Abstract:

BACKGROUND: Additive material manufacturing technology is widely used in the treatment of bone defects because of its advantages of rapid and accurate preparation of prostheses.
OBJECTIVE: To review the current situation of material addition technology applied in bone defects.
METHODS: The first author searched the articles related to additive manufacturing and bone defect repair in PubMed, CNKI, and WanFang databases published from 2000 to 2018. The keywords were “bone defect, additive manufacturing (AM), 3D printing, bone tumour” in Chinese and English, respectively.
RESULTS AND CONCLUSION: (1) The additive manufacturing technology can rapidly reconstruct the three-dimensional prosthesis in vitro with modern imaging technology. (2) In the treatment of bone defects, we cannot only establish the model of bone defects before operation to simulate the operation, familiarize and compare the operation methods, and effectively reduce the operation time, but also can quickly and accurately prepare different varieties of implants, significantly improving the success rate of surgery. (3) Additive manufacturing technology shows good prospects in the clinical application of bone defects.

Key words: additive manufacturing, bone defects, bone repair, bone tumor, three-dimensional reconstruction, simulating surgery, quick and accurate preparation, implants, the National Natural Science Foundation of China
