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.

Disclosed is an apparatus for manufacturing a tooth model aids. The apparatus for manufacturing a tooth model, which is configured to dewax when molding a tooth model so as to manufacture a dental denture, may include an outer housing, an inner container installed in an inside of the outer housing, a flask unit installed in an inner space part of the inner container. The flask unit includes a mounting plate on which a flask is configured to be mounted, and a cover, the mounting plate of the flask unit includes a wax collection hole on a bottom of the mounting plate, and the cover includes a nozzle which is configured to selectively inject hot water or steam to the flask, the nozzle being formed at a location corresponding to a location of the flask.

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.

The invention relates to a dental restoration model comprising a positive model (15) of a dental restoration piece. Said 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 invention is characterized in that the locating pin region is provided with a guiding element (30) which accommodates and/or guides a material feeder (22, 24, 26 and 28).
