Abstract
Accurate registration of digital casts and cone beam computed tomography (CBCT) scans
with strong metallic artifacts is essential for the accuracy of guided implant surgery.
This article describes a procedure for mapping digital casts onto CBCT scans containing
significant scatter artifacts in the virtual implant planning stage. The technique
uses a chairside segmented occlusal wing-like radiographic guide, which is constructed
of digital splints fabricated using a desktop 3-dimensional printer and composite
resin spheres as markers to accurately superimpose the bimaxillary digital scans onto
the CBCT scans in a single procedure. This cost-effective technique is timesaving
for clinicians and patients, and the digital information for implant planning can
be collected in a single visit.
