　　Calcium phosphate bone cement（CPC）has been successfully used to reconstruct small bone defects in the field of orthopedics and neurosurgery. This product contains calcium phosphate powder, and it can facilitate the modeling and reconstruction of deformities when used as a paste.
　　Surgical treatment of facial fractures usually requires weeks for satisfactory reconstruction. In some cases, surgical correction cannot be carried out after severe facial fractures with bone dislocation that caused facial contour deformity or enophthalmos. Here, we report two cases of severe facial deformity due to prolonged orbital and zygomatic fractures. The region was approached infraorbitally, and CPC was applied to correct infraorbital and malar depression as an onlay implant.
　　In our experience, this material can be applied not only for reconstruction of bone defects, but also for correction of facial contour deformity due to prolonged orbital and zygomatic fractures.
