Dental Casting Procedure

Dental Casting Techniques: An In-depth Look into the Lost Wax Method, aims to fill the void between theory and practice regarding dental casting materials science. The art of dental casting is arguably one of the most challenging skills in restorative dentistry. It distills information to its bare essentials by presenting the lost wax technique as an exact science that can be systematically applied. It traces the entire chronological development process from the biophysical aspects of tooth preparation and impressions to the stages of spruing, investing, burn-out processes, and divestment. Through the integration of basic principles discussed in Dental Materials and Pre-Clinical Prosthodontics, this work reveals the compensation mechanism, particularly how the setting, hygroscopic, and thermal expansion compensate for metal shrinkage. From preparing for academic exams to working at the laboratory bench, this guide serves as a scientific and rational basis for perfect marginal adaptation and ultimate strength in any restoration procedure.
