PASSIVE ADAPTATION OF THE PROSTHESIS-IMPLANT INTERFACE BY SOLDERING GOLD CYLINDERS TO THE FRAMEWORK CASTING

Difficulties associated with accuracy of conventional long-span one-piece castings for fixed partial dentures are also observed in the fabrication of implant-supported prostheses. A technique is proposed whereby direct intraoral verification of cylinder-abutment relationship, master cast accuracy, possible corrected cast procedures, and soldering of gold cylinders to the framework ensure an accurate, passive adaptation of the prosthesis to all supporting implants.
