Abstract:
A prosthetically-driven virtual implant plan is considered a challenging procedure depending on accurate registration of the three-dimensional optical surface scan and 3D volumetric rendering reconstructed from cone-beam computed tomography (CBCT) images. However, the presence of preexisting metal restorations may significantly negatively influence the registration process. This technical report describes a novel digital workflow to optimize the implant planning outcome for the partially edentulous patient with preexisting metal restorations by accurately aligning the standard triangle language data of the intraoral scanner with the CBCT rendering using a dual-scan technique and an appliance with radiographic markers.
