Digital Analysis of a Novel Impression Method Named the Biological-Oriented Digital Impression Technique: A Clinical Audit

Abstract

This report aims to clinically evaluate the feasibility of a novel biological-oriented digital impression method for teeth prepared with a vertical preparation technique. Something that makes this case unique is that the definitive impression is taken without cord displacement, reducing the invasiveness for the patient. In addition, dental technicians can reproduce the exact emergence profile of the temporary restoration used to reshape the soft tissue contours and define the accurate finish line at the established prosthetic junction, potentially avoiding the aesthetic and biological issues of the double-cord technique. The finish line and emergence profile are transferred using the temporary restoration through a simple CAD procedure performed using the same software used to take the impression. This makes the proposed biological-oriented digital impression technique (BODIT) easy to perform, avoiding adjunctive time and costs for clinicians and patients. Conclusions: Finally, patients' satisfaction could be significantly improved.
