Influence of 3d printing technology on biomedical applications: a study on surgical planning, procedures, and training

Abstract

The adaptation of advanced technologies in the medical sector has tremendously enhanced the surgical and treatment procedures. Advance manufacturing technology like 3D printing is influencing the pre-operative surgical planning procedures. Moreover, the technology is being used to print complex anatomical models for medical training purposes. Surgical assistive devices and medical equipment are also being fabricated using this technology. However, the adaptation of this technology by the healthcare sector in developing countries is still a challenge. Partially due to lack of awareness regarding the potential of the technology and partially due to the increased surgical cost associated with it. Therefore, it is crucial to demonstrate the prospects of this technology in the biomedical area. In this regard, an attempt has been made to exhibit the application of 3D printing technology in the area of surgical planning, medical training, and customized surgical devices. The present paper outlines the process flow for 3D printing of biomedical models from medical images. Moreover, the paper also presents the case studies for the utilization of 3D printing technology in pre-operative surgical planning of tibial plateau fracture, fabrication of artificial temporal bone for mock surgery and educational purpose, and for the fabrication of the orthodontic drill guides.
