“…However, to the best of our knowledge, the design of such implants nowadays is much dependent only on the essential experience of surgeons [4]. One way to prevent such failures is to employ preoperative finite element (FE) analysis to predict structural strength and assist the design of implants [5][6][7].…”

“…At the time of design the surgeon finalized the tumor size, surgical margin, cutting locations, screw locations, and number of screws needed. Rapid prototyping offers preoperative fabrication of customized implants . Numerous rapid prototyping techniques (EBM, SLS or DMLS) have been developed for the fabrication of such a highly complex individual shape implants in metal forms like titanium or cobalt chrome.…”

Objectives: The aim of this work was to compare different 12 cases (3 patients * 4 cases = 12 cases) with varying gaps between implant and bone by analyzing the effect of these gaps on implant and screws using FEM. Methods:In each patient's case 1 using CSOG and in case 2, 3, and 4 without using CSOG tumor cutting was done. Hence in each patient zero gaps at case 1 and overcutting at case 2, 3, and 4 have obtained at different locations.Results: FEM results reveal that in each patient's case 4 (maximum gap) was more susceptible to loosening of the screws due to higher strains (37%) and implant failure due to higher stress (28%) concentration under the same loading conditions when compared with case 1 (zero gap). Conclusions:The study reveals that mandibular reconstruction with implant placement using CSOG can significantly enhance the stability and safety of the implant.

Additive manufacturing (AM), widely known as three-dimensional printing-3D printing, represents a disruptive innovation in healthcare sector. It is an innovative technology with great potential and economic implications. During the past few years, the improvement in 3D printing technologies and the availability of various printable materials (Stansbury & Idacavage, 2016; Youssef et al., 2017) have resulted in an increase in the number of companies that are leasing 3D printers to the users or on-demand printing services. The economic implications of such possibilities are significant in healthcare (Frost & Sullivan, 2019) because the manufacturing can be outsourced to a third party that may be providing manufacturing services onsite or off-site from the patient-specific custom models. The possibility to apply AM in the biomedical sector is extremely interesting for medical device manufacturers because on-demand manufacturing allows eliminating inventory and printing only the components that are needed at a given time. Personalized medical devices, specifically based on CT-scan
