Calcium Apatite Crystals used at a graft extraction site are a form of which mineral category?

• A. Calcium Phosphate
• B. Calcium Carbonate
• C. Silicon Dioxide
• D. Magnesium Phosphate

Answer: (A)

Calcium phosphate is the category. Calcium apatite crystals belong to the apatite group, which are minerals where calcium combines with phosphate. Hydroxyapatite, the most well-known form, is a major component of natural bone mineral and is widely used as a bone graft substitute because it provides an osteoconductive scaffold for new bone growth. The other options—calcium carbonate, silicon dioxide, and magnesium phosphate—are different minerals with distinct compositions (CaCO3, SiO2, and a magnesium-dominated phosphate, respectively) and do not represent the calcium phosphate family.
