METHOD AND APPARATUS FOR DENTAL CROWN RESTORATIONS USING PREFABRICATED SLEEVE-CROWN PAIRS
A dental restoration device includes a sleeve having an exterior surface and an interior pocket that is at least partially filled with a dental cement, and a crown having an exterior surface and an interior surface that is mated to the exterior surface of the crown and bonded thereto by an adhesive disposed between the exterior surface of the sleeve and the interior surface of the crown.
Dental prosthesis blank
A dental prosthesis is provided, manufactured from a monobloc or multibloc prosthesis blank (10), which is composed of a gum-colored material (14) and a tooth-colored material (12), which materials (12, 14) are bonded to each other by bonding, polymerization and/or one-piece manufacture. The boundary surface (16) between the materials is wave-shaped comprising alternating grooves (22) and ribs (24) in the course of the dental arch, and radial in an oral-vestibular direction in the region of the anterior teeth (33) to be created. The boundary surface (16), at least in the region of the molars (26)—again as viewed in the oral vestibular direction—has parallel grooves (22) and ribs (24) forming troughs and crests of the waveform, or grooves (22) and ribs (24) such that they extend in deviation from parallel by at most 10 degrees, in particular at most 5 degrees, at least in the region of the molars (26).

Dental devices and systems and methods for making the same
Dental devices and systems and methods for making the same are provided. In at least one embodiment, a computer readable medium containing instructions for fabricating an arch-shaped device for coupling to a patient's mouth is provided. The instructions can include using a denture form device to obtain an impression of a patient's mouth. The instructions can also include selecting an arch device and adapting that arch device to conform to a model of a patient's mouth, such that the adapted arch device may be used to ultimately form a denture.
METHOD OF MANUFACTURING DENTAL PROSTHESES AND DENTAL PROSTHESES
The present invention describes a method for the manufacture of dental prostheses where traditional artisanal or purely manual techniques are combined or merged with other more recent ones based on digital design, which comprises obtaining a digital image of the patient's mouth, digitally designing the dental pieces (1) and the gum (4) in a personalized way for each patient, manufacturing both parts separately, mounting them by tonguing-and-grooving and finally treating the prosthesis. Furthermore, the present invention also includes a dental prosthesis that comprises at least one dental piece (1) and a gum, where both are bonded by tonguing-and-grooving means.
Method of, and system for smoothing teeth
A method of smoothing teeth by, for instance, filling in cracks, chips and eroded areas by applying calcium and/or casein and/or phosphate and a source of OH.sup.− ions thereto. The method optionally provides that very thin layer(s) of dental cement be interlaced with other applied materials, and that the results be maintained in contact with the teeth involved by application of a composition of matter that adheres to said teeth and holds the results in place, while allowing at least some permeation of saliva therethrough. The method can optionally involve application of a backing strip or tray or the like to secure the other materials in place, but this is not a requirement where the composition of matter is sufficiently securing.
Dental implant
Dental implant with a base body made of ceramic anchorable in a jawbone and an implant superstructure attachable to the base body using a screw, wherein in an assembled state of the dental implant, a threaded portion of the screw engages with an inner thread formed in a blind hole of the base body, wherein the implant superstructure is by the screw pressed against the base body and wherein the engagement between the threaded portion of the screw and the internal thread of the blind hole occurs only in a lower half of the base body facing away from the implant superstructure.
METHOD OF MAKING A DENTAL PROSTHESIS
The method is used for making a dental prosthesis or for the adaptation of an existing dental prosthesis for the inclusion in and attachment to existing residual dentition and/or at least one implant. Here, individual teeth and/or implants and/or the remains thereof form the anchor elements for anchoring the dental prosthesis. First, an imprint of the actual condition of the jaw of the patient occurs, from which a master model and a working model are molded. Then, the working model is adjustably fixed in a milling base and aligned with respect to the insertion direction in a milling machine or parallelometer. Next, adhesion surfaces (2) made from wax in the manner of wide-area brackets, an adhesive bridge or the like are molded onto the molded anchor elements (1). Then a molded connecting part (3) with a permanently attached parallelization pin (4) and/or retention anchor element is waxed thereon after successful alignment with the insertion direction by means of the parallelization pins (4). Subsequently either the teeth (7) forming the dental prosthesis, the cast-model framework (8) and further necessary parts are modeled in wax, or the already an existing dental prosthesis are modeled on. Finally the model is provided with injection molding passages (9), and for this purpose each of the elements is worked on individually. Then, the model is embedded and boiled out for removing the wax, and that finally after insertion of the interchangeable matrix (duplicating matrix) into the molded connecting part (3) and surface treatment of the mold inner surfaces and the plaster mold, the mold is removed, followed by the removal of the dental prosthesis.
METHOD FOR PRODUCING MOULDED PARTS, IN PARTICULAR DENTAL MOULDED PARTS
A method for producing molded parts from a sinterable mixing compound using a cold casting mold having a cavity that corresponds geometrically to the molded part and at least one opening into the cavity, wherein the mold is additively constructed from a starting material, in particular a 3D printing method using a 3D printer, and wherein the cavity is created on the basis of a digital data set, in particular based on a three-dimensional model of the oral cavity of a patient. The cavity is filled via the opening with the sinterable mixing compound, curing and/or solidifying the mixing compound, wherein gases and/or liquids contained in the mixing compound are discharged from the cavity via the opening, thermally and/or thermochemically decomposing the mold at a temperature from 200° C. to 2500° C. and sintering the mixing compound to hardness at a temperature from 900° C. to 2500° C. until a molded part is obtained.
