| Abstract | ||
| Purpose: To evaluate the accuracy of two different impression techniques on the fit of screw retained bar in implant assisted overdentures. Methodology: Ten completely edentulous patients were selected from Removable Prosthodontics Department, AinShams university according to the inclusion and exclusion criteria. All patients received implant assisted mandibular overdenture with a screw retained bar. Two bars were made for each patient by two different impression techniques. In the first technique, open top impression was used to fabricate the screw-retained bar. However, in the second technique intraoral digital impression was used. Passive fit of each bar was then evaluated. Results: The results of this study showed non statistically significant difference between both impression techniques. Conclusion: Within the limitations of this study it may be concluded that the results for both impression techniques on the fit of the screw-retained bar in implant assisted overdentures Keywords: Intra oral scanning, Open top impression, Implant retained overdenture. | ||
