Within the limitation of this in vitro study, in maxillary anterior immediate implant placement, the scanning showed consistent high accuracy (<30 μm) across the tested depth levels. Also, the angular deviations were consistently low (<0.1 degrees). A digital workflow using an intraoral scanner and scan body should be clinically applicable for immediate implant placement and provisionalization scenarios within a range of scan body exposures incisal to the mucosa.
