In order to improve the reliability of a dental restoration, a method of implanting the dental restoration is provided. The method includes virtually disposing a virtual implant selected from a digital library on the basis of a CT image to correspond to an implantation information, and a virtual implanting guide sleeve, which is virtually and concentrically disposed to be spaced upward from an upper end portion of the virtual implant by an offset distance, and a scanning image overlap and are integrally stored; and generating design information of a surgical guide, wherein a virtual coupling hole corresponding to an outer circumference of the virtual implanting guide sleeve is formed in the design information.

A method for making ceramic fixed partial dentures comprising separating the as-sintered partial denture structure, rejoining the retainers and pontic with glass, which forms a strong joint between the retainers and pontic after sintering. This method may produce ceramic long-span fixed partial dentures with a better fit.

The invention relates to a specimen part for creating a stress-free fit, a so-called passive fit, of implant-supported and/or abutment-supported bridges and bars by means of a CAD/CAM tool for the creation of restorations, and to a method for creating a restoration from a digital model of a patient's jaw provided with at least two implants and/or abutments. The model is determined by means of an intraoral scan. In order to improve the precision of restorations and to shorten the production process, provision is made that the specimen part per implant and/or abutment has a scannable structure, preferably at a defined distance and angle to the implant and/or abutment.

In order to improve the reliability of a dental restoration, the present invention provides a method of implanting the dental restoration. The method includes a first operation in which a three-dimensional planning image is generated in which a scanning image overlaps and matches to a computed tomography (CT) image, a plurality of pieces of implantation information of implants are set along a dental arch in the three-dimensional planning image, and an implanting guide device is designed and manufactured, a second operation in which an alveolar bone is flattened by being guided by the implanting guide device, the implants are implanted, and a holder device including a holder abutment and a fixing bar is fixed to an upper side of the implant, a third operation in which a temporary denture is corrected to be occluded between upper and lower jaws to form a temporary mounting portion in which the holder device is inserted into an inner surface portion thereof, a fourth operation in which a corrected scanning image corrected to expose three-dimensional exterior information of the temporary mounting portion to the outside is obtained from a scanning image of the temporary denture, and the three-dimensional exterior information of the temporary mounting portion is replaced and swapped with a virtual holder device, and a fifth operation in which a mount part is formed in an inner surface portion on the basis of the virtual holder device, and an artificial tooth part is fixed to an artificial gum part to which a clip engaged with the fixing bar is fixed so as to manufacture a final dental restoration.

The invention provides a dental prosthesis, comprising: an implant frame configured to be fixed into the mouth of a patient to support replacement of two or more teeth of the patient, the implant frame having an exterior surface, the exterior surface defining a first engagement profile; and an overlay adapted to be secured to the implant frame and to provide, or afford mounting of, the two or more teeth, the overlay having an internal cavity that extends along a substantial length of the overlay, the internal cavity defining a second engagement profile, wherein the second engagement profile is complementary to the first engagement profile, thereby allowing fitment of a substantial portion of the exterior surface of the implant frame within the internal cavity.

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.

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.

The overdenture holder device includes a holder abutment in which a through insertion portion is formed to be opened in both directions of a body portion having a bottom end portion inserted into a top end of the fixture and protruding upward and a fastening hole penetrates along a longitudinal direction and has an inner circumferential side on which a holding step protruding radially inward is formed, a fastening screw having a bottom end portion inserted into the fastening hole to be screw-coupled with the inside of the top end of the fixture and a head portion formed at a top end portion and to be held by the holding step, and a pressurizing device coupled with a top end of the body portion and configured to provide a pressurizing force such that an outer surface of the fixing bar is fixed to an inside of the through insertion portion.

A dental bridge includes a mounting structure and at least one pontic or artificial tooth mounted to the mounting structure. The mounting structure includes a first bonding pad, a second bonding pad spaced from the first bonding pad, a rigid wire having a first end fixed to the first bonding pad and a second end fixed to the second bonding pad, and the pontic is secured to the rigid wire, for example via a pontic attachment structure on the rigid wire between the first bonding pad and the second bonding pad.

The present invention relates to a missing tooth supplementing dental prosthesis that may provide the best wearing comfort regardless of the condition of a user's gums as the height of an end of a missing tooth supplementing member is adjusted according to the condition of the user's gums. The present disclosure proposes a missing tooth supplementing dental prosthesis including: a prosthetic body configured to be detachably worn in the oral cavity of a user who has at least one missing tooth, and provided with a fastening portion that is formed in a portion corresponding to a missing tooth; and a missing tooth supplementing member configured to be height-adjustably coupled to the fastening portion of the prosthetic body, to be height-adjusted according to the condition of the user's gums, and to supplement the missing tooth as an embodiment.
