Digital correction factors and mounting with digital correction factors of real prefabricated prosthetic teeth
The invention relates to correction factors, in particular digital correction factors or printed correction factors, as translation (x,y,z) data and/or as data of the rotation of at least one real prefabricated prosthetic tooth up to a plurality of real prefabricated prosthetic teeth in a mounting for material-ablating processing of the prosthetic teeth, the correction factors preferably being assigned to the mounting as bar code or as quick-response code for use in a digitally controlled material-ablating process, the mounting having at least one fixed real prefabricated tooth. The invention also relates to the mounting with assigned digital correction factors as well as to a method for determining the digital correction factors of the at least one real prefabricated prosthetic tooth.
METHOD FOR MANUFACTURE OF A REMOVABLE DENTAL PROSTHESIS BY MOULDING WITH THE AID OF A MOULD FORMED BY ADDITIVE MANUFACTURE
Disclosed is a method for manufacture of a removable dental prosthesis by moulding, the method including: digital modelling of a prosthesis model; a step of producing a mould including a lower half-shell corresponding to a tooth part of the prosthesis and an upper half-shell corresponding to a gum part of the prosthesis, the two half-shells being able to be joined together by affixing one to the other, thereby forming an impression of the prosthesis, the step including digital modelling of a model of the mould, followed by additive manufacture of at least the lower half-shell, and a step of producing the prosthesis, the step including in succession at least one provision of at least one artificial tooth, positioning of the artificial tooth in a seat of the lower half-shell, assembling the mould and pouring a filler material into the mould. Also disclosed is a prosthesis obtained by this method.
Common Placement Support for Artificial Teeth
Disclosed is a method for manufacturing a denture including a denture base and at least two artificial teeth arranged in the denture base, wherein the method includes the steps of obtaining the denture base; manufacturing the at least two artificial teeth with a common placement support connected to the at least two artificial teeth for keeping the at least two artificial teeth in a desired relative arrangement, arranging the at least two artificial teeth on the denture base with the common placement support connected to the at least artificial teeth, attaching the at least two artificial teeth on the denture base, and removing the common placement support. This further ensures proper placement of the artificial teeth in the denture base of a denture.
DENTURE BITE RIM SYSTEM WITH REPLICA TEETH
A bite rim system includes a plurality of dental bite rims having a shape and size that is suitable for use in a human mouth. A plurality of anatomically correct replica teeth are provided that include various tooth characteristics of different shapes, thicknesses, sizes and colors. A series of replica teeth are removably pre-mounted onto one or more of the bite rims in an anatomically correct pattern. The system also includes one or more replica teeth strips having a front facing surface with the image of one or more teeth imprinted thereon, and a back facing surface that is coated with an adhesive material for mating with one of the dental bite rims.
SYSTEM AND METHOD FOR MANUFACTURING LAYERED DENTURES
A method of manufacturing a layered denture in which the enamel layer or the tooth layer is manufactured first and the denture base is manufactured last. The resulting denture may exhibit an enamel layer or a tooth layer with enhanced strength and/or resiliency. The resulting denture may have one or more of an integrated layer, balanced occlusion, and a root approximating structure.
METHOD FOR PRODUCING A PROSTHESIS OR PARTIAL PROSTHESIS
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).
METHOD FOR PRODUCING A PROSTHESIS OR PARTIAL PROSTHESIS
The invention relates to a method for producing a prosthesis or partial prosthesis based on digital data, using multiple teeth present in a dental arch (14) and a prosthesis base to be produced, characterized in that the prosthesis base is rough-milled by means of a milling tool, i.e. is milled in a first step, and in that the prosthesis base present as a semi-finished product, in particular in regions of the prosthesis base on which the teeth and the prosthesis base abut against each another and/or are to be bonded to each other, is partially milled, i.e. is milled in a second step, by means of an in particular different milling tool, thereby being brought to a target height which corresponds to the desired bonding gap between the prosthesis base and the tooth or dental arch (14).
System for preparing teeth for the placement of veneers
Dental instrumentation for use in guiding a cutting tool to remove tooth structure from a working tooth is prepared. A digital model of cutting guide shell structure for placement around a portion of the tooth to be treated is combined with preset tool movements to be made by the cutting tool by one or more processors to define final cutting guide data corresponding to final cutting guide structure for guiding the cutting tool. A digital model of a fixation instrument configuration for fixing the dental instrumentation to an adjacent tooth to the working tooth is combined with the final cutting guide data by one or more processors to define final instrument configuration data corresponding to a final instrument configuration for releasably fixing the dental instrumentation to the adjacent tooth and for guiding the cutting tool in the removal of the tooth structure from the tooth to be treated.
Method of manufacturing removable denture, removable denture, and removable denture manufacturing apparatus
Removable denture data of a removable denture is produced, and disk frame data of a disk frame in which the removable denture is accommodated is produced, thereby building the disk frame based on the disk frame data. Next, a resin disk in which artificial teeth are embedded is produced by arranging the artificial teeth in the disk frame and curing a base resin, and a denture base is milled by milling the resin disk based on the removable denture data, thereby manufacturing the removable denture in which a base side of the artificial teeth is embedded in the denture base. As a result, artificial teeth having an excellent aesthetics may be used, it is possible to firmly join the artificial teeth and the denture base to each other, and it is possible to manufacture a removable denture with a favorable restoration accuracy of the artificial teeth.
System and method for manufacturing layered dentures
A method of manufacturing a layered denture in which the enamel layer or the tooth layer is manufactured first and the denture base is manufactured last. The resulting denture may exhibit an enamel layer or a tooth layer with enhanced strength and/or resiliency. The resulting denture may have one or more of an integrated layer, balanced occlusion, and a root approximating structure.
