Comparison of Dimensional Accuracy between Open-Tray and Closed-Tray Implant Impression Technique in 15° Angled Implants
STATEMENT OF PROBLEM Various impression techniques have different effects on the accuracy of final cast dimensions. Meanwhile; there are some controversies about the best technique. PURPOSE This study was performed to compare two kinds of implant impression methods (open tray and closed tray) on 15 degree angled implants. MATERIALS AND METHOD In this experimental study, a steel model with 8...
متن کاملEC DENTAL SCIENCE Case Report An Alternative Implant Impression Technique with Limited Interocclusal Space: Closed-Tray Impression Posts for Open-Tray Impression Technique
Accurate impression is a main requirement for obtaining passive fit of restorations. The aim of this case report is an alternative technique in using closed-tray impression posts for open-tray impression technique for exemplification at a patient that can have limited interocclusal vertical space. After osseointegration, 7 implants examined in edentulous maxilla, open-tray impression technique ...
متن کاملAccuracy Comparison of Implant Impression Techniques: A Systematic Review.
BACKGROUND Several studies link the seamless fit of implant-supported prosthesis with the accuracy of the dental impression technique obtained during acquisition. In addition, factors such as implant angulation and coping shape contribute to implant misfit. PURPOSE The aim of this study was to identify the most accurate impression technique and factors affecting the impression accuracy. MAT...
