Summary

Objectives: Passive fit of screw retained frameworks is essential to avoid biological and mechanical failures in addition to transmission of unfavourable stresses to the bone-implant interface. However, Several factors contribute to the passive fit of screw retained prosthesis such as relative parallelism between the implants, implant number, impression material, impression technique and method of prothesis fabrication. The current study aims to evaluate the accuracy of three different impression techniques on the fit of screw retained bar splinting two inter-foraminal implants.

Methods: The study presents evaluation of the passive fit of screw retained bar fabricated with three different impression techniques.
