Abstract:
Fit accuracy is crucial for the clinical success of implant-supported prostheses. Traditionally, radiographs have been used to assess the marginal fit in 2 dimensions. Three-dimensional (3D) evaluation based on optical scanning techniques requires additional software programs and procedural steps. This article describes an alternative workflow for the rapid verification of the 3D fit of splinted implant-supported crowns. First, the abutments and splinted crowns were positioned onto a printed cast and scanned, with the data exported as a reference. Following the intraoral placement of the abutments and the splinted crowns, an additional scan was made and compared with the reference data to calculate deviations directly within the intraoral scanner. This protocol simplifies the fit evaluation process and provides rapid results, thereby enhancing efficiency and saving time.
