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.

A method for manufacturing and machining dental, maxillofacial and trauma prostheses and for optimizing an amount of time used in machining a prosthesis that has been previously manufactured with additive manufacturing technology is provided. The method includes manufacturing, by using excess material and additive manufacturing technology on a printing plate, a prosthetic block including at least a prosthesis. The method further includes joining pieces and positioning elements with specific dimensions and distances between the same; positioning the prosthetic block on a machining tray using the positioning elements; fixing the prosthetic block to the machining tray using the positioning elements; and fixing the machining tray to a machining machine, such that the prosthesis is fixed in a specific and known position in the machining machine by the specific dimensions and distances of the prosthetic block. The method further includes performing a machining operation to critical areas of the prosthesis.

A dental prothesis subsurface assembly including an O-ball joint distal from a neck, the neck having a smaller diameter than the O-ball and extending from an implant or an abutment, and a polymeric sleeve having a first inner diameter portion and a different second inner diameter portion the second inner diameter portion or the first inner diameter portion adapted to overlie the neck and the O-ball joint and having a portion of the O-ball joint extending into the other portion, the other portion adapted to receive a socket of a prothesis to prevent direct contact between the O-ball joint and the socket. Additionally, a process of joining a prosthesis to an implant including placing a polymeric sleeve over the O-ball joint and the neck of the implant and inserting a socket of the prosthesis over the sleeve joining the prosthesis and the implant without direct contact therebetween.

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.

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.

A multi-piece dental prosthesis system is provided. The system includes an implant which can be implanted into a bone of the patient, an abutment removably connected to the implant by a prosthetic screw, and a ti-base removably connected to the abutment. The system may be used to hold a crown, denture, or partial denture in place.

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.

Method for manufacturing a dental prosthesis on implant, characterized in that it comprises a step of manufacturing of the outer wall (E5) of the dental prosthesis and a step of manufacturing of at least one connection (E6) intended for fixing on to at least one implant.

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.
