title: A method aimed at achieving passive fit in implant prostheses: case report.
abstract: OBJECTIVE
  The aim of this article is to describe a technique that attempts to solve titanium-related problems while affording passive fit.
  
  
  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.
  
  
  CONCLUSIONS
  The technique described is adequate to achieve passive fit in implant prostheses using titanium and laser welding.
