| 2 | Method of fabrication of translucent dental restorations without opacious substructures | US64766 | 1998-04-23 | US6033222A | 2000-03-07 | George J. Schneider, II; Lawrence Taub |
| A series of die spacers of differing shades are used to match or replicate an assortment of tooth stump or dentin tooth shades. Such die spacers correspond to shades of various manufacturers. This allows the dentist to approximate the proper shade of the tooth preparation in his prescription of a translucent restoration which is communicated to the technician. The technician then applies onto the die of the tooth preparation a die spacer closely matching the chosen tooth stump shade, allowing the technician to wax-up over the die with the selected die spacer. The die spacer retains the traditional function of creating the necessary space under the wax pattern or wax-up. After removal of the wax-up from the die, it is processed, following the manufacturer's procedures, to make a non-opacious substructure of, for example, a translucent ceramic restoration. The dental lab technician readily is then able to return to the patient's original tooth color preparation to complete the fabrication of the translucent restoration (bridge, crown, onlay, inlay or veneer) in accordance with the dentist's prescription. | ||||||
| 3 | Dental restoration holder system | US370187 | 1995-01-09 | US5669771A | 1997-09-23 | Robert L. Lee |
| A small, thin, flat, stiff tab is glued with a hot melt adhesive to the exterior surface of a dental restoration. For veneers, a primer is applied to the veneer before the adhesive to enhance the bond. The tab can then be gripped between a thumb and forefinger while placing the restoration on a tooth to which it is to be laminated. After the restoration is placed on the tooth with permanent bonding material between the restoration and the tooth, the tab is used as a vibrating transmitter to the restoration. The tab is vibrated by positioning a flat-sided dental shaft against the tab or an extension element and rotating the shaft with a dental handpiece. A group of tabs are conveniently supported in slots formed in the upper surface of a support. The slots are dimensioned in relation to the tabs in a manner such that one end of a tab is in a slot while the finger gripping area of the tab extends upwardly, away from the support for convenient gripping by a person's fingers. After the tab is attached to a restoration, it may be inserted and returned to a slot in a holder. | ||||||
| 4 | Method of making artificial tooth veneer | US303001 | 1994-09-09 | US5565152A | 1996-10-15 | Agneta E. Od en; Matts K. G. Andersson |
| A method of manufacturing artificial tooth veneer restorations for natural teeth composed of a ceramic core by pressing and sintering ceramic powder. The core is preferably manufactured from a high strength densely sintered ceramic material by copy milling from an impression of the prepared tooth surface to a compacted body, a presintered body or a sintered body. Alternatively, the core is manufactured by compacting the ceramic powder against a body, which surface is copy milled from a model of the prepared tooth surface. During the copy milling, the sintering shrinkage is considered by enlargement of that body. The tooth veneer restorations are given their final shape by shaping the external surface of the compacted, presintered or sintered ceramic body. After the final sintering, the external surface can be shaped before a veneer material is attached to the external surface of the core by firing of dental porcelain. Manufacturing ceramic teeth veneer restorations according to the method of this invention increases their strength and accuracy to shape. | ||||||
| 5 | Process for making ceramic dental crowns | US76981 | 1993-06-15 | US5346397A | 1994-09-13 | Kenneth S. Braiman |
| A process for making artificial porcelain teeth or laboratory fabricated dental crowns includes casting or molding a plurality of tooth-shaped unfired shells from ceramic powder and a resin, acrylic, wax or starch in liquid form and molded and hardened into shapes of predetermined tooth contours. These dried powder like, thin and highly characterized outside shells of a general tooth shape are then merged into a full porcelain powder buildup of the tooth shape by using conventional porcelain powders mixed into a paste, conventionally, as a filling medium completing the buildup of tooth or crown form. This form is then placed into a furnace and heated to purge undesired resin, acrylic, wax or starch and other extraneous material, and then it is baked conventionally to further purge same and obtain an artificial tooth or crown in the most desirable form possible for the technician who then finalizes the contour by grinding and polishing or glazing same conventionally. The powder like dried shell may be used with a substructure or glass core or refractory die. The process preferably includes the provision of determining the proper color of porcelain powders to use to arrive at the final color of the tooth or crown even before firing and baking the shell and filling medium. | ||||||
| 6 | Method of manufacturing ceramic artifical tooth restorations | US79607 | 1993-06-22 | US5342201A | 1994-08-30 | Agneta Oden |
| There is disclosed a method of manufacturing artificial tooth restorations for natural teeth or implants comprising a ceramic densely sintered, high-strength individual core B with dental porcelain A by powder metallurgical manufacturing methods. The inner surface I of the core B, which will fit against one or more prepared tooth surfaces P or artificial abutments, is manufactured by forming a ceramic powder mixture against a surface of a body at which this mentioned surface is manufactured by registering the surfaces of the prepared teeth or artificial abutments and their mutual relationship with a three-dimensional optical or mechanical reading method directly in the mouth or on a model of, e.g., plaster, after which the registered surfaces are reproduced in an enlarged size, e.g., with a computer-controlled milling machine. The amount of enlargement is calculated from the shrinkage of the ceramic material during sintering to full density and considering the gap for cement. | ||||||

| A crown and/or a replacement tooth and a method of in situ production thereof by grinding and shaping a tooth to form a prepared tooth; filling a transparent shell tooth form with a light setting resin; disposing the filled shell tooth form onto the prepared tooth; illuminating the filled transparent shell tooth form to set the light setting resin and bond the resin to the shell tooth form; and shaping and polishing the set resin in situ to form a crown. A set of shell tooth forms is provided which are formed from a light setting resin chemically compatible with the resin used to fill the form in order that bonding occurs therebetween. This feature enables the products of a replacement tooth formed in situ without the necessity of shell tooth form removal as heretofore required. | ||||||
| 8 | Artificial onlay tooth crowns and inlays | US753102 | 1991-08-30 | US5217375A | 1993-06-08 | Agneta E. Oden; Knut M. G. Andersson |
| The present invention relates to artificial onlay tooth crowns or inlays composed of a prefabricated core designed for preparations for onlay tooth crowns or inlays in natural teeth. The core is preferably fabricated from a high strength densely sintered ceramic material by copy milling from a negative reproduction from the prepared cavity to a compacted body or a presintered ceramic material. During the copy milling, the sintering shrinkage is considered by enlargement of the copy milled compacted body or the presintered body corresponding to the sintering shrinkage. The onlay tooth crowns and inlays are given the final shape by shaping the surfaces outside the cavity of the compacted or the presintered body. After the final sintering, the external surface can be shaped and a veneer material attached to the external surface of the core by, e.g., firing of dental porcelain. The manufacture of onlay tooth crowns or an inlay according to the method of the invention decreases essentially the manufacturing time for onlay tooth crowns and inlays and at the same time the strength and the accuracy to shape increase. | ||||||

| 13 | Technique for positioning dental crowns and inlays | US633899 | 1996-04-17 | US5851114A | 1998-12-22 | Robert L. Lee |
| Special tools and materials are provided For the fitting and placement of artificial crowns and inlays in a patient's mouth. One version of the kit comprises test ribbons, ribbon gripping forceps, crown gripping forceps, a crown placement tool, an adhesive dispenser, expendable adhesive, an adhesive dispenser stand, an inlay/veneer placement tool, and a number of plastic or metal shims. The inlay placement tool is fitted with hot-melt adhesive on its tip for fixed attachment of an inlay or veneer for placement in the mouth. The crown placement tool is adhered with hot melt adhesive to the biting surface of a posterior crown to be used as a crown placing device. The ribbon forceps is used to grip a thin precut test ribbon and hold the ribbon in the patient's mouth vertically on either the front or back side of an artificial crown being placed. The crown placement tool is used to position an artificial crown in the patient's mouth onto the prepared tooth alongside the test-ribbon, whereby withdrawing the test ribbon with the ribbon forceps tests and marks the area of interproximal contact of the crown or inlay as well as the amount of pressure of the contact. The crown gripping forceps is also used to place an artificial crown for final cementation. The adhesive is not only used to place and remove an artificial crown or inlay for fitting, but is also used for the patient to bite on during cementation to keep the crown or inlay seated. Alternatively, the kit may be supplied with a number of ball posts and a ball post stand instead of the crown placement tool. In this version of the kit, the ball posts are adhered to the biting surface of the crown. The ball post may then be gripped with the crown gripping forceps. The forceps, while gripping the ball post, may be used to direct the crown into the mouth for marking, fitting, or cementing. | ||||||
