A review: recent advances in the application of 3D printing biomaterials in breast reconstruction research

Breast reconstruction is an indispensable component of surgical treatment for breast cancer. Currently, implant-based breast reconstruction (IBBR) has become a primary method, utilizing prosthetic implants. The advantages of implantation, such as fewer complications, safety, and convenience, have made it a research hotspot in recent years. Among implant materials, high-polymer materials stand out due to their lightweight, cost-effectiveness, high plasticity, and good biocompatibility, making them the most promising choice. Simultaneously, with the advancement of 3D printing technology, some 3D-printed prosthetic scaffolds have gradually emerged in breast reconstruction research and even in clinical applications. Therefore, this review briefly discusses the historical development of high-polymer biomaterials and related technologies in breast reconstruction. It also primarily explores the progress in the application of newly developed artificial implants, especially those based on emerging technologies like 3D printing. The purpose of this review is to provide a comprehensive summary of the past and present developments in breast reconstruction, aiming to contribute to the synthesis of clinical advancements and future research directions in this field.
