Aligning intraoral scans and cone beam computed tomography scans with beam hardening artifacts: A dental technique.

Abstract

The alignment of patient intraoral scans to cone beam computed tomography (CBCT) scans is often complicated by beam hardening artifacts from multiple dental restorations. Various methods requiring an appliance to be fabricated or flowable composite resin to be added have been described. However, in this straightforward technique, scan alignment with a CBCT scan was achieved in a single visit using only fiducial markers.
