Abstract

This invention is directed to a positioning jig for preparing a two or more of adjacent teeth for a dental prosthesis comprising a member with (i) three or more parallel bores in the member and (ii) one or more means to attach the member to a dental articulator. The invention is also directed to methods of use of the position jig such as to prepare a series of aligned holes in teeth or aligned holes mockup of a dental bridge for a prosthesis.

Claims

exact text as granted — not AI-modified
1 . A positioning jig for preparing two or more adjacent teeth for a dental prosthesis comprising: a member with (i) three or more parallel bores in the member; and (ii) one or more means for attaching the member to a dental articulator. 
     
     
         2 . The positioning jig of  claim 1 , wherein the member has four or more parallel bores. 
     
     
         3 . The positioning jig of  claim 1 , wherein the member has six or more parallel bores. 
     
     
         4 . The positioning jig of  claim 1 , wherein the parallel bores are perpendicular to the plane of the member. 
     
     
         5 . The positioning jig of  claim 3 , at least three of the parallel bores are of a first diameter and at least three of the parallel bores are of a second diameter. 
     
     
         6 . The positioning jig of  claim 1 , wherein the member has one means for attaching the member to the dental articulator. 
     
     
         7 . The positioning jig of  claim 1 , wherein the means for attaching the member to the dental articulator is a screw. 
     
     
         8 . The positioning jig of  claim 1 , wherein the means for attaching the member to the dental articulator is a pin and a screw. 
     
     
         9 . (canceled) 
     
     
         10 . The positioning jig of  claim 1 , wherein the member is a plastic frame. 
     
     
         11 . The positioning jig of  claim 10 , wherein the plastic frame is a clear plastic frame. 
     
     
         12 . A method of preparing an artificial prosthesis having two or more adjacent teeth which comprises:
 (a) preparing an artificial tooth arrangement (ATA) with two or more adjacent teeth in a mold on a positioning jig comprising a member with (i) three or more parallel bores in the member and (ii) one or more means for attaching the member to a dental articulator;   (b) placing at least three rigid struts in the parallel bores of the positioning jig;   (c) using at least one of the rigid struts to align a drill;   (d) drilling an aligned hole into each of the teeth in the mold;   (e) placing a rod in each of the aligned holes of the teeth to form a series of aligned rods;   (f) using the teeth and the aligned rods to prepare a dental mockup;   (g) copying the dental mockup to prepare a dental bridge; and   (h) affixing the teeth using the aligned holes to the dental bridge so as to prepare the artificial prosthesis.   
     
     
         13 . The method of  claim 12 , wherein the dental bridge is acrylic. 
     
     
         14 . The method of  claim 12 , wherein the dental bridge is metal. 
     
     
         15 . (canceled) 
     
     
         16 . (canceled) 
     
     
         17 . (canceled) 
     
     
         18 . (canceled) 
     
     
         19 . (canceled) 
     
     
         20 . (canceled) 
     
     
         21 . (canceled) 
     
     
         22 . The method of  claim 12 , wherein the artificial tooth arrangement (ATA) is prepared with three or more adjacent teeth. 
     
     
         23 . The method of  claim 22 , wherein the artificial tooth arrangement (ATA) is prepared with a full arch of adjacent teeth. 
     
     
         24 . (canceled) 
     
     
         25 . A kit which comprises:
 (a) a positioning jig for preparing two or more adjacent teeth for a dental prosthesis comprising a member with (i) three or more parallel bores in the member and (ii) one or more means for attaching the member to a dental articulator; and   (b) three or more rigid struts with a diameter so they fit tightly in the parallel bores.   
     
     
         26 . The kit of  claim 25 , wherein at least three of the parallel bores are of a first diameter and at least three of the parallel bores are of a second diameter; three or more rigid struts with a diameter so they fit tightly in the parallel bores of the first diameter; and three or more rigid struts having a diameter so they fit tightly in the parallel bores of the second diameter. 
     
     
         27 . The kit of  claim 25 , further comprising a set of shrink wrap tubes with a diameter suitable to fit on the rigid struts. 
     
     
         28 . The kit of  claim 25 , wherein the rigid struts are made of a ferrous material and further comprising a set of magnets capable of holding the rigid struts in the bores of the positioning jig. 
     
     
         29 . The kit of  claim 25 , further comprising a form for casting a mold to support an artificial tooth arrangement (ATA). 
     
     
         30 . The kit of  claim 25 , further comprising one or more drill bits suitable for drilling holes in artificial teeth.
