When using CoCr alloys, a number of fractures occurred the Dental Laboratory, both when handling castings after they placed patient’s mouth. It is assumed that key cause resulting bridges casting process, which includes preparation mixing basic components alloy, unstable solidification fin...

Because osseointegrated implants have no resilience in bone, passive fit between dental implants and prosthetic superstructures has been identified, both from biologic and mechanical perspectives, as a potential discriminating prognostic factor. Distortion of the metal framework during the casting procedure has been cited as a main cause of misfit. The objectives of the present article were to ...
