The Strengthening of Aluminous Porcelain with Bonded Platinum Foils

Abstract

Results are presented to demonstrate the effect of bonding thin platinum foils to aluminous dental porcelain. The increased strength is explained in terms of a reduction in surface and subsurface pores in the porcelain brought about by improved wetting.

A review of powder modifications in conventional glass-ionomer dental cements

“…It has been also demonstrated that the addition of either metal powders or fibers reduced abrasion resistance of conventional glass-ionomer cements, perhaps due to poor bonding between the reinforcing agent and the matrix. [62][63][64][65][66] 4.1. Stainless-steel glass-ionomer cements Kerby et al prepared stainless-steel glass-ionomer cements by combining atomized stainless-steel powder with an average particle size of 9 mm with a commercially available glass-ionomer powder.…”

The Three-point Beam Test for the Evaluation of Dental Porcelain

“…McLean and Sced4 proposed the use of tin-oxide-coated platinum foil as a reinforcing mechanism for porcelain jacket crowns. To confirm this, Sced et al 5 fabricated disc specimens for transverse testing. These were 1 5 mm in diameter and were tested on a circular knife edge support.…”

From Ceramics to Ceramic Steel: Genesis

“…It reduces surface and subsurface porosity in the porcelain and has the high strength of aluminous porcelain. 31,32 • Twin foil technique involves laying down of two platinum foils in close opposition to each other. One foil provides a matrix for the bonding of the porcelain which is removed after baking.…”
