A method of making a dental restoration, comprising the steps of: - providing a virtual three-dimensional model of the dental restoration; - defining a first boundary of a first surface portion associated with a desired first dental restoration color; - defining a second boundary of a second surface portion associated with a desired second dental restoration color; - along at least a portion of the first boundary and the second boundary in which the first boundary and the second boundary coincide, building up a virtual boundary structure; and - creating a three-dimensional model of the dental restoration precursor based on the dental restoration model and the virtual boundary structure; - enlarging the three-dimensional dental restoration model based on three factors which are based on the sintering shrinkage; - machining or building-up a dental restoration precursor based on the three-dimensionally enlarged dental restoration precursor; - wherein the dental restoration precursor of the dental restoration has an outer surface, the outer surface having at least a first and a second surface portion (11, 12) which are delimited by a physical boundary structure, wherein the first surface portion and the second surface portion are associated to the same vestibular surface of the dental restoration; - applying a first coloring solution associated with the first surface portion onto the first surface portion; - sintering the dental restoration precursor to form a preliminary dental restoration; and - removing the physical boundary structure to form the dental restoration. - providing a virtual three-dimensional model of the dental restoration; - defining a first boundary of a first surface portion associated with a desired first dental restoration color; - defining a second boundary of a second surface portion associated with a desired second dental restoration color; - along at least a portion of the first boundary and the second boundary in which the first boundary and the second boundary coincide, building up a virtual boundary structure; and - creating a three-dimensional model of the dental restoration precursor based on the dental restoration model and the virtual boundary structure; - enlarging the three-dimensional dental restoration model based on three factors which are based on the sintering shrinkage; - machining or building-up a dental restoration precursor based on the three-dimensionally enlarged dental restoration precursor; - wherein the dental restoration precursor of the dental restoration has an outer surface, the outer surface having at least a first and a second surface portion (11, 12) which are delimited by a physical boundary structure, wherein the first surface portion and the second surface portion are associated to the same vestibular surface of the dental restoration; - applying a first coloring solution associated with the first surface portion onto the first surface portion; - sintering the dental restoration precursor to form a preliminary dental restoration; and - removing the physical boundary structure to form the dental restoration. - enlarging the three-dimensional dental restoration model based on three factors which are based on the sintering shrinkage; - machining or building-up a dental restoration precursor based on the three-dimensionally enlarged dental restoration precursor; - wherein the dental restoration precursor of the dental restoration has an outer surface, the outer surface having at least a first and a second surface portion (11, 12) which are delimited by a physical boundary structure, wherein the first surface portion and the second surface portion are associated to the same vestibular surface of the dental restoration; - applying a first coloring solution associated with the first surface portion onto the first surface portion; - sintering the dental restoration precursor to form a preliminary dental restoration; and - removing the physical boundary structure to form the dental restoration.
