“…In this strategy, multiple virtual scenarios for resection and reconstruction are combined in a single set of 3D printed guides. In this study, the bone margin status after resection was not reported, so this outcome cannot be compared with the study by Kraeima et al (Kraeima, Dorgelo, et al, 2018;Kraeima, Glas, et al, 2018;.…”

“…The combination of information with regard to localisation, extent, size and shape of the tumour, as provided by CTs and MRIs, is crucial for adequate resection planning (Blatt et al., 2016; Dai et al., 2012; Rana et al., 2012, 2015). Application of this combined CT and MRI workflow has been shown to result in an accurate resection of mandibular tumours with tumour‐free bone margins and no per‐operative deviation from planning (Kraeima, Dorgelo, et al, 2018; Kraeima, Glas, Witjes, & Schepman, 2018; Kraeima, Glas, Steenbakkers, Spijkervet, Roodenburg, & Witjes, 2018). Figure 1 provides a schematic overview of this method, including the postoperative evaluation.…”

“…The risk of developing ORN of mandibular bone is considered to be medium when the bone was exposed to a cumulative dose of 40‐60 Gy and high when the bone was exposed to a cumulative dose >60 Gy (Costa et al., 2016; Lyons & Ghazali, 2008; Reuther, Schuster, Mende, & Kübler, 2003; Wong, Wood, & McLean, 1997). When the original radiation dose is added as a visual volume into 3D‐VSP, this information can support the decision with regard to resection planning (Kraeima, Dorgelo, et al, 2018; Kraeima, Glas, et al, 2018; Kraeima, Steenbakkers, et al, 2018). Yet, there is no consensus in literature with regard to the exact cut‐off for received radiation dose in case of planning a mandibular resection (Marx, 1983; Rice et al., 2015).…”

“…To objectify this (improved), accuracy multiple methods are in use. Usually, a postoperative CT or CBCT is made which is aligned with the preoperative 3D VSP (Baan et al, 2016;van Baar, Liberton, Forouzanfar, Winters, & Leusink, 2019;van Eijnatten et al, 2018;Kraeima, Dorgelo, et al, 2018;Kraeima, Glas, et al, 2018;Schepers et al, 2015). As reported by van Baar et al (van Baar et al, 2019), heterogeneity in evaluation methods limits comparison of postoperative outcomes between studies.…”

Objectives: In case of surgical removal of oral squamous cell carcinomas, a resection of mandibular bone is frequently part of the treatment. Nowadays, such resections frequently include the application of 3D virtual surgical planning (VSP) and guided surgery techniques. In this paper, current methods for 3D VSP leads for optimisation of the workflow, and patient-specific application of guides and implants are reviewed. Recent findings: Current methods for 3D VSP enable multi-modality fusion of images. This fusion of images is not restricted to a specific software package or workflow. New strategies for 3D VSP in Oral and Maxillofacial Surgery include finite element analysis, deep learning and advanced augmented reality techniques. These strategies aim to improve the treatment in terms of accuracy, predictability and safety. Conclusions: Application of the discussed novel technologies and strategies will improve the accuracy and safety of mandibular resection and reconstruction planning. Accurate, easy-to-use, safe and efficient three-dimensional VSP can be applied for every patient with malignancies needing resection of the mandible.

“…There is a lack of studies regarding what residual height of mandibular bone implies a significant fracture risk; however, some authors advise preventive osteosynthesis with a reconstruction plate for residual unaffected bone of 6 mm or less [13]. Despite the sparsity of the literature, virtual surgical planning (VSP) and the computer-aided design/computer-aided manufacturing (CAD/CAM) of surgical guides and reconstruction plates may provide superior outcomes in comparison to conventional approaches and surgical materials [15][16][17][18].…”

Prevention of Mandible Fractures in Medication-Related Osteonecrosis of the Jaws: The Role of Virtual Surgical Planning and Computer-Aided Design and Manufacturing in Two Clinical Case Reports

Background: Marginal mandible resection is required to achieve healing in some cases of medication-related osteonecrosis of the jaws (MRONJ). Despite the sparsity of the literature, computer-aided design/computer-aided manufacturing (CAD/CAM) materials may provide superior outcomes for patients with an increased risk of mandible fracture. The aim of this study was to report a digital workflow for surgical interventions to prevent mandible fracture in MRONJ patients. Methods: We present two cases in which virtual surgical planning (VSP) and CAD/CAM surgical guides and reconstruction plates were used to prevent mandible fractures in elderly MRONJ patients submitted for marginal resection. Two osteoporotic patients, aged 73 and 84 years, presented with stage 3 MRONJ of the right mandibular body with inferior alveolar nerve involvement. The unaffected bone height was 6 mm in both cases, implying a high risk of mandible fracture. After preoperative VSP, surgery was performed through a combined intraoral–transbuccal approach. CAD/CAM-customized cutting guides and reconstruction plates were used for the marginal resection of necrotic bone and internal fixation. Results: Complete healing was achieved and the patients remained asymptomatic up to 1 year post-surgery. Conclusions: VSP and CAD/CAM-customized materials facilitated the complete resection of necrotic bone and rigid fixation in MRONJ patients, allowing a simplified approach with shorter operative times, reduced morbidity, and predictable results.
