Provided is a reference denture alignment jig which guides reference dentures into an oral cavity or to an articulator in which upper and lower edentulous jaw models are fixed, and aligns the reference dentures in the oral cavity or in the articulator in which upper and lower edentulous jaw models are fixed, the jig having a reference denture holding portion for holding reference dentures.

A system and method of automated formation of a preparation stub, based on an a priori created computational geometrical model, configured to conform to a prefabricated fixed dental prosthesis, is described. The system includes a digital imaging facility with an image acquiring device and a three-dimensional data digitizer, a modeling facility with an exterior surface design module and an interior surface design module, a fabrication facility operatively with a computer-aided manufacturing module, as well as an application facility including an ablation tool and in-situ preparation module; application facility preferably includes an intra-oral feedbacking appliance with a distance measurement probe for automated feedback-controlled formation of a preparation stub.

A dental alignment guide system for dental implant placement has an anatomical guide, a tooth supported guide and a surgical guide. The system further can have an articulation piece, a prosthetic seat, an analog anatomical model and artificial teeth. The system has a plurality of implants, the implants being abutments, preferably multiunit abutments, a plurality of screws for attaching the anatomical guide to bone, pins to removably attach the various guides and the artificial teeth to the anatomical guide as assemblies during the method of practicing the invention.

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 tool for forming a dental restoration includes a mold body configured to provide a customized fit with at least one tooth of a patient. In some examples, the mold body defines an aperture configured to align with a portion of a surface of a tooth. The aperture is sufficiently large to allow placement and flow of restorative material over the desired portion of the surface of the tooth to be restored. The mold body is configured to combine with the at least one tooth of the patient to define a mold cavity encompassing at least a portion of desired tooth structure of the tooth to be restored.

The present invention relates to orthodontic positioning appliances that represent teeth in desired positions and related systems and methods. An appliance can include teeth receiving cavities shaped to receive and apply a resilient positioning force to a patient's teeth. An appliance can include an outer component having a surface representing teeth in desired positions. An outer component can be integral with an appliance. An outer component can be separate and configured to couple with an appliance main body.

A lower region of a temporary abutment includes an anti-rotational feature for non-rotationally mating with a dental implant. An upper region of the temporary abutment includes a first anti-rotational structure and at least one retention groove. A top surface of the temporary abutment includes one or more informational markers that provide information concerning the dental implant. A temporary abutment cap is configured to be coupled to the upper region of the temporary abutment. The temporary abutment cap has at least one projection configured to mate with the at least one retention groove of the temporary abutment. The temporary abutment cap has a second anti-rotational structure that is configured to slidably engage the first anti-rotational structure of the temporary abutment. The temporary abutment cap is configured to be coupled with a temporary prosthesis such that the temporary prosthesis and the temporary abutment cap are removable from the temporary abutment.

In order to improve manufacturing convenience and precision, the present invention provides a digital denture manufacturing method comprising: a first step of acquiring a three-dimensional work image, on which occlusion information between a target dental arch and an opposing dental arch and implant information of a fixture implanted in the target dental arch are displayed, and preparing a temporary denture in which a binding region formed to correspond to a binding portion profile of an abutment fastened to the fixture is arrayed and arranged; a second step of acquiring an auxiliary scan image for the temporary denture; a third step of acquiring, from the auxiliary scan image, a correction surface image on three-dimensional surface information of an inner surface-side engagement groove of the temporary denture including the binding region; and a fourth step of designing and manufacturing a digital denture having a virtual binding groove corresponding to the position and the shape of the three-dimensional surface information of the binding region, in an inner surface profile set according to the three-dimensional surface information of the engagement groove.
