title: Osteogenesis in a human hydroxyapatite orbital implant 5.5 years after implantation.
abstract: OBJECTIVE
  We report the histological findings of a hydroxyapatite orbital implant 5.5 years after implantation.
  
  
  METHODS
  The hydroxyapatite orbital implant was excised from the left orbit of a 17-year-old female, and it was decalcified and processed for routine light microscopic evaluation.
  
  
  RESULTS
  The implant showed complete fibrovascularization with nearly complete osteogenesis with hematopoiesis.
  
  
  CONCLUSIONS
  Bone may biointegrate throughout the pores of hydroxyapatite orbital implants.
