Abstract This study was per formed to evaluate marginal bone loss using coral bone (NOVOCOR PLUS) versus xenograft (Bio-Oss) in immediate implant placement in esthetic zone. Eighteen Dentis two piece implants were conducted in 18 fresh extraction sockets in ten patients with one or more hopeless teeth indicated for extraction in the region of maxillary anterior teeth. All patients were systemically free and with reasonable oral hygiene. Extraction sockets were randomly distributed into two groups. The first group(group A) received immediate post-extraction implants with bovine xenograft to fill the peri-implant bony defect (jumping gap) While (group B) received immediate post-extraction implants with coral bone to fill the periimplant bony defect.Preoperative measures were performed including clinical and radiographic assessement to ensure proper case selection. A sulcular mucoperiosteal f l ap was raised then an atraumatic protocol wa s followed to deliver the tooth outside the socket. The implants were placed simultaneously in fresh extraction sockets after proper irrigation.The patients of group A received bovine xenograft to fill the marginal gap while group B received coral bone. The bovine xenograft and coral bone were mixed with saline and were introduced inside the gap using a graft carrier and condensers. The graft was packed loosely to allow for pooling of blood between the graft particles |
