A technique for in vitro fit assessment of multi-unit screw-retained implant restorations: Application of a triple-scan protocolKeywords: computer-aided design/computer-aided manufacturing , digital dentistry , fit assessment , implant , prosthetics Abstract: Recent advances in industrial non-contact scanners offer unprecedented opportunities for quality assessment of dental restorations. The majority of investigations published to date are limited to local two-dimensional results. A triple-scan protocol for virtual fit assessment of multi-unit screw-retained implant restorations is presented in this technical report. The advantages for application in biomechanical research include detailed three-dimensional information on internal component congruence in implant superstructures to be used in mathematical models.
