Various embodiments of improved methods of creating removable or fixed over-implant dentures are disclosed that make patients look younger without plastic surgery. Different combinations of dentures may be used. The Denture facelift System (DFS) improves the look of virtually some facial defects or aging wrinkles, improves appearance as called anti-aging. These methods provide state-of-the-art dentures while decreasing the number of clinic visits for the patient. The embodiments employ specialized impression trays, a facial and bite registration instrument, and teeth selection kit strips of films to increase the efficiency of the denture-making process. The facial registration instrument comprises adjustable rods and plates to secure a temporary measuring grid above the patient's face, allowing for more accurate marking of anatomical features on wax bite blocks.

Dental instruments, assemblies, and components for a dental instrument are described with a two-piece tip that includes a flexible tip end and a stiff shank. Various methods of assembly are described for securing the flexible tip end to the shank including utilizing a slot in the shank and one or more pins inserted through the tip and shank, a securing material, and forming the shank with a distal portion coupled to a portion of the flexible tip end.

A dental all-ceramic restoration and manufacturing method thereof; the outer surface of the dental all-ceramic restoration has neither visible marks remaining from the removal of the connecting bars (7) nor local grinding traces and chipping, and is smooth with uniform structure. The manufacturing method thereof is wet-forming or milling. No connecting bars are needed to connect the dental restoration bodies (3) with a surrounding mould blank or ceramic blank. This eliminates the need for manually cutting off the connecting bars (7) to separate the forming body from the surrounding ceramic blank, further grinding and polishing process to treat the excessively rough outer surface, and thereby reducing the risk of chipping and premature failure. In the manufacturing processes thereof, the hardened ceramic green body (2) made by wet-forming technique has more homogenous microstructure and less particle packing defects than the dry-pressed blanks and partially sintered blanks. Furthermore, higher surface smoothness can be obtained by milling unsintered hardened ceramic green body than by milling partially sintered blanks. The dental all-ceramic restoration has a high degree of surface finish, and can be directly used without polishing, veneering or glazing.

Custom dental prosthesis or implants each individually designed and manufactured to replace nonfunctional natural teeth positioned in a jawbone of a specific pre-identified patient are provided. An example dental prosthesis/implant includes a dental implant body having a prosthesis interface formed therein to receive an occlusal-facing dental prosthesis component. The prosthesis interface has a custom three-dimensional surface shape positioned and formed to create a form locking fit with respect to the occlusal-facing dental prosthesis component when positioned thereon.

Disclosed are a ball-type attachment device for an overdenture and and a method of producing overdenture to which ball-type attachments are applied. The ball-type attachment device for overdentures according to the present invention relates to an attachment device for implant-supporting overdenture, which includes an abutment configured such that a ball-shaped coupling protrusion is formed at the exposed distal end thereof, and a retainer configured to be separably fitted over the coupling protrusion by a fitting method. The retainer includes: a cushion part made of an elastically deformable material, and configured such that a coupling recession having a shape corresponding to the ball shape of the coupling protrusion is formed so as to allow the coupling protrusion to be separably inserted and fitted into the cushion part; and a fastening part configured to be fastened to the overdenture, and configured such that an accommodation recession configured to accommodate the cushion part is formed so as to allow the cushion part to be inserted and fitted into the fastening part.

A dental restoration model including a positive model (15) of a dental restoration piece. The positive model (15) defines at least the outer contour (36) of a dental restoration piece to be made using lost wax technology and is provided with a locating pin region which is defined especially according to a given optimization process. The locating pin region is provided with a guiding element (30) which accommodates and/or guides a material feeder (22, 24, 26 and 28).

A device is provided for resin pressing and finalization of removable dental prostheses. The device has a single body which is substantially shaped like a tray and reproduces an entire impression of a prosthesis. The device includes a plurality of artificial teeth embedded in a prosthetic body.

A customized dental device for placement over the natural teeth of a user is disclosed, as well as various methods for forming such a device. The method expands on conventional methods of forming a cast replica and model integrating retaining features into either the cast replica or a temporary model to help the device naturally and seamlessly hold to the teeth of the user in a customized manner. Alternative methods of formation through injection molding are disclosed. In different embodiments, the device may be used as a veneer to improve appearance of the user's natural teeth and/or as a weight control device by governing food intake.

A method and apparatus for the design and manufacture of dentures wherein the number of office visits that a patient must attend in order to develop and obtain dentures is reduced. In one embodiment, during a first visit, final impressions and a measurement of the patient's upper lip is obtained. In one embodiment, a lab then creates a denture base and applies tooth replicas. In one embodiment, this is done using a physical fabrication aid of an embodiment of the present invention. Alternatively, the denture base can be created from a digital representation, and the denture base is then preferably sized and adjusted during the patient's second visit before final dentures are created and provided to the patient during the patient's third visit.

Custom dental prosthesis or implants each individually designed and manufactured to replace nonfunctional natural teeth positioned in a jawbone of a specific pre-identified patient are provided. An example dental prosthesis/implant includes a dental implant body having a prosthesis interface formed therein to receive an occlusally-facing dental prosthesis component. The prosthesis interface has a custom three-dimensional surface shape positioned and formed to create a form locking fit with respect to the occlusally-facing dental prosthesis component when positioned thereon.
