Process for the production of parts of dental prosthesis digital data recording surface of an area of residual tooth, three-dimensional design of at least one piece of dental prostheses area residual tooth including data recorded area surface residual tooth and creating shape data corresponding, partial or complete production of the at least one piece of dental prostheses based on the surface data and the shape data, creating a component of the total molding from the melt geometric data of at least a predefined three-dimensional body shape data of at least part of the dental prosthesis designed three-dimensionally, in which three-dimensional bodies predefined are designed as intermediate members (17) or artificial teeth (12) of a dental bridge (13) and is extracted from a database and the fusion of different three-dimensional bodies is rounded and l step binding sites, wherein the roundness (14) are taken into account stability criteria and criteria anatomical shape according to the specifications of the forms of natural teeth, characterized in that as dimensional bodies predefined parts used a connection rod to connect two bridge elements, and that the directions of insertion necessary for building a rod connection can be established.Procedimiento para la producción de piezas de prótesis dental con registro digital de datos de la superficie de una zona de diente residual, diseño tridimensional de al menos una pieza de prótesis dental para la zona de diente residual incluyendo los datos de la superficie registrados de la zona de diente residual y creación de datos de forma correspondientes, producción parcial o completa de la al menos una pieza de prótesis dental basándose en los datos de la superficie y los datos de forma, creación de una pieza constructiva de moldeo total a partir de la fusión de datos geométricos de al menos un cuerpo tridimensional predefinido con datos de forma de al menos la pieza de prótesis dental diseñada tridimensionalmente, en el que lo
