The purpose of this article was to describe a fully digital workflow used to perform computer-guided flapless implant placement in an edentulous patient without the use of conventional impressions, models or a radiographic guide. Digital data for the workflow were acquired using an intraoral scanner and cone-beam computed tomography (CBCT). The image fusion of the intraoral scan data and the CBCT data was performed by matching resin markers placed in the patient’s mouth. The definitive digital data were then used to design a prosthetically-driven implant position, surgical template, and computer-aided design/computer-aided manufacturing (CAD/CAM) fabricated fixed dental prosthesis. We believe this is the first published case describing such a technique in computer-guided flapless implant surgery for edentulous patients.
