[Discussion on Key Attention in Technical Review for Additive Manufacturing Acetabular Reconstruction Implantable Device].

With the development of additive manufacturing, the advantages of this type implant devices in the treatment of acetabular defects and reconstruction are becoming more and more prominent. The number of registration and declaration of such products is increasing day by day. According to the relevant requirements of the National Medical Products Administration for registration and application documents, combined with the characteristics of acetabular reconstruction implant products made of additive manufacturing, this study analyzes and summarizes the relevant requirements on raw material control, product performance research, product manufacturing, clinical evaluation, et al. We should pay more attention to in the registration and application materials submitted by the applicant. Provide opinions and suggestions for the next registration applicant to standardize product R&D and registration application documents, in order to help them optimize product R&D process, improve product quality and registration application efficiency.
