Abstract
A wax profile for making a tooth for a dental bridge, the tooth having a cast gold alloy skeleton and porcelain coating, the skeleton being cast in a negative mold made from the wax profile and having the same shape as the wax profile. The wax profile having a wax, tooth-shaped body. The body having aligned upper and lower cavities connected vertically with a median channel to provide said porcelain coating filling the spaces of the cavities and channel with increased strength responsive to compressive forces applied vertically of the tooth.
Claims9
A wax profile for use in making a dental bridge, the wax profile adapted to be a model for a negative mold into which a gold alloy is cast to result in a skeleton having the same shape as the wax profile, the skeleton thereafter being coated with porcelain to form a tooth that can be joined into a dental bridge, said wax profile comprising:
- a body formed of wax and having a shape in the form of a tooth that in horizontal cross-section presents at least one substantially round lobe, said body having at least one upper tubular cavity opening to the top thereof and at least one lower tubular cavity open to the bottom thereof, there being a median tubular channel vertically connecting together the upper and lower tubular cavities, so that said porcelain coating said skeleton is continuous vertically through said skeleton to provide the tooth with high strength response to compressive forces applied vertically to said tooth in said bridge.
