Laminated single impression technique for cast posts and cores

The Journal of Prosthetic Dentistry, 1985
A laminated single impression technique for cast post and core has been described. Its advantages are the ease and versatility with prefabricated or customized post techniques (Fig. 14) and the one-step registration of single or multiple divergent canals. Its disadvantage is the necessity for additional laboratory procedures.

All-Ceramic Post, Core, and Crown: Technique and Case Report

Journal of Esthetic and Restorative Dentistry, 2001
The functional and esthetic restoration of severely compromised anterior teeth is a challenge to clinicians in their daily practice. The duplication of the optical characteristics of an intact tooth, including shade, translucency, and fluorescence, is often made difficult by the use of metal infrastructures, such as post-and-cores and copings.

Direct pattern technique for posts and cores

The Journal of Prosthetic Dentistry, 1978
The technique described results in a well adapted cast post and core with good retention (Figs. 18 and 19). The chances of perforation of the root and trauma to the patient are reduced, and the expense of the procedure is minimal. This system is adaptable to single- or multirooted teeth and continually produces good results with minimal problems.

Evaluation of a two-piece post and core fabrication technique

The Journal of Prosthetic Dentistry, 1989
Casting a core to a prefit post reduces the need for adjustments at cementation. This study compared two-piece post and core castings to one-piece castings of the same geometric configuration. The specimens were made with 0.070-inch Whaledent laboratory burnout posts invested in a phosphate investment and cast with Midas, Sturdicast, or Rexillium III ...

Technique for post-core removal from a crown and a new post-core fabrication

The Journal of Prosthetic Dentistry, 1980
A method of removal of a post cemented to crown with the recovery of the undamaged crown has been presented. The fabrication of a replacement post-core assembly and the reuse of the original crown is described.

Simplified technique for refabrication of cast posts and cores

Journal of Prosthetic Dentistry, 2000
This article describes a simple procedure of recording contours of an existing cast post and core that needs to be reconstructed, using a polyvinyl siloxane material as a matrix for fabrication of a new cast post and core in a relatively short time with reduced cost.

Post‐and‐Core Assemblies Made With an Accelerated Pattern Elimination Technique

Journal of Prosthodontics, 1994
PurposeAccelerated pattern elimination has the potential for increasing productivity. This study evaluated the accelerated pattern elimination technique using three commonly used phosphate‐bonded investments.Materials and MethodsPart one of this study determined the mean time interval from start of mixing to the maximum exothermic setting reaction ...

A Comparison of an Accelerated Technique for Casting Post‐and‐Core Restorations With Conventional Techniques

Journal of Prosthodontics, 1993
Purpose This project compares an accelerated technique for the casting of post‐and‐core restorations with four traditional techniques. The accelerated technique uses two phosphate‐bonded investments and the traditional techniques use a gypsum‐ and a phosphate‐bonded investment.

Microhardness evaluation of a two-piece post and core technique

The Journal of Prosthetic Dentistry, 1993
This study compared the microhardness of one- and two-piece cast post cores. Twenty 0.070 inch Whaledent "burn-out" posts were invested in a phosphate investment, cast, and bench cooled to room temperature. Five samples, were grouped by Sturdicast or Midas metal and by casting technique.
