Abstract
The invention provides a method for the manufacture of a dental restoration including the steps of forming a model of refractory material of a tooth, and forming, by flame spraying directly on to said refractory model, a base layer of predetermined thickness of said restoration, said refractory model being cooled during the formation of said base layer.
