Objective:
To explore the application prospects of EH compound artificial bone material combined with computerized three-dimensional reconstruction in craniomaxillofacial surgery.
Methods:
Computed tomographic scan, computer-aided design/computer-aided manufacturing three-dimensional reconstruction, and rapid prototyping were conducted on 39 patients during 2005 to 2008. An EH compound artificial bone material was made into the exact geometric shapes of the defect to be corrected and then implanted during surgical reconstruction.
Results:
The EH compound artificial bone implants were perfectly matched with the facial areas needed for repair. The reconstructed faces were symmetric on the whole, and postoperative results were satisfying.
Conclusions:
The EH compound artificial bone material combined with computerized three-dimensional reconstruction offers a new method in craniomaxillofacial surgical practice. Aesthetic results after reconstruction surgery can therefore be effectively improved.
