Abstract: A method for assigning an order identification to a manufactured dental restoration, including the steps of scanning (S101) the manufactured restoration to generate an actual data set representing the actual shape of the manufactured restoration; retrieving (S102) a data set representing a nominal shape of a digital restoration and to which an order identification is assigned; comparing (S103) the actual shape with the nominal shape; and detecting (S104) the order identification of the data set when the actual shape corresponds to the nominal shape.

Abstract: The invention relates to a method of producing a dental prosthesis from a one-piece or multi-piece prosthesis blank which is constructed from a gum-colored material and a tooth-colored material (32), in particular in each case on a plastic base. It is characterized by being connected to each other at connecting surfaces, having an interface between the gum-colored and tooth-colored materials. This interface, when viewed along the connecting surfaces has an undulating shape and viewed in the vestibular direction has a radial shape. In order to finish the dental prosthesis, a CAD/CAM device determines the exact course of a gingival line, based on patient-specific data, and produces the prosthesis.

Abstract: A dental prosthesis is made by externally machining successive layers of wax, each of which is formed on a previous prosthesis layer and/or on a coping. Each wax layer is used to form a mold in situ over the previous prosthesis layer/coping, and the appropriate prosthesis material is cast or otherwise molded to conform to the wax layer by the mold.

Abstract: A system and method for post-processing of polymeric items having a liquid component and a predetermined heat deflection temperature is provided. The system includes a washing station to spray water at elevated temperature and pressure on the items while maintaining the temperature of the item below the heat deflection temperature. Then using a water distillation system to separate the water from the water mixed with the liquid polymer component by evaporating the water using heating coils with surface that is not conducive to adhesion of the liquid polymer component and then condense the water vapor into liquid water. The system may further include a spin station to separate the liquid polymer component by spinning the item. The system may further include one or more processing stations to rinse the item, dry the item, cure the item, remove the item from a tray to which the item may be attached and clean trays after removing the item.

Abstract: A method is provided for manufacturing a template, whereby a digital or physical model of the shape of at least a part of the jaw is generated. A desired shape for the jaw bone for positioning a bone superstructure is compared to the model and a bone part of the jaw bone is identified, which bone part is to be removed in order to approach the desired shape. A guide surface is provided on the template to guide a milling element in order to remove the identified bone part. A bone superstructure is also described.

Abstract: A method of forming an implant to be implanted into living bone is disclosed. The method comprises the act of roughening at least a portion of the implant surface to produce a microscale roughened surface. The method further comprises forming a nanoscale roughened surface on the microscale roughened surface. The method further comprises the act of depositing discrete nanoparticles on the nanoscale roughened surface though a one-step process of exposing the roughened surface to a solution including the nanoparticles. The nanoparticles comprise a material having a property that promotes osseointegration.

Abstract: A method for referencing a tracking system's coordinate frame to a rigid body's coordinate frame is disclosed. The method involves obtaining a 3D model depicting some of the surfaces of the rigid body. A probe is provided with an affixed tracking reference component. A second tracking reference component is attached to the rigid body. The method involves tracking locations of the probe as it moves along surfaces of the rigid body and then determining a transform that relates the probe locations to the 3D model of the rigid body. In one embodiment the rigid body is a dental mandible or maxilla of a patient and the 3D model is a surface extracted from a computed tomography image of the patient's jaw and teeth.

Abstract: A new titanium-based implant is disclosed, which is formed by a titanium coating manufactured with biomaterials with applications in osseous implantology. The nanotopographical characteristics of these implants inhibit bacterial adhesion and the formation of a bacterial biofilm on the surface, whilst simultaneously presenting suitable properties for the adhesion, stretching and proliferation of bone-forming cells. Moreover, the invention comprises a method for manufacturing the implant by means of oblique-incidence techniques and the use thereof in osseous implantology.
