Method of producing a dental product

摘要

Methods of producing a dental product are disclosed. Certain methods include the steps of providing a pre-sintered blank made from a green body of ceramic material, performing a machining operation on the blank, and subsequently sintering the blank to its final density in a sintering operation performed at a temperature in the range of 1300° C. to 1650° C. The pre-sintered blank that is provided may have a strength in the range of 53-107 MPa.

主权项

1. A method of producing a dental product, the method comprising the steps of:
providing a blank made from a green body of ceramic material, re-sintering at a temperature at a beginning of a neck area of a density versus temperature curve, wherein the neck area is where a relatively flat part of the curve is followed by a relatively sharply rising part of the curve, performing a machining operation on the blank, and subsequently sintering the blank to its final density in a sintering operation performed at a heating rate in the range of 0.1-1° C./minute and held at a temperature in the range of 1300° C. to 1650° C.
