During sintering, fine-grained ceramic or metallic materials are heated up at a temperature below the melting temperature of the main components. The shape of the workpiece remains intact. The material condenses and shrinks. A green body is formed which solidifies by temperature. The sintered product only then gets its final properties such as hardness, strength or temperature conductivity. The sintering shrinkage is taken into account during the construction of the restoration – the workpiece is milled larger by the shrinkage factor.
