1. A method for producing partial dental prosthesis having at least one surface for forming a chewing surface of a posterior tooth, the method comprising:
(i) providing a composite material with at least one organic binding agent and solid particles that consist of glass as filler; and
(ii) applying a laser to at least some regions of a surface of the chewing surface in which the laser reaches a depth of 80 μm in the surface such that the at least one organic binding agent is burnt off in laser-treated regions and the solid particles are melted and fused together to form a continuous enamel layer.
