A myriad of extirpative surgical protocols for the management of benign tumors of the jaws have been presented in the literature. Through significant advancements in computer-aided design and computer-aided manufacturing (CAD/CAM) technology and surgical instrumentation, today surgeons have at their disposal robust technology-driven techniques that are aimed at improving surgical outcomes. Our goal is to investigate the benefits of implementing virtual surgical planning (VSP) in conjunction with piezoelectric surgery (PES) to ensure success while minimizing the risk of complications during extirpation of tumors of the mandible. This case report describes the successful extirpation of an ossifying fibroma of the mandible in an adult patient using both VSP and PES.

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.

Segmental Mandibulectomy

Cemento-ossifying fibroma (also known as ossifying fibroma or cementifying fibroma) is a benign osteogenic neoplasm. Pain and paresthesia are rarely associated with cemento-ossifying fibroma; thus, nerves must be preserved during excision. With the advent of computer-aided techniques, the use of virtual surgical planning and a customized template can improve the precision of resection and reconstruction, reduce operating time, and improve postoperative outcomes. In this report, we describe a case of cemento-ossifying fibroma in a female patient who underwent segmental mandibulectomy and reconstruction with an iliac bone graft. Additionally, we describe a simple and effective way to preserve the inferior alveolar nerve.

Oncological resection followed by reconstruction with a free fibular graft is still considered to be the gold standard treatment for functional and prosthetic rehabilitation of oral cancer patients. But this tedious traditional process is challenging for surgeons, as they have to deal with associated curve anatomy, surrounding innervations, and maintenance of functional and aesthetical acceptability. Such manual and operator’s skill dependent surgery can commonly demand a longer treatment duration; leading to an increased risk for prolonging the period of ischemia with increased morbidity, which frequently ends with an uncertain, unsatisfactory outcome. Technological advancements in the 20th and 21st centuries present a revolutionary improvement in the field of reconstructive surgery. Virtual surgical planning (VSP) and threedimensional (3D) bio-printing incorporating computer-aided design and computer-aided modeling is a promising tech in modern head and neck reconstruction. This recent innovation is more polished regarding initiation of patient-customized models, pre-bent plates, and osteotomy guides which further increase surgical precision, improve operative efficiency, ensure proper wound healing, shorten operative time, reduce operative cost, and decrease morbidities. This review focuses on the virtual surgical planning and 3D bio-printing technologies to evaluate their efficiency of qualitative and quantitative outcomes of resection and reconstruction of mandible in head-neck cancer using fibular graft.

In this article, the advantages, disadvantages and pitfalls of three-dimensional virtual surgical planning (3D-VSP) compared to traditional two-dimensional (2D) planning methods in orthognathic surgery are discussed, alongside a standardised protocol that can be utilised. A skeletal Class II, skeletal Class III and an anterior open bite clinical case along with their 3D-VSP management are presented, highlighting modifications that can be made to computer-aided design/computer-aided manufacture (CAD/CAM) cutting guide and plate designs.
