Coral hydroxyapatite for cheekbone augmentation?

 In our practice we have been using Silastic cheek implants for over 25 years and have an excellent success rate.  They are easy to place in through an intraoral approach, and they're also easy to remove if ever needed. It's important to be able to easily remove them if ever needed, rather than tissue integration occurring which causes more trauma for removal

Coral
hydroxyapatite if properly placed can produce the same projection as an
implant. Implant placement usually requires an operation with more exposure and
hence, more swelling than coral hydroxyapatite placement.

This material has been used to augment cheeks, the trouble is that as far as I know it is done open, a space is made and the HA is packed into the space. It's duration is good but you wont get the same projection that an implant can provide. YOu also need an incision and exposure.
