In the pursuit of tailored properties for applied bioceramics in bone graft applications, a personalized mixture of precursor base materials is crucial. Hydroxyapatite (HA), beta tricalcium phosphate (β-TCP), and versatile biopolymers serve as base materials to produce personalized mixtures, each presenting its own set of advantages and disadvantages. Combining these materials addresses limitations of individual components, but further improvements require exploring alternative base materials with distinct properties. This study introduces beta calcium pyrophosphate (β-CPP) as a valuable addition to the base materials, exhibiting intermediate biodegradation properties. When combined with biopolymer alginate, β-CPP enables the fabrication of personalized porous 3D scaffolds. Despite β-CPP being an unwanted by-product in mineralized tissue regeneration, this research demonstrates its innovative potential in stimulating cell interaction within porous 3D structures. The β-CPP/Alginate 3D Scaffold, with a 5:3 w/w ratio, significantly enhances mineralization activity compared to the control. This novel composite, showcasing interconnected cells throughout the 3D structure, presents a promising avenue for mineralized tissue regeneration. The study underscores the importance of optimizing both biodegradation and mechanical features in new bioceramics, highlighting β-CPP as a noteworthy candidate with potential commercial implications.

Biomaterials are in use for the replacement and reconstruction of several tissues and organs as treatment and enhancement. Metallic, organic, and composites are some of the common materials currently in practice. Metallic materials contribute a big share of their mechanical strength and resistance to corrosion properties, while organic polymeric materials stand high due to their biocompatibility, biodegradability, and natural availability. To enhance the biocompatibility of these metals and alloys, coatings are frequently applied. Organic polymeric materials and ceramics are extensively utilized for this purpose due to their outstanding characteristics of biocompatibility and biodegradability. Hydroxyapatite (HAp) is the material from the ceramic class which is an ultimate candidate for coating on these metals for biomedical applications. HAp possesses similar chemical and structural characteristics to normal human bone. Due to the bioactivity and biocompatibility of HAp, it is used for bone implants for regenerating bone tissues. This review covers an extensive study of the development of HAp coatings specifically for the orthopaedic applications that include different coating techniques and the process parameters of these coating techniques. Additionally, the future direction and challenges have been also discussed briefly in this review, including the coating of HAp in combination with other calcium magnesium phosphates that occur naturally in human bone.
