A Method Aimed at Achieving Passive Fit in Implant Prostheses: Case Report

Purpose: The aim of this article is to describe a technique that attempts to solve titaniumrelated problems while affording passive fit. Materials and Methods: The method basically involves the manufacture of a cast titanium framework fitted onto titanium machined abutments. After verifying the passive fit of the framework presoldered to the abutments, Nd-YAG laser welding is completed in the laboratory. Results: The aim of the technique is to secure the following clinical benefits: (1) use of titanium, as it is the best-suited material; (2) use of high-precision machined abutments; (3) laser welding and its advantages; and (4) achievement of passive fit. Conclusion: The technique described is adequate to achieve passive fit in implant prostheses using titanium and laser welding.
