DENTAL MATERIAL
20190125632 · 2019-05-02 ·

The present invention provides a dental material containing nanofibers and a biocompatible resin. In one embodiment, this dental material is an implant material, prosthetic material, or denture material and has mechanical strength suited to the site of use in the body as well as exceptional dimensional stability and exceptional wear resistance. Because the compressive strength can be controlled, excessive burden on the teeth when occlusal force is applied is suppressed when the dental material is used in the oral cavity. In addition, secondary caries can be suppressed because the antimicrobial properties make plaque less likely to adhere to the teeth and make the teeth less likely to be affected by bacteria. This dental material can be used without modification as a desired dental material, and can also be made into a desired dental material by molding as needed. In addition, materials produced from these nanofibers and this resin can also be used in applications other than dental materials.

Dental prosthesis and method of its production utilizing standardized framework keys and matching premanufactured teeth

A system including a method and associated structures creates efficiencies in the manufacture of prosthetic tooth support frameworks. Pre-manufactured teeth with matching internal keys are used in the setup of a patient prototype. Each key includes a shaft, a cervical platform, a retention knob and preferably at least one channel for the expulsion of excess adhesive fluid. The cervical platforms are shaped to provide intimate contact with a base of their respective tooth. The same tooth/key pairs are then used to make a framework pattern from the setup positioning. The pattern can be cast or scanned for direct machining to produce the finished framework.

Dental bridges and superstructures, and methods for manufacturing thereof

The present disclosure provides a dental bridge intermediary structure comprising a superstructure (203) and a reference plate (200), with distance pins (202) connecting the two. A method for producing a dental bridge superstructure (203) is also provided.

Method for producing a dental prosthesis

The invention relates to a process for producing a dental prosthesis with the chronological steps: A) Inserting the prosthetic teeth into the prosthetic base and connecting them with it in such a way that after their insertion into the prosthetic base the prosthetic teeth have limited movability in the prosthetic base B) Changing the position and/or the orientation of at least one prosthetic tooth in the prosthetic base; C) Fixing the prosthetic teeth on the coronal side in a key, and securing the orientation and position of the prosthetic teeth to one another in the changed position and/or orientation; D) Separating the prosthetic teeth from the prosthetic base; F) Fastening the prosthetic teeth in the prosthetic base with a cement or an adhesive, the gaps between the surfaces of the prosthetic base that are provided for fixation of the prosthetic teeth and the prosthetic teeth being filled with the cement or the adhesive; and G) Allowing the cement or adhesive to harden, the prosthetic teeth being solidly connected with the prosthetic base, so that the orientation and position of the prosthetic teeth to one another and to the prosthetic base is fixed, and separating the key from the prosthetic teeth. The invention also relates to a dental prosthesis produced using such a process and a kit to carry out such a process.

METHOD FOR DESIGNING DENTURE, METHOD FOR PRODUCING DENTURE AND POSITIONING MEANS
20190105133 · 2019-04-11 · ·

A method for designing dentures according to which artificial teeth can be easily and accurately attached to a denture base, which is designed and shaped by CAD/CAM, when the artificial teeth are arranged on the denture base is provided. The method for designing a denture (10) on a computer based on data on an intraoral shape comprises: creating data on a shape of a denture base (20) based on the intraoral shape (S22); creating data on a position of an artificial tooth (30) to be arranged on the denture base (S23); and creating data on a shape of an occlusal guide (40) that is tabular and has a recess part corresponding to a shape of the arranged artificial tooth in an occlusal surface side (S24).

DENTURE FABRICATION
20190105134 · 2019-04-11 ·

A single denture model that includes both tooth and soft tissue portions (e.g., gums and palate) may be provided in a computer-aided design (CAD) or computer-aided manufacturing (CAM) modeling environment. By cutting back soft tissue surfaces of the virtual denture model within the modeling environment, cutback volumes are formed that provide space for the subsequent application of a soft tissue insert that mimics soft tissue. A denture base including these cutback volumes can be fabricated from the virtual denture model, e.g., by milling or three-dimensional printing, and soft tissue inserts (e.g., custom-fabricated or prefabricated inserts) can be assembled onto the denture base to form a complete denture.

Denture As Well As Method Of Producing A Denture

The invention relates to a denture, made of teeth, in particular prefabricated teeth, and of a denture base made of a gingival material, comprising cavities for teeth in which cavities for the teeth are mounted, in particular attached by bonding, characterized in that the denture base (12) is produced by a CAD/CAM process forming the cavities (20) for the teeth (14), and in that cervical areas (40a) of the teeth (14) extending through the basal surface (16, 18) of the denture base (12) are removed, in particular abraded or milled.

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.
