Abstract

A modified hygrosopic gold casting technique has been described. It utilizes a dual-wax pattern with controlled amounts of water added to the setting investment to better influence both the location and amount of investment expansion. This technique has been used since 1970 with excellent clinical results.

Flexible casts used in making indirect interim restorations.

This article describes a procedure for making indirect interim restorations from a cast and dies made of polyvinyl siloxane impression material. The use of these flexible casts and dies facilitates the removal of the polymerized resin from the cast and the rapid set of the polyvinyl materials reduces the time involved in making the indirect interim restorations.

Dimensional accuracy of small gold alloy castings. Part 4. The casting ring and ring liners.

The role of the casting ring and its asbestos liner is discussed. Asbestos as a liner has now largely been replaced by two alternative materials, one based on cellulose and the other on ceramic fibres. The limited literature on the effect of these newer materials on casting accuracy is also reviewed as their introduction may require significant changes in the traditional technology of dental casting.

Dimensional accuracy of small gold alloy castings. Part 1. A brief history and the behaviour of inlay waxes.

Part 1 reviews published studies which relate to materials and techniques contributing to the dimensional accuracy of small dental castings. A brief history of the cire perdue or lost-wax method of casting alloys and the development of modern dental casting materials and techniques are presented. Data on the behaviour of inlay wax, in particular its contraction and distortion, are reviewed as is the extensive literature about the casting shrinkage of gold alloys (Part 2) and the setting and thermal expansion of investments under both laboratory and practical conditions (Part 3). Part 4 discusses the role of the casting ring and its asbestos liner. Asbestos as a liner has now largely been replaced by two alternative materials, one based on cellulose and the other on ceramic fibres. The limited literature on the effect of these newer materials on casting accuracy is also reviewed, as their introduction may require significant changes in the traditional technology of dental casting.
