ABSTRACT:
A method and prosthesis assembly for fabricating a dental bridge to abutment teeth upon which metal retaining members have been mounted comprising suspending a pontic having non rigid arm rests extending from opposite ends thereof between the occlusal surfaces of the metal retaining members, adjusting the position of the arm rests to establish a desired alignment between the pontic and the abutment teeth, spot welding each arm rest to the occlusal surface of each retaining member to form a welded joint and soldering the interproximal space between each retaining member and the pontic. To facilitate the spot welding operation a metal spacer is interposed between the arm rest and the retaining member.
