The invention provides a method for dental restoration including direct modification or customization of a final abutment inside the patient's mouth. The final abutment is made from a non-titanium material. The final abutment, after being completely modified or customized, may then be used to support a crown. The invention exhibits numerous merits such as simplified procedure, cost-effectiveness, reduction of laboratory adjustment, reduction of chair time, and reduction of dentist office visits.

A method of making a dental restoration has the step of providing a precursor of the dental restoration. The dental restoration has at least a first and a second surface portion which are delimited by a physical boundary structure. The method further has the steps of applying a first coloring solution associated with the first surface portion onto the first surface portion, sintering the dental restoration precursor, and removing the physical boundary structure.

The invention relates to a method for the preparation of a blank of a ceramic material, wherein a first ceramic material and then a second ceramic material of different compositions are filled into a die and wherein the materials are pressed and after pressing are sintered. A layer of the first ceramic material is thereby filled into the die and a first cavity formed in the layer, the second ceramic material is then filled into the first open cavity and the materials pressed together and then heat-treated.

Pre-sintered blanks based on lithium metasilicate glass ceramic are described which are suitable in particular for the preparation of dental restorations.

A dental implant unit includes a layer of synthetically created titanium dioxide. The dental implant unit has one end for connection and a lateral surface covering the implant unit except for the end for connection. The lateral surface includes a layer of synthetically created titanium dioxide while the end for connection is free from synthetically created titanium dioxide. Also, a method produces a whitened implantable dental unit. The method includes thermal oxidation of a dental implant unit that includes titanium.

A dental prosthesis is disclosed includes a prosthetic tooth element comprising ceramic and a veneer located on a surface of the prosthetic tooth element, the veneer comprising cured dental composite. The prosthetic tooth element can be fixed to a mount in a patient's mouth using the same dental composite used for the veneer. A method of forming a prosthetic tooth element is disclosed including filling a mould that is formed at least partially from flexible polymeric material with a dental mixture comprising ceramic, and applying pressure to the filled mould to form a prosthetic tooth element comprising ceramic with a roughened surface.

The present invention relates to a method of processing three-dimensional scan data for manufacture of dental prosthesis, the method identifies a position for an implant procedure on the basis of image data for an oral structure, and generates aligned image data by retrieving, from a library, data corresponding to a scan body or an abutment, only a part of which has been scanned, by replacing a part or the whole of the image data with the retrieved data, and by aligning a position and a direction of the image data. By using the method, user can easily identify an oral structure from the image data obtained by scanning partial shape of the scan body or the abutment, and the method provides feedback to the user so that the method guides the user to correct measurement. Therefore, the prosthesis can be manufactured more quickly due to reduced scan time.

A custom tool for forming a dental restoration in a mouth of a patient includes a first mold body providing for a customized fit with at least one tooth of the patient. The first mold body includes a portion corresponding with at least a first surface of the tooth and an interproximal portion corresponding with an interproximal surface of the tooth, the interproximal portion being of unitary construction. The first mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing a first portion of missing tooth structure of the tooth.

A method for generating a prosthesis or partial prosthesis based on digital data using a plurality of teeth (10) and a prosthesis base (12) to be manufactured, characterized in that the generatively or subtractively generated teeth (10) and/or the generatively or subtractively generated prosthesis base (12) are manufactured having oversize, apart from regions of the teeth (10) and the prosthesis base (12) on which the teeth (10) and the prosthesis base (12) abut against each another and/or are joined or connected to each other, and in that the teeth (10) and/or the prosthesis base (12) are subsequently brought to the desired original dimension, in particular milled, with at least partial removal of the oversize (30, 32).
