“…Along with recent technical advances (Flügge et al., 2016; Hilgenfeld, Prager, et al, 2018; Prager et al., 2015; Sedlacik et al., 2016), in vivo application of three‐dimensional (3D) dental magnetic resonance imaging (dMRI) has attracted growing interest in dentistry. This non‐ionizing dental imaging technique has already demonstrated high accuracy and reproducibility in 3D evaluation of periodontal soft tissues (Heil et al., 2018; Hilgenfeld, Kastel, et al, 2018) and peri‐implant bone defects (Hilgenfeld, Juerchott, et al, 2018). However, further research is needed to evaluate the clinical applicability of dMRI in the field of periodontology.…”

Aim To investigate the accuracy and reliability of dental magnetic resonance imaging (dMRI) in assessing maxillary molar furcation involvement (FI). Material and Methods In this prospective study, 22 patients with severe periodontitis underwent cone‐beam computed tomography (CBCT) and dMRI. For 192 furcation entrances, the degree of horizontal FI was assessed by two independent observers on both modalities. Results of dMRI were compared with CBCT (reference modality) to assess the accuracy of dMRI. Cohen's kappa (κ), sensitivity and specificity were calculated for FI classification. Bland–Altman analysis and the Kruskal–Wallis test were used to evaluate measurement accuracy of dMRI. Results Based on CBCT findings, 93 furcation entrances revealed FI (degree I/II/III: 35/19/39). Intra‐ and inter‐reader agreement was excellent for both modalities (κ‐range: 0.884 to 0.933). dMRI measurements showed high agreement with CBCT (bias: 0.17 mm; 95% limits of agreement: −1.05 to 1.38 mm), and measurement accuracy did not differ among different degrees of FI (p = .67). For FI detection, sensitivity and specificity of dMRI were 98% and 99%. For FI classification, sensitivity values of dMRI were 89%/84%/100% for degree I/II/III. Conclusions Compared to CBCT (non‐invasive gold standard), dMRI demonstrates high accuracy and reliability in evaluating the degree of FI in maxillary molars.

“…Dental magnetic resonance imaging (dMRI) is a promising new diagnostic tool in dentistry (Di Nardo, Gambarini, Capuani, & Testarelli, ) with potential fields of application in endodontics (Iohara et al, ), implantology (Duttenhoefer et al, ), orthodontics (Heil et al, ), and periodontology (Hilgenfeld et al, ). Recently, dMRI attracted attention for study of zirconia implants (Benic, Elmasry, & Hämmerle, ; Hilgenfeld et al, ), and excellent contrast and limited artifacts have been observed (Duttenhoefer et al, ).…”

“…Such direct nerve visualization may be beneficial for presurgical planning prior to implant dentistry but also prior to other procedures such as wisdom tooth removal or orthognathic surgery 8,28 . Within the context of implant surgery, MRI enables the measurement of mucosal thickness and may help planning of palatal tissue harvesting 41 . MRI may also enable postoperative evaluation of implants 18,19,42 and may offer the opportunity for detecting peri‐implant bone defects 3‐dimensionally 36 .…”

Background: Computer-guided implant surgery is currently based on radiographic techniques exposing patients to ionizing radiation. Purpose: To assess, whether computer-assisted 3D implant planning with templateguided placement of dental implants based on magnetic resonance imaging (MRI) is feasible. Materials and methods: 3-Tesla MRI was performed in 12 subjects as a basis for prosthetically driven virtual planning and subsequent guided implant surgery. To evaluate the transferability of the virtually planned implant position, deviations between virtually planned and resulting implant position were studied. Matching of occlusal surfaces was assessed by comparing surface scans with MRI-derived images. In addition, the overall image quality and the ability of depicting anatomically important structures were rated. Results: MRI-based guided implant surgery with subsequent prosthetic treatment was successfully performed in nine patients. Mean deviations between virtually planned and resulting implant position (error at entry point 0.8 ± 0.3 mm, error at apex 1.2 ± 0.6 mm, angular deviation 4.9 ± 3.6), mean deviation of occlusal surfaces between surface scans and MRI-based tooth reconstructions (mean 0.254 ± 0.026 mm) as well as visualization of important anatomical structures were acceptable for clinical application. Conclusion: Magnetic resonance imaging (MRI) based computer-assisted implant surgery is a feasible and accurate procedure that avoids exposure to ionizing radiation.
