Selection Of Restorative Materials "How To Live A Healthier Life With Durable Restorative Materials" A brittle material is highly susceptible to surface flaws and internal defects when tensile stresses are present. Because it cannot plastically deform to reduce stress concentrations and its tensile strength is far lower than its compressive strengths. The … [Read more...] about Selection of Restorative Materials: Understanding Strength, Stress

Casting Investments and Casting Procedures
Casting Investments And Casting Procedures Following are the different types of expansions to compensate for the casting shrinkage: Normal Setting Expansion: As the water gets mixed with investment powder, water surrounds the calcium sulfate crystals and converts them into calcium α-dihydrate. Setting expansion enlarges the mold partially for casting shrinkage of gold … [Read more...] about Casting Investments and Casting Procedures
Effective Binders in Investment Casting: Types, Uses, and Casting Procedures
Effective Binder In Investment Casting A material that will set and bind together the particles of a refractory substance known as a “binder”. In gypsum-bonded investment: Dental stone (alpha hemihydrate) acts as a binder for investment used in casting gold-containing alloys. Gypsum-bonded investment permits the pouring of the mix into the mold. Gypsum-bonded … [Read more...] about Effective Binders in Investment Casting: Types, Uses, and Casting Procedures
