• I examined how fixation of the soldering investment and heat treatment after welding prevented welding deformation in a three-unit bridge. The experiment was carried out using a specially constructed metal die for welding that provided strong fixation. Deformations induced by soldering and one-piece casting were compared with these induced by laser welding. The best method of predictably obtaining precise dental prostheses was by welding the casting fixed firmly on the metal die and then heat treating it.
