Assessment of Deproteinized Bovine Bone for Immediate Implants Placement in Maxillary Esthetic Zone. (Mohamed sedky)

: Many of studies have been performed to improve osseointegration and bone density around implants by modifying the implant by adding bone graft or substitute material that increase success of implant. Aim: The aim of this study is to evaluate clinically the efficacy of deproteinized bovine bone in maxillary Esthetic zone to promote bone formation and improve outcomes in immediate implant cases. Methodology: 16 immediate implants will be placed in maxillary esthetic zone. That study will be Conducted on 16 hopeless teeth divided equally and randomly into two groups Randomization will be done using www.randomizer.org ., Group 1: 8 hopeless teeth will be replaced by immediate dental implants represent the (control group) where the implants will be placed without bone graft, Group 2: 8 hopeless teeth will be replaced by immediate dental implants represent the (study group) where the implants will be placed with deproteinized bovine bone graft. The implant stability will be assessed clinically using (Ostell) immediate postoperative and after 6 months and Postoperative pain using visual analogue scale (VAS). Pre and Post Operative CBCT Will be taken. Bone density will be assessed Using 3D onDemand Softwear.
