This study was designed to assess the bone reaction formation around porous hydroxyapatite(PHA) and coral implants inserted into non-healing mandible defect using light, confocal and scanning electron microscopy. Blocks 4 mm x 4 mm x 4 mm were prepared from sea coral porites species and porous hydroxyapatite. Six-week old, ten male rabbits were divided into two groups. First group was implanted with coral blocks at the right non-healing defect of the rabbit mandible. Second group was implanted with porous hydroxyapatite, while the left mandible in both groups acted as control. Implants were harvested at 2 and 4 months intervals and prepared for light, confocal and scanning electron microscopy. Light microscopy, confocal microscopy and SEM revealed complete and good osseointegration between implant materials and host bone in addition to new bone formation in the mandibular defects implanted with coral blocks as well as in the porous hydroxyapatite , although there was greater amount of bone formation in coral group. All control left mandibles was exhibited few-separated island of new bone formation but large defect area was seen. In conclusion, light microscopy; confocal microscopy and SEM were effective tools to assesse bone formation around the implant materials and both coral and porous HA were good implant materials that can be accelerate bone healing and resorb in acceptable time. Both materials showed similar resorption mechanism due to similarity in their osteoconductivity and biodegradability properties.

KEYWORDS: Coral, porous hydroxyapatite , Mandible, Osseointegration.
