摘要： A method of molding artificial teeth in denture base material comprising forming a U-shaped cavity in a block of denture base material, forming socket cavities in the bottom of the U-shaped cavity, casting a fluid artificial tooth material into the cavities, and causing the fluid tooth material to solidify into solid artificial tooth material while applying pressure. Causing the solidification may include heating the fluid tooth material. The method may include casting a liquid elastomer into a bottom portion of the U-shaped cavity following forming that cavity and prior to the forming the socket cavities, curing the liquid elastomer into a solid elastomeric cushion, and removing the cushion from the U-shaped cavity. Subsequently, the cushion may be inserted into the U-shaped cavity and contacted with the fluid tooth material. A die may then be contacted with the cushion to apply pressure to it and the fluid tooth material during curing.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
