Effect of Implant Angulation and Depth on the Accuracy of Casts Using the Open Tray Splinted Impression Technique.

The purpose of this study was to evaluate the accuracy of open tray dental implant impressions when the implants are placed with varying implant angulations and depths. Four partially edentulous models were fabricated using photopolymer resin, each having different angulation and depth of the implant analogs. A total of 40 open tray elastomeric impressions were made, which were poured in type IV die stone (n = 10).
