264 16, 4332021

Abstract:

A method for making a denture comprising a base and a plurality of teeth joined thereto. The method comprises forming a first cavity in a block of a denture base material, the first cavity being formed to match the contour of natural teeth as arranged on maxillae or on a mandible; filling the first cavity with a first fluid synthetic tooth material and solidifying the first fluid synthetic tooth material into a first solid synthetic tooth material; removing a portion of the first solid synthetic tooth material to form the plurality of teeth; and removing a portion of the block of denture base material to form the denture base. The steps of the method may be implemented by a computer. An apparatus for making the denture according to certain embodiments of the method, and a denture comprised of a base and artificial teeth are also disclosed.

Abstract:

A method of making a denture comprised of fabricating a mold form, including a mold surface corresponding to an external surface of the denture; casting a liquid mold block material against the mold surface of the mold form, and curing the liquid mold block material to form a solid mold block including a second mold surface corresponding to the external surface of the denture. Denture teeth are placed in the tooth sockets of the mold block. Denture base material is delivered against the denture base surface portion of the second mold surface and bases of the denture teeth. The liquid denture base material is cured into a solid state to form a denture base block including embedded denture teeth. The denture base block is placed in a milling fixture; and milled to form the internal surface of the denture.

A61C 13/01
A61C 13/08

Abstract:

A method of fabricating a denture, comprising milling a preliminary try-in denture from denture material comprising a layer of denture base material contiguous with a layer of denture tooth material. Denture base material is removed from the block to form a first part of the, labial, buccal, gingival, and flange regions of the denture base to form a preliminary denture. A preliminary mold is created from this preliminary denture. The preliminary denture is then further modified with deformable waxes in gingival and anterior tooth recesses to form a preliminary try-in denture, which is fitted to a patient and adjusted to optimal dimensions. The adjusted try-in denture is then reproduced by further molding methods, producing the final denture.

International Classification:

A61C 13/00
A61C 13/34

Abstract:

A method for making a denture comprising creating three-dimensional models of top denture base, bottom denture base, and denture tooth molds; fabricating the molds by an additive manufacturing process; joining the bottom denture base mold to the top denture base mold to form a denture base mold cavity; injecting fluid synthetic denture base material into the mold cavity and curing the material to form the denture base; removing the bottom denture base mold from the top denture base mold, while leaving the denture base in the top denture base mold; joining the denture tooth mold to the top denture base mold to form a mold cavity defining the shape of denture teeth; and injecting fluid synthetic denture tooth material into the denture teeth mold cavity and curing the material to form the denture teeth joined to the denture base. An apparatus for making the denture is also disclosed.

Abstract:

A device for making artificial teeth for a denture. The device is comprised of a nest comprised of a lower portion formed of a rigid material and having an upper planar surface, and an upper portion contiguous with the upper planar surface of the lower portion, and formed of an elastomeric material and configured to receive a plurality of the artificial teeth and hold the teeth in predetermined positions relative to the upper planar surface. A method for making artificial teeth using the nest and a fixative applied thereto is also disclosed. The method may include milling of the artificial teeth by a CAD-CAM operated mill.

Abstract:

A method and apparatus for making a denture base disc that is used subsequently to form a removable denture. A vessel with an elastomeric lining is used to form the denture base disc so that the compression of the elastomeric material is approximately equivalent to the shrinkage of the denture base disc material during its polymerization. The vessel and elastomeric lining contained therein work cooperatively to cause the denture base disc to cure in a homogenous manner with consistent pressure on all sides so that residual stresses in the finished disc are minimized.

Abstract:

Dental prostheses and methods for making them are disclosed. In one embodiment, a method comprises a sequence of steps including milling a cavity in a block of a coping material, filling the cavity with a green ceramic material, milling a portion of the green ceramic material away to leave a layer of green ceramic material on an occlusal surface formed in the coping material, milling the underside of the block of coping material to form the coping with green ceramic material, and sintering the coping with green ceramic material to complete the prosthesis. The milling steps may be performed by a computer-controlled mill. The computer may execute a CAD-CAM program that includes data from a three dimensional model of a tooth that is to receive the prosthesis. The dental prosthesis may be a dental crown or a dental bridge.
