A process for the manufacture of several dental restorations, - wherein, based on a scanning result of an oral state, using a CAD software, a dental restauration is designed and produced in a residue-free removable material such as wax or polyacrylic, in a shaping step, as a positive model by ablation or generatively, for example by rapid prototyping, - which positive model is molded and removed via a muffle in a manner known per se, and which muffle is provided with a pressing channel which is connected via a feeder channel to a cavity corresponding to the positive model for the dental restoration, wherein the blank introduced into the pressing channel is heated and pressurized so that it will deform and dental material for forming the dental restorations enters and fills the cavity through the feeder channels, wherein - during the molding step or subsequently thereto, based on the dimensions of the muffle in relation to the size and shape of the positive model or positive models, at least one of the feeder channels is automatically created by a module of the CAD software for each positive model, - wherein the module defines a virtual interior space within the muffle for the arrangement of the dental restorations therein, - wherein the feeder channels are connected to the pressing channel such that they form a tree-like arrangement in which the pressing channel forms the trunk of the tree and the feeder channels form the branches at the top of which branches one of the dental restorations is provided, the respective feeder channel extending at an angle between more than 0° and 130°, in relation to the axis of the pressing channel, extending obliquely away therefrom, essentially along an isotherm in the muffle, and wherein the flow resistance of a ceramic material used as a dental material is set by dimensioning the respective feeder channel, - wherein the site having the thickest wall thickness of the positive model is selected as a docking site of the respective feeder channel on the corresponding dental restoration, and the module aligns the positive model with respect to the respective feeder channel such that it extends in extension of the axis of the respective feeder channel, - and the length of a virtual axis through the respective positive model is maximized. - wherein, based on a scanning result of an oral state, using a CAD software, a dental restauration is designed and produced in a residue-free removable material such as wax or polyacrylic, in a shaping step, as a positive model by ablation or generatively, for example by rapid prototyping, - which positive model is molded and removed via a muffle in a manner known per se, and which muffle is provided with a pressing channel which is connected via a feeder channel to a cavity corresponding to the positive model for the dental restoration, - during the molding step or subsequently thereto, based on the dimensions of the muffle in relation to the size and shape of the positive model or positive models, at least one of the feeder channels is automatically created by a module of the CAD software for each positive model, - wherein the module defines a virtual interior space within the muffle for the arrangement of the dental restorations therein, - wherein the feeder channels are connected to the pressing channel such that they form a tree-like arrangement in which the pressing channel forms the trunk of the tree and the feeder channels form the branches at the top of which branches one of the dental restorations is provided, the respective feeder channel extending at an angle between more than 0° and 130°, in relation to the axis of the pressing channel, extending obliquely away therefrom, essentially along an isotherm in the muffle, and wherein the flow resistance of a ceramic material used as a dental material is set by dimensioning the respective feeder channel, - wherein the site having the thickest wall thickness of the positive model is selected as a docking site of the respective feeder channel on the corresponding dental restoration, and the module aligns the positive model with respect to the respective feeder channel such that it extends in extension of the axis of the respective feeder channel, - and the length of a virtual axis through the respective positive model is maximized.
