Abstract

Background: A digital workflow for implant-supported fixed complete prostheses (ISFCP) using photogrammetry (PG), virtual articulator (VA), and virtual facebow (VF) data remains a challenge.

Methods: The novel ISFCP technique included four steps: (1) formation of a dynamic virtual patient, (2) integration of PG data, (3) fabrication of a diagnostic ISFCP, and (4) fabrication of a definitive ISFCP and test of the deviation.

Results: Dynamic virtual patients were formed by integrating PG, VA, and VF data. The cumulative root mean square deviation between the designed data and actual definitive prosthesis was 140.4 µm.

Conclusions: The novel technique for ISFCP fabrication described in this paper can help optimise the clinical efficiency and quality of ISFCP but requires an initial learning curve.

Clinical significance: This technique provides a direct workflow, using PG, VA, and VF data, to fabricate ISFCP based on the provisional restoration.

Keywords: Implant-supported full-arch prosthesis; Photogrammetry; Virtual articulator; Virtual patient.
