Abstract: Disclosed are pieces that are produced by sintering, which have well-differentiated surface finish areas including rough areas resulting from the sintering process, the roughness being determined by the size of grain used in sintering, and polished areas that have undergone a three-dimensional machining process. Also, dislosed is a method that, after obtaining a file containing a representation of the piece to be produced, comprises: selecting the parts to be raised; producing the piece by means of sintering; and subsequently subjecting the piece to automatic, semi-automatic or directed programming generation so that, by means of machining, the raised parts are reduced. Consequently, the resulting piece is economical in terms of costs and exhibits a very high degree of precision in the machined areas, a tolerance 9, and improved finish, texture and finishing in the sensitive areas of the piece.

Abstract: The system, object of the invention consists of a unit for scanning a mould produced from the sample from a patient's mouth, an image which is sent to digital generation equipment of a removable dental prosthesis, producing a file that is transmitted to metal piece manufacturing equipment by means of sintered powder applying a high-energy ray. The design stages consist of the relief of the mould, the calculation of the insertion axis, the paralleling of the teeth, designing of the elements or components of the prosthesis such as lattice, clamp, stop, major connector, minor connector, bristle, pearls, lingual bars, extrusion of the different elements designed, smoothing of the sharp edges, elimination of the superpositions of the different elements designed and conversion of a closed continuous connected surface to a three-dimensional one.
