Background:

Hydroxyapatite cement (HAC) is a calcium phosphate cement (CPC) designed to overcome limitations of earlier hydroxyapatite materials.
Previous CPCs faced challenges with contouring, compressive strength, and osteoinduction, hindering skeletal reconstruction.
HAC presents enhanced properties for improved clinical applications.

Purpose of the Study:

To evaluate the properties and potential of Hydroxyapatite cement (HAC) for craniofacial reconstruction.
To highlight HAC's advantages over previous hydroxyapatite formulations.

Main Methods:

HAC is prepared as a powder forming an easily applicable paste.
The cement hardens within 6 to 20 minutes.

Properties evaluated include biocompatibility, contourability, stability, and osteoconduction.

Main Results:

HAC demonstrates excellent biocompatibility and stability.
The material is easily contoured in situ.
HAC supports osteoconduction, promoting bone regeneration.

Conclusions:

Hydroxyapatite cement (HAC) provides an excellent reconstructive option for craniofacial defects.
Its properties address the limitations of earlier hydroxyapatite materials, enhancing its utility in skeletal repair.
