1. Hydroxyapatite (HA): This is the primary mineral component of natural bone and provides strength and rigidity.
2. Tricalcium Phosphate (TCP): This is another calcium phosphate compound, often used in combination with HA. It is less stable than HA and can be bioresorbable, meaning it is gradually broken down by the body. This property is beneficial for bone regeneration, as it allows the synthetic material to be replaced with natural bone over time.
3. Beta-Tricalcium Phosphate (β-TCP): This is a specific form of TCP with enhanced bioactivity and bioresorbability. It aids in osteoconduction (guiding bone growth) and osteoinduction (stimulating new bone formation).
These components can be combined in various proportions depending on the desired properties of the synthetic bone. For example, a higher proportion of HA might be used for a more rigid implant, while a higher proportion of TCP might be used for a more bioresorbable implant.
