title: A method to improve passive fit of frameworks on implant-supported prostheses: an in vivo study.
abstract: OBJECTIVE
  A die stone jig was evaluated as to its ability to clinically verify the position of the abutment replicas on the master cast.
  
  
  METHODS
  A clinical evaluation was made on 58 edentulous arches necessitating rehabilitation with fixed partial dentures. Any broken jigs detected were replaced with a new set of jigs and clinically retested. Data were statistically confirmed.
  
  
  RESULTS
  Fifty-five percent of the 58 jigs broke, with a 95% confidence interval (CI) of 42.5 to 67.3; after replacement, there were no breakages (95% CI: 0 to 6.2).
  
  
  CONCLUSIONS
  The jig detected misfits in clinical trials, according to the parameters defined in the literature.
