Accuracy of tooth-implant impressions: Comparison of five different techniques.

ABSTRACT:

Purpose

To compare the accuracy of five different tooth-implant impression techniques.

Materials and methods

In this in vitro, experimental study, an acrylic model containing one bone-level Straumann dental implant at the site of maxillary first molar and an adjacent second premolar prepared for a porcelain fused to metal restoration was used. Impressions were made from the model using five different one-step tooth-implant impression techniques including scanning with an intraoral scanner, occlusal matrix, wax relief, closed-tray, and open-tray techniques. Each technique was repeated 15 times. The impressions were poured with dental stone, and the obtained casts were scanned by a laboratory scanner. The scan file of each technique was compared with the scan file of the origi
