In bio-medicine, new ceramic materials could be used to create artificial bones, such as dentures used in dentistry. Hydroxyapatite is a natural bone mineral that can be synthesized from some biological and chemical raw materials and can be made into ceramic materials. Orthopedic implants made from these materials can better bond to bone and other tissues in the body without rejection and inflammation. Most hydroxyapatite ceramics are porous and lack sufficient mechanical strength, so they are often used as metal coatings to bind more tightly to bone, or as bone fillers. They can also be used as fillers for orthopedic plastic screws to reduce inflammation while making the plastic orthopedic material more resorbable. The current work is to make them stronger by producing dense nanoscale crystalline hydroxyapatite ceramic materials, to a standard that can be used in orthopaedic applications that require weight-bearing devices, so that although synthetic but naturally present in bone can be used minerals to replace foreign metal and plastic orthopaedic products. The ultimate goal of research into these ceramics is that they can replace bone, or have them bind collagen to synthesize bone.
