“…[8] In a mandibular reconstruction with the fibula, Foley et al reported that the average error was 2.7 mm at the condylar position and 2.5 mm at the gonial angle, when they used both a mandibular cutting guide and a fibula bone cutting guide, prepared with a 3D surgical simulation plan. [1] However, in the present study, the error at the condylar position was large, despite our use of a STL surgical template guide. We found an average 3D distance error of 15.49 mm with the STL surgical template guide and 25.15 mm with the manual method at the condylar lateral point.…”

“…Based on the results of preoperative mandibular reconstruction simulation and planning, information required for the surgery, such as the position of the osteotomy line and the bone movement, is converted into stereolithography (STL) data and used to prepare a surgical guide. [1] After resecting the mandible, a precise reconstruction of the external features of the mandible requires a preoperative simulation of the mandible with the fibula. With this approach, the fibula graft bone segments could be cut to smaller sizes for a more elaborate reconstruction.…”

Objective: We examined whether cutting a fibula graft with a surgical guide template, prepared with computer-aided design/computer-aided manufacturing (CAD/CAM), would improve the precision and accuracy of mandibular reconstruction. Methods: Thirty mandibular rapid prototype (RP) models were allocated to experimental (N ¼ 15) and control (N ¼ 15) groups. Thirty identical fibular RP models were assigned randomly, 15 to each group. For reference, we prepared a reconstructed mandibular RP model with a three-dimensional printer, based on surgical simulation. In the experimental group, a stereolithography (STL) surgical guide template, based on simulation, was used for cutting the fibula graft. In the control group, the fibula graft was cut manually, with reference to the reconstructed RP mandible model. The mandibular reconstructions were compared to the surgical simulation, and errors were calculated for both the STL surgical guide and the manual methods. Results: The average differences in three-dimensional, minimum distances between the reconstruction and simulation were 9.87 ± 6.32 mm (mean ± SD) for the STL surgical guide method and 14.76 ± 10.34 mm (mean ± SD) for the manual method. Discussion: The STL surgical guide method incurred less error than the manual method in mandibular reconstruction. A fibula cutting guide improved the precision of reconstructing the mandible with a fibula graft. ARTICLE HISTORY

“…The reasons for such trend are to be found in the present state-of-the-art in this technology, as well as the ever growing need for fast and high-precision manufacture of parts of human anatomy. Thus, CAD is today being intensively used in the biomedical industry -from the software for generation of virtual anatomical models, to the design of custom-made medical implants, to tissue and bone engineering [3,4]. Bearing in mind the complexity of human anatomy, this has been made possible primarily due to developments in the field of Reverse Engineering (RE) and systems for 3D-digitalization [5][6][7][8].…”

Personalized bone grafts are one of the best examples of the latest achievements in the biomedical engineering. In the area of maxillofacial bone tissue reconstruction or jaw bone augmentation, their application has for some time been on the rise, and its ever increasing significance is driven by the growing technical support. One of the key segments is the bone graft modelling customized to suit patient's specific needs, since it greatly determines not only the future anatomic functionality but also the acceptance probability of the graft by the bone tissue. With the graft geometry importance in mind, presented in this paper is an approach to personalized bone graft modelling. The approach is based on application of modern computer-aided systems and methods, and enables efficient geometric design while minimizing the risk of errors during modelling and placement stages. Verification is based on a case study of a personalized bone graft designed for a patient requiring mandible augmentation.

Recently, computer-assisted surgery is popular for performing well-planned operations. Computer-aided navigation system is helpful in maxillofacial surgery with real time instrument positioning and clear anatomic identification. Generally, segmental mandibulectomy and reconstruction flap surgery have done by extra-oral approach such as, submandibular approach. This case report describes performing intra-oral segmental mandibulectomy and reconstruction with monocortical deep circumflex iliac artery (DCIA) flap and CT guided implant surgery by using computer-aided surgical guide and navigation for managing ameloblastoma in a 31 years old female patient.Key WordsZZComputer-aided surgery ㆍNavigation surgery ㆍMandibulectomy ㆍDCIA flap ㆍCT guided implant surgery.
