Abstract

Objectives: Improvement in the functional performance and biocompatibility of biomedical implants using different bioactive materials and coating techniques. Methods/Statistical Analysis: The requirement of bio activity, biocompatibility with proficient mechanical properties without immune rejection for long lasting implants and bone substitutes is a tremendous challenge. These bone substitute structures ought to be set up for individual patients with all details controlled on the micrometer level. Findings: The metallic implants (Ti-alloys, Co-alloy and Stainless steel) utilized by researchers to investigate bone fractures and imperfections are unsuccessful to perform in biomedical applications as they failed to build required bond with living bone. The scientists proposed combining the bio activity of bioactive materials and excellent mechanical properties of metals by depositing bio active materials on metal base material. Application/Improvements: Many methods like plasma spraying, thermal spraying, pulsed laser ablation, sputter coating, etc., were utilized to efficiently coat bioactive materials on metal base. In this paper, we will review the bioactive materials including different methods utilized in depositing bio-ceramics and effect of cryogenic processing on biomedical implants.
