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.

Disclosed is a method of manufacturing a digital overdenture. The method includes a first operation of aligning and setting a plurality of pieces of implantation information of fixtures according to alveolar bone information in a planning image, a second operation of designing and manufacturing a surgical guide and a holder abutment mounting guide, a third operation of preparing a temporary denture corrected to form a temporary holder insertion portion having an inner surface part into which a holder device is inserted to be shape-matched therewith, in which the surgical guide is installed in the target arch to implant the fixtures and the fixing bar is fixed to the holder abutments moved to and coupled with top ends of the fixtures by the holder abutment mounting guide, and a fourth operation of manufacturing a digital overdenture including an artificial tooth portion and an artificial gum portion.

A dental prosthesis and a process for design and manufacturing, incorporating a dental implant framework and veneering overlay that will be designed and manufactured simultaneously and permanently fixated to one another.

The disclosure relates to a reconstruction prosthesis including a plurality of prosthesis units connected in series. Each of the prosthesis units includes a main part and a cushion structure. The main part has an abutment insertion opening and an accommodation space. The cushion structure is located in the accommodation space and movably located at the abutment insertion opening and defining an abutment mounting hole connected to the abutment insertion opening. The cushion structure is deformable with respect to the main part.

Disclosed is a digital overdenture holder device, which is configured to be fixed to a plurality of fixtures implanted into a target arch to detachably fasten a digital overdenture so as to connect a fixing bar to the plurality of fixtures to an oral cavity. The digital 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 andto 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 pressurized and fixed to an inside of the through insertion portion.

A fixed hybrid dental attachment assembly is provided. The fixed hybrid dental attachment assembly includes an abutment member, a male member, and a cap. The abutment member has an outer locating surface portion projecting downwardly from an upper end. The male member for attachment to the abutment member has an upper end for engagement within a cap in a recess in a dental appliance, and a continuous, unbroken skirt projecting from the upper end of the male member for engagement over the outer locating surface of the abutment member. The skirt may have a rounded, convex outer surface, and the male member may be constructed from a PEEK material.

Plug-(1,9,10) is a solid shape, fabricated by 3D printers from dental resin, designed in Cylindrical-(1), Conical-(9) and Double Cylindrical-(10) shapes with straight leveled top heads-(2) and with 3 inclined leveled top heads of 30 (3), 45 (4) and 60 (5) for (1,10) with in the center of the top head a shallow Sinkhole-(8) as guidance point and at 0.25 mm a Handling Pin-(6,7) for transport, with a narrow Neck-(7) at the bottom as breaking point after positioning. Plug (1,9,10) is used to close the holes, that are left open after screwing abutments, and prosthetic reconstructions on implants. These screw holes have to be closed. If material obstructs the screw head, it is impossible to unscrew when needed, as screwdrivers will not fit. Plugs are Fabricated precisely in the diameters of the internal walls of the holes, thus creating a friction and a vacuum when placed, and insuring a precise fit without other aids.

A scanning jig is capable of acquiring spatial positional relationships between a patient's face and an abutment. The scanning jig is configured to identify the spatial position of an implant including the abutment placed in the patient's mouth, and includes a base to be connected to the implant, a scan target with a scan area scannable by a 3D scanner, and a connecting portion for connecting the base and the scan target. The connecting portion is connected at one end to the base in a predetermined direction and at the other end to the scan target in the predetermined direction, and has a predetermined length such that the scan target is positioned outside the mouth when the base is connected to the implant.

The present invention provides a digital dental prosthesis manufacturing method including a first step in which a three-dimensional work image is acquired, the three-dimensional work image including surface information on an inner side of an oral cavity and a target dental arch in which fixtures are placed and occlusion information between the target dental arch and an opposing dental arch; a second step in which a temporary digital dental prosthesis is designed and manufactured; a third step in which the manufactured temporary digital dental prosthesis is installed on the target dental arch; and a fourth step in which a virtual coupling groove, which corresponds to surface information on the corrected coupling region, is set in an inner surface profile, which is set according to surface information on the corrected temporary shape-matching surface that is included in the corrected scan image, and a final digital dental prosthesis is designed and manufactured.
