A Clinical Comparative Study of 3-Dimensional Accuracy between Digital and Conventional Implant Impression Techniques.

Purpose: To evaluate the accuracy of a digital implant impression technique using a TRIOS 3Shape intraoral scanner (IOS) compared to conventional implant impression techniques (pick-up and transfer) in clinical situations.

Materials And Methods: Thirty-six patients who had two implants (Implantium, internal connection) ranging in diameter between 3.8 and 4.

Effect of Splinting on Dimensional Accuracy of Impressions Made of Implants with Different Subgingival Alignments.

Purpose: Placement of implants at deeper levels of gingiva is sometimes inevitable because of issues like esthetics or bone availability. The accuracy of impressions may be affected in these situations. The aim of this in vitro study was to evaluate the effects of splinting and length of impression copings on the accuracy of impressions made of deeply placed implants.
