this study was to develop a computational tool for assisting the design of titanium dental castings with minimal defects and to compare computational simulations with casting experiments.Modeling. An in-house cellular-automata solidification and finite-difference diffusion program was coupled with a commercial casting program and ...

Multiscale modeling of titanium investment cast dental prostheses

Materials Science and Engineering: C, 2005
Titanium alloys are attractive materials for biomedical applications due to their superior biocompatibility. However, the use of titanium alloys for dental and maxillofacial prostheses is particularly challenging because each prosthesis has a unique, complex shape.

Setting expansion of gypsum-bonded investment in dental casting

Journal of Materials Science, 1989
The values of setting expansion of investment under uniaxial stress have been determined at conditions designed to obtain the difference of setting expansion between that parallel to the loading direction and that perpendicular to the loading ...

Thermal Behavior of the Gypsum Binder in Dental Casting Investments

Journal of Dental Research, 1986
This study examined the thermal behavior of cast gypsum specimens, with and without additives, by means of simultaneous differential thermal analysis-thermogravimetry (DTA-TG) and dilatometry. Specimens were prepared from wet-calcined hemihydrates (Hydrocal and Den-site).
