The invention relates to a method for configurating a split denture. A digital 3D model of the denture comprising a plurality of teeth is provided. The digital 3D model of the denture is split into a digital 3D model of a base part and a digital 3D model of a teeth part. The base part comprises a first artificial gingiva portion. Further, the base part is configured to support the teeth part. The teeth part comprises the plurality of teeth of the denture and a second gingiva portion. The teeth part is configured to be mounted on the base part. The digital 3D model of the split denture is provided for generating at least one of the base part and the teeth part.

Disclosed is a method of manufacturing a digital overdenture to improve manufacturing convenience and preciseness. The method of manufacturing the digital overdenture according to the present invention includes a series of operations such as generating a planning image, manufacturing auxiliary devices for manufacturing the overdenture such as a surgical guide, a flattening guide, an impression model, and the like, setting a holder device and correcting a temporary denture, obtaining a corrected-scanned image, and designing and manufacturing a digital overdenture.

Bone-secured dental arch veneers and methods for fabricating and utilizing the same. The dental arch veneers include a veneer assembly having one or more tooth veneers and a support structure configured to support the tooth veneer(s). The dental arch veneers also include a coupling structure configured to interconnect the veneer assembly to a bone mount that is anchored along a user's maxilla or mandible. The coupling structure also is configured to permit the veneer assembly to be selectively and repeatedly interconnected with and disconnected from the bone mount. The methods include determining a target region within the user's mouth, obtaining a representation of the target region, manipulating the representation to create a desired arrangement of the user's teeth within the target region, determining anchoring positions proximate the target region for anchoring the bone mount, and forming the dental arch veneer based on the anchoring positions and the desired arrangement.

A method of taking a scan of a patient's oral cavity may include providing an anatomical healing cap that can be received within a subgingival void of a given tooth position. The method may also include taking a first scan (e.g., an extraoral scan) of the anatomical healing cap before seating the anatomical healing cap into the subgingival void of the given tooth position, where the anatomical healing cap is coupled to an implant disposed adjacent the anatomical healing cap. Further, the method can involve taking a second scan (e.g., an intraoral scan) of the anatomical healing cap and surrounding surfaces, and then integrating the two scans into an overall oral cavity scan. Reference points from the first scan may be used to align the second scan with the first scan, integrating the two together.

The present application describes a method for designing and manufacturing a denture device for a patient. A method is described for designing a virtual denture and manufacturing a denture device from the virtual denture. An apparatus is prepared having a denture teeth set-up that corresponds to a pre-designed denture teeth design and a denture base that comprises patient specific information. The methods and apparatus described herein reduce the number of visits required to manufacture a denture device.

Casting jigs, methods, and kits that may be used in manufacture of anatomical healing caps. A casting jig may include a body having one or more wells within the body, each well being open at a proximal end thereof and having a negative shape corresponding to an anatomical healing cuff body of a given tooth position. The casting jig includes an opening through the bottom surface through which an elongate handle may be inserted, allowing a temporary abutment to be coupled into the distal end of the elongate handle, so that the abutment is disposed in the well, held in place by the handle, as it is used as a core about which the anatomical healing cuff body is formed. A crown forming jig for forming an inexpensive, chair-side prepared bis-acrylic temporary crown that may be easily and quickly installed over the anatomical healing cuff body is also disclosed.

A dental prosthetic positioning assembly comprises an occlusal assembly and a maxillary arch subassembly. The occlusal assembly includes a maxillary tray configured to be formed in a patient's maxillary alveolar ridge, wherein the maxillary tray comprises a occlusal rim component. The occlusal assembly further includes a carriage frame component composed of biocompatible magnetic metal material anchored to the maxillary tray. The maxillary arch subassembly comprises a plurality of prosthetic maxillary teeth components magnetically anchored to the occlusal rim component. The carriage frame component is moveable with respect to the maxillary tray. The prosthetic maxillary teeth components are individually moveable with respect to each other to achieve a desired dental positioning.

The present disclosure relates to dental, free-radically polymerizable compositions, and to the use thereof in stereolithography and/or 3D printing, in particular for the 3D printing of dental shaped components, such as dental models, trays, try-ins or dentures. The dental, free-radically polymerizable compositions feature a change in opacity during the polymerization.

A process for replicating soft tissue anatomy of a dental patient prior to preparing an implant-supported fixed prosthesis is disclosed. The process may include: securing an interim prosthesis intra-orally in the dental patient for a predetermined time, after implants of the dental patient are osseointegrated, to evaluate the interim prosthesis based on a plurality of parameters within the mouth of the dental patient; printing a three-dimensional printed-resin prototype having an intaglio surface based on the evaluated interim prosthesis; attaching the three-dimensional printed-resin prototype into the implants; and injecting a low viscosity elastomeric impression material between the intaglio surface of the three-dimensional printed-resin prototype and the soft tissue of the dental patient to obtain a soft tissue replica for preparing the implant-supported fixed prosthesis.

A method of fabricating a denture, comprising milling a preliminary try-in denture from denture material comprising a layer of denture base material contiguous with a layer of denture tooth material. Denture base material is removed from the block to form a first part of the, labial, buccal, gingival, and flange regions of the denture base to form a preliminary denture. A preliminary mold is created from this preliminary denture. The preliminary denture is then further modified with deformable waxes in gingival and anterior tooth recesses to form a preliminary try-in denture, which is fitted to a patient and adjusted to optimal dimensions. The adjusted try-in denture is then reproduced by further molding methods, producing the final denture.
