The increasing need for joint replacement surgeries, musculoskeletal repairs, and orthodontics worldwide prompts emerging technologies to evolve with healthcare's changing landscape. Metallic orthopaedic materials have a shared application history the aerospace industry, making them only partly efficient in biomedical domain. However, suitability of metallic bone tissue replacements regenerative therapies remains unchallenged due their superior mechanical properties, eventhough they are not perfectly biocompatible. Therefore, exploring ways improve biocompatibility is most critical step toward designing next generation biomaterials. This review discusses methods improving metals used devices using surface modification, bulk incorporation biologics. Our investigation spans multiple length scales, from effect microporosities, nanoarchitecture, biomolecules such as DNA enhanced biological response materials. We examine recent 3D printing alloy design storing charge on nanoarchitecture surfaces, metal-on-metal, ceramic-on-metal coatings present coherent comprehensive understanding subject. Finally, we consider advantages challenges biomaterials identify future directions.

The adoption of laser powder bed fusion (L-PBF) for metals by the industry has been limited despite significant progress made in development process chain. One key obstacles is inconsistency parts obtained from L-PBF. Due to its complexity, there are many potential fluctuations that can occur within chain which lead quality L-PBF parts. Machine learning (ML) possibility overcome this obstacle utilising datasets at various stages In perspective article, integration ML into different chain, potentially better control, explored. Prior L-PBF, be used part designs and file preparation. Then, algorithms applied parameter optimisation situ monitoring. Finally, also integrated post-processing.

Currently, metal implants are widely used in orthopedic surgeries, including fracture fixation, spinal fusion, joint replacement, and bone tumor defect repair. However, conventional difficult to be customized according the recipient's skeletal anatomy characteristics, leading difficulties meeting individual needs of patients. Additive manufacturing (AM) or three-dimensional (3D) printing technology, an advanced digital fabrication technique capable producing components with complex precise structures, offers opportunities for personalization. We systematically reviewed literature on 3D over past 10 years. Relevant animal, cellular, clinical studies were searched PubMed Web Science. In this paper, we introduce method characteristics biometals summarize properties their applications surgery. On basis, discuss potential possibilities further generalization improvement. technology has facilitated use different procedures. By combining medical images from techniques such as CT MRI, allows based injured tissue. Such patient-specific not only reduce excessive mechanical strength eliminate stress-shielding effects, but also improve biocompatibility functionality, increase cell nutrient permeability, promote angiogenesis growth. addition, advantages low cost, fast cycles, high reproducibility, which can shorten patients' surgery hospitalization time. Many trials have been conducted using implants. modeling software, operation equipment, demand implant materials, lack guidance relevant laws regulations limited its application.
