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 should be used due to angulation and number of implants. Light-cured UDMA material is used for making personal tray. Closed-tray impression posts are inserted and impression is taken with polyether impression material. Impression posts are splinted to tray with light-cured UDMA. Tray is removed from mouth and a model is prepared. Metal-porcelain restorations are prepared conventionally. This case report shows a modified technique that mixes two impression types. This technique can lead to new studies and clinical trials. Further investigations are needed for this technique.
