MRI for dental implant planning. Technical information is given in Supplementary Table 8.

Authors Study design/subjects Research question Findings
Flügge et al. 2020 58 5 patients Feasibility of dental implant planning using CAD/CAM processes based on MRI
  • MRI and optical surface scans for virtual implant planning and production of drill guides, - no post-operative control of implant positions

Hilgenfeld et al. 2020 62 30 patients Accuracy and reliability of dental implant planning based on MRI, comparison to dental implant planning based on CBCT
  • Excellent interrater agreement for implant planning in MRI,

  • excellent intermodality agreement for MRI and CBCT,

  • adequate prediction of implant type, length and diameter, in pre-operative MRI,

  • mean deviations between MRI planning and actual implant position were 1.1 ± 0.7 mm at implant shoulder, 1.3 ± 0.7 mm at implant apex and 2.4 ± 1.5° angular deviation, respectively

Probst et al. 2020 59 12 patients Feasibility of dental implant planning using CAD/CAM processes based on MRI, comparison of planned and actual implant positions
  1. Mean deviation between planned and actual implant position were 0.8 ± 0.3 mm at implant shoulder, 1.2 ± 0.6 mm at implant apex and 4.9 ± 3.6° angular deviation, respectively

Schwindling et al. 2021 60 27 patients, 41 implants Accuracy of PIGS based on MRI
  • Accuracy slightly lower than reported for CBCT based guided surgery

  • mean deviation between planned and actual implant position: 1.7 ± 0.9 mm entry point, 2.3 ± 1.1 mm apex, 7.1 ± 4.8° axis

  • mean deviation between planned and actual implant position in CBCT: 1.9 ± 1.7 mm entry point, 2.5 ± 1.5 mm apex, 6.8 ± 3.8° axis

Grandoch et al. 2021 61 16 patients, 22 implants Comparison of MRI and CBCT-based dental implant planning
  • CBCT-based planning received “ideal” rating in all cases, for 3D HR T1w TSE “ideal” rating was achieved for 81.9% of cases and ‘improvable’ rating for 18.1% for 3D HR T1w FFE ‘ideal’ 54.2% ‘improvable’ 30.0% ‘not acceptable’ 15.3%

  • differences between implant positions in CBCT and MRI: apical position 1.2 ± 0.7 mm and 1.3 ± 0.5 mm coronally, 3.0 ± 1.2 degrees. distance to the mandibular canal significantly higher with MRI: 1.3 ± 0.8 mm

CBCT, cone-beam CT; PIGS, partially guided dental implant surgery.
