EC 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 کاملInfluences of differences in tray design and impression material on impression pressure at edentulous mandible.
The aim of this study was to examine the effects of tray design and impression material on impression pressure in a clinical simulation model of an edentulous mandible. Two types of polyvinylsiloxane elastomer, one type of polyether elastomer, and one type of alginate were used. The three tray types had no relief, 0.36 mm of relief, or 1.4 mm of relief, with or without escape holes. Impression ...
