![]() In general, multiple-phase alloys release more atoms than single-phase alloys. The elemental release from noble alloys is not proportional to alloy composition, but rather is influenced by the numbers and types of phases in the alloy microstructure and the composition of the phases. However, in general, several principles apply to alloy biocompatibility. Unfortunately, there is currently no way of completely assessing the biocompatibility of noble alloys (or any other material), because the effects of elemental release on tissues are not completely understood. Similarly, equivalent amounts (in moles) of zinc, copper, or silver will have quite different biological effects, because each of the elements is unique in its interactions with tissues. For example, the short-term (more than 1 to 2 days) release of zinc may not be significant biologically, but longer-term (more than 2 to 3 years) release might have more significant effects. The biological response is also influenced significantly by exactly which elements are released, their concentrations, and duration of exposure to oral tissues. Thus any toxic, allergic, or other adverse biological response is primarily influenced by elements released from these alloys into the oral cavity. The biocompatibility of noble dental alloys is primarily related to elemental release from these alloys (i.e., their corrosion). A detailed discussion about the principles of biocompatibility can be found in Chapter 6, but a few general principles are mentioned here. The biocompatibility of noble dental alloys is equally important as other physical or chemical properties.

The certificate may then be attached to the patient record. ![]() will include an IDENTALLOY® CERTIFICATE certifying the dental casting alloy we used to fabricate the prosthesis. ![]() With each case, Distinctive Dental Studio, Ltd. a traditional PFM crown please see the Alloy Material Specifications below for composition. Because the understructure composition varies slightly from a SLM PFM crown vs. SLM offers better fit as well as improved consistency and accuracy over traditional PFM crowns however, on occasion due to quick-turnaround time constraints, casting is necessary. SLM is an additive manufacturing process that uses 3D CAD data as a digital information source as well as energy in the form of a high-power laser beam thereby, creating three-dimensional metal parts by fusing fine metal powders together. ![]() primarily uses Selective Laser Melting (SLM) for our understructures.
