The present study was designed to compare clinically and radiographicaly between immediate dental implant augmented with biphasic calcium phosphate (BCP) and it augmented with BCP coated with polylactide -co- glycolide (PLGA).This study was carried out on twenty adult male patients ,which were divided into two groups (group I included ten patients received immediate implant augmented with BCP ,while group II included ten patients were received immediate implants augmented with biphasic BCP coated with PLGA). Patients were evaluated clinically and radiographically to assess Gingival Index (GI) ,Probing pocket depth (PPD) , Marginal bone level (MBL), and Bone density measurement (BD) parameters at 3, 6, 9&12 months. Statistical analysis of GI and MBL results showed no significant difference in both groups at the different intervals while PPD results showed significant difference between both groups only at 9 and 12 months. On the same side, BD measurements showed statistical difference between groups at 3 month and highly statistical significant difference at 6, 9 and 12 months. The present study concluded that BCP coated with PLGA was significantly superior in comparison with BCP in augmentation of immediate dental implant
