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.
Claims20
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.
