Bonegraft Question

Hi, my doctor did a bonegraft on me during surgery and he used a mixture of my own bone, with freeze-dried demineralized bone (from a bone bank) and Hydroxylapatite (a man made calcified product to stimulate bone growth)… Will my body absorb the Hydroxylapatite or will that stay with my bone permanently? Thank you.

Answer: Hydroxyapatite in bone graft

By Sarah h
Dental Professional

Your body will absorb the hydroxyapatite in the bone graft material.  Hydroxyapatite is used to produced a pure osteoconductive property.  This creates a suitable environment for new bone formation.  However, the absorption of hydroxyapatite crystals is a very slow process.  Sometimes they can be seen for years after the bone graft has been placed.  Bone growth around these crystals is excellent and they have great biological safety, biocompatibility and bone conduction.
