Why is the use of an ultrasonic condenser discouraged for the condensation of amalgam?
It increases the evaporation of the mercury, posing a health risk to the dental personnel.
Main components of amalgam?
Physical Properties of Amalgam. The most important physical properties of amalgam are flow and creep, dimensional change, and strength.(1) Flow and creep. Flow and creep are characteristics that deal with anamalgam undergoing deformation when stressed. The lower the creep value of anamalgam, the better the marginal integrity of the restoration. Alloys with high coppercontent usually have lower creep values than the conventional silver-tin alloys.(2) Dimensional change. An amalgam can expand or contract dependingupon its usage. Dimensional change can be minimized by proper usage of alloy andmercury.(3) Compression strength. Sufficient strength to resist fracture is animportant requiand the degree of porosity in the amalgam restoration.rement for any restorative material. At 50 percent mercury content, thecompression strength is approximately 52,000 pounds per square inch (psi). Incomparison, the compressive strength of dentin and enamel is 30,000 psi and 100,000psi, respectively. The strength of an amalgam is determined primarily by thecomposition of the alloy, the amount of residual mercury remaining after condensation,MD05021-6
