This study was conducted to evaluate objectively the relative distortion in three-unit bridges joined by laser welding, soldering, or one-piece casting techniques, Each procedure was replicated five times. Laser welding and one-piece castings of three units were found to be significantly superior to soldering. The laser welding was most reliable.
