: Some study subjects or cohorts have been previously reported in:Hilgenfeld T, Juerchott A, Deisenhofer UK et al (2019) In vivo accuracy of tooth surface reconstruction based on CBCT and dental MRI-A clinical pilot study. Clin Oral Implants Res 30:920–927.The previous study assessed the spatial accuracy of tooth-surface reconstructions based on dental MRI and CBCT data. Altogether, 18 study subjects of the current patient cohort participated in the previous study as well. Imaging of tooth surfaces within MRI data resembles an essential intermediate step in guided dental implant surgery. Tooth surfaces are used for co-registration of spatially highly accurate oral surface data (derived from intraoral scans or digitalized models) and CBCT data. The previous publication introduced a new method to visualize tooth surfaces in dental MRI and compared it’s accuracy with the accuracy of CBCT, using a digitalized model as reference. It evaluated, however, not the accuracy and reliability of dental MRI for implant planning.
