The dentist begins by preparing the damaged or decayed tooth. Then an impression or digital scan is taken to capture the exact shape and dimensions of the prepared tooth and surrounding teeth.
The impression or scan is sent to Avant, where one of our expert technicians uses it to create a model of the patient’s teeth and a wax pattern of the full cast restoration with careful consideration given to the patient’s occlusion and aesthetics.
The wax pattern is then encased in a material called dental investment. This investment is placed in a special oven or furnace to burn out the wax. Molten metal – usually a metal alloy such as gold or a non-precious metal – is then poured into the mould through a process called casting.
After the metal has cooled and solidified, the investment material is carefully broken away to reveal the rough casting of the full cast crown, or the full cast inlay and onlay. The rough casting is then refined using various tools and techniques to achieve the desired fit, contour, and smoothness.
