UNASSIGNED: The aim of this study was to investigate the use of computer-aided design and computer-aided manufacturing @entity692 (HA)/ @entity4299 acrylate maleic (EAM) compound construction artificial implants for @entity79 . Computed tomography, computer-aided design/computer-aided manufacturing and three-dimensional reconstruction, as well as rapid prototyping were performed in 12 @entity1 between 2008 and 2013. The customized HA/EAM compound artificial implants were manufactured through selective laser sintering using a rapid prototyping machine into the exact geometric shapes of the defect. The HA/EAM compound artificial implants were then implanted during surgical reconstruction. Color-coded superimpositions demonstrated the discrepancy between the virtual plan and achieved results using Geomagic Studio. As a result, the HA/EAM compound artificial bone implants were perfectly matched with the facial areas that needed reconstruction. The postoperative aesthetic and functional results were satisfactory. The color-coded superimpositions demonstrated good consistency between the virtual plan and achieved results. The three-dimensional maximum deviation is 2.12  0.65mm and the three-dimensional mean deviation is 0.27  0.07mm.No @entity425 or @entity158 was observed at the follow-up examinations. Only 1 implant had to be removed 2 months after the surgery owing to severe @entity281 . No other complication was noted during the follow-up period. In conclusion, computer-aided, individually fabricated HA/EAM compound construction artificial implant was a good craniomaxillofacial surgical technique that yielded improved aesthetic results and functional recovery after reconstruction.
