<br/><br/> Aim of the  study: this is an in vitro study To compare two types of impression techniques the primary splinted impression technique and the non splinted technique to evaluate which type produces a more passive metal framework for framework for fixed screw retained prosthesis . Conclusion: Under the limitations  of the present study, the splinted impression technique yielded statistically significant more  accurate working casts than the non-splinted technique especially for the lower arch
