The application of 3D printing in medical field is more and more extensive and mature. Medical scholars have created a new model for the medical field through continuous research and clinical application, combined with three-dimensional image computer-aided surgery simulation system (CASS). The miracle of saving lives through 3D printing technology has spread all over the world. For example, after installing new vertebrae for mainland men, printing organs for American babies and successfully performing jaw joint surgery for Australian men, Taiwan Province Province also demonstrated its ambition and high standards in this high-tech field. Dr. Xie Mingji, an expert in craniofacial plastic surgery in Taiwan Province Province, said that the application of 3D printing technology in craniofacial plastic surgery has been quite skilled at present, and with the mutual assistance of 3D printing technology and computer 3D navigation, craniofacial plastic surgery can be improved from 90 points to 99 points, which is expected to become the mainstream trend of craniofacial plastic surgery in the future. Dr. Xie Mingji explained that about 60 years ago, in order to treat facial skeletal abnormalities, plastic surgeons had to use plaster models with occlusal devices to achieve the purpose of treatment and correction by simulating the traditional way of imagining patients' faces out of thin air. Due to the limitation of realistic conditions, they often face bottlenecks that can't really solve some problems, such as big face and small face, which can't be improved by occlusal device. Today, there are still many doctors who follow the rules and adopt traditional treatment methods. However, with the birth of 3D printing technology and accurate measurement of CASS, not only the problem of patients' facial size can be solved, but also the orthognathic surgery realm of craniomaxillofacial region can be adjusted and beautified more accurately through 3D navigation technology, which is close to 100% complete symmetry. Moreover, 3D printing technology can also be used to tailor the size of bone materials for craniofacial repair for many patients who go to Korea for bone cutting and those who return to Taiwan Province for help because of excessive or failed bone cutting. Dr. Xie Mingji stated that the quality of bone-cutting plastic surgeons in the workshop is uneven, so everyone must choose doctors carefully. Nowadays, the birth of new technology can improve the accuracy of surgery, the safety of patients and shorten the operation time, and raise medical technology to a new level.
