In vitro assessment of the accuracy of two intra-oral scanners for post space scanning in a fully digital workflow.

ABSTRACT:

Background

With the rapid advancements in computer-aided imaging, the potential for chairside fabrication of custom-made posts utilizing intraoral scanners may offer a reliable alternative to traditional physical impressions. Accordingly, this study aimed to evaluate the accuracy (trueness and precision) of two intra-oral scanners when different post space diameters were employed. Additionally, the scan depth of each intra-oral scanner (IOS) was assessed.

Methods

An endodontically treated mandibular canine was inserted in a printed typodont model and prepared with two post-space diameters; a small one (1.5 mm) and a large one (2 mm). Polyvinyl siloxane impressions for the two post-space diameters were taken and then scanned with an extra-oral scanner to serve as reference sc
