A method for making a dental bridge that fits the wearer thereof to an optimal degree, comprising the steps of
- preparing an integrally-formed wax bridge having a generally U-shaped configuration and connectors,
- separating the wax bridge into a plurality of integrally-formed bridge segments by cutting the connectors at preselected abutments, thereby eliminating the communication of distortion-creating stress among said segments, attaching a meltable support bar means to each pontic and coping of said wax bridge,
- preparing for the interconnection of preselected, opposed first and second posterior abutments disposed at the free ends of said U-shaped wax bridge by disposing a substantially rigid, first meltable bracing bar means intermediate of said opposed posterior abutments and connecting one end of said first meltable bar means to a first one of said abutments,
- interconnecting preselected, adjacent anterior abutments disposed at the bight portion of said U-shaped wax bridge by a substantially rigid, second meltable bracing bar means to hold said adjacent abutments in fixed space relation to one another,
- preparing to interconnect said first and second meltable bar means to one another by disposing a third meltable bracing bar means intermediate said first and second meltable bracing bar means along the axis of symmetry of said U-shaped wax bridge, and connecting said third meltable bar means to said second meltable bar means,
- fixedly securing each of said meltable support bar means at spaced intervals along the length of a meltable, integrally-formed, rigid anchoring member having a generally U-shaped configuration and having a linear-in-configuration transverse bar member that interconnects the opposed free ends of said U-shaped anchoring member such that said wax bridge and said anchoring member are disposed in spaced, parallel relation to one another,
- connecting said plurality of bridge segments to re-establish said integrally-formed wax bridge,
- connecting said opposed first and second posterior abutments by attaching said first meltable bar means to the second one of said abutments, to hold said opposed abutments in fixed, spaced relation to one another,
- connecting said third meltable bar means to said first meltable bar means, to establish a rigid frame formed by said first, second and third meltable bar means to hold the pontics and copings of said wax bridge in fixed, spaced relation to one another, disposing a stabilizer bar means in generally upstanding relation intermediate of said first meltable bar means and said anchoring member's transverse bar member and connecting opposed ends of said stabilizer bar means to the respective medial portions of said first meltable bar means and said transverse bar member to establish a rigid frame defined by said integrally-formed anchoring means and the wax bridge that is held substantially immobile by said first, second and third meltable bar means,
- producing a metallic casting including a metallic bridge and metallic members from the connected anchoring member and wax bridge,
- separting the metallic bridge formed from the metallic members representing the meltable support bar members,
- applying porcelain to said metallic bridge by a baking technique, and
- separating the metallic members representing said first, second and third meltable bar means from the porcelain covered metallic bridge.
