Calcium Hydroxyapatite Powder
Applications
Bone Grafting and Regenerative Medicine
Bone Substitutes and Grafting: Calcium hydroxyapatite powder is commonly used as a bone graft substitute in orthopedics, dentistry, and spinal surgery. The powder can be mixed with other materials or used alone to fill bone defects, fractures, and trauma sites. It promotes osseointegration, a process by which new bone forms and adheres to the hydroxyapatite, encouraging natural bone healing.
Bone Cement and Coatings: Hydroxyapatite powder is also used to create bone cements that are applied in joint replacement surgeries or to stabilize fractures. Additionally, it is used as a coating for metal implants like titanium or stainless steel to help them integrate more effectively with the surrounding bone.
Spinal and Cranial Surgeries: In spinal and craniofacial surgery, calcium hydroxyapatite powder is utilized to help repair bone loss and fractures, particularly in vertebrae or the skull. It acts as a scaffold, allowing for the growth of new bone tissue in compromised areas.
Dental Applications
Toothpaste and Remineralization: One of the most popular uses of calcium hydroxyapatite is in toothpaste and other oral care products. The powder is included in these products because it helps to remineralize tooth enamel that may have been eroded due to acidic foods, brushing, or tooth decay. It restores essential calcium and phosphate ions to the enamel, enhancing its strength and resilience.
Dental Fillings: Calcium hydroxyapatite is also used as a filler material in dental restorations such as fillings, crowns, and bridges. Because of its high biocompatibility and ability to bond with natural tooth structures, it provides a durable and aesthetic solution for dental repairs.
Bone Grafting for Dental Implants: In cases where the patient has insufficient bone for supporting dental implants, calcium hydroxyapatite powder can be used in bone grafting procedures. The powder can be mixed with autologous bone (bone taken from the patient) or other synthetic materials to fill the gaps and encourage bone formation, allowing for the successful placement of dental implants.
