Dental Amalgam Properties Explain the physical properties of dental amalgam. Answer: ADA specification no. 1 for amalgam alloy lists three physical properties as a measure of the quality of amalgam, i.e. strength, dimensional change, creep, and flow. Strength: The compressive strength of dental amalgam is strong but it is weak in tension and shear. "What Are The … [Read more...] about Dental Amalgam Properties

Casting Gold Alloys Classify casting gold alloys. Describe the composition, role of each constituent metal, and uses of casting gold alloys. Answer: Pure gold is a soft and ductile metal, and so is not used for casting dental restorations and appliances. Alloying gold with other metals not only improves its physical and mechanical properties but also reduces … [Read more...] about Casting Gold Alloys in Dentistry: Classification, Composition, and Uses

Answer: Alloy: An alloy is defined as a metal containing two or more elements, at least one of which is metal and all of which are mutually soluble in a molten state. "Risk Factors For Failure With Dental Alloys" Uses of Alloy: Alloy is used for all metal and resin … [Read more...] about Dental Alloys: Composition & Types

Gold In Dentistry: Alloys, Uses And Performance Write briefly on the classification of casting gold alloys. Or Write a short note on the classification of casting gold alloys. Answer: Classification of Casting Gold Alloys: In 1932, the National Bureau of Standards surveyed and later by ADA specification no. 5 and the American National Standard Institute (ANSI) has … [Read more...] about Gold In Dentistry: Alloys, Uses And Performance

Base Metal Alloys Write briefly on base metal alloys. Or Write short notes on base metal alloys. Answer: Base metal refers to the metal elements that are chemically reactive to their environment. Base metal alloys are those which contain little or no noble metals. The first base metal alloys were cobalt-chromium alloys primarily used for removable partial denture … [Read more...] about Base Metal Alloys Used for Dental Restorations and Implants
