A comparative evaluation of immediate dental implant with autogenous versus synthetic guided bone regeneration

Immediate implant is a placement of the implant immediately into fresh extraction socket site after tooth extraction and is considered to be a predictable and acceptable procedure. The present work is designed to evaluate the periodontal condition after immediate implant placement and the success rate of implant with autogenous versus synthetic guided bone regeneration. Twenty adult male patients with an endodontic failure, tooth fracture decayed tooth (hopeless tooth) were included in this study. Patients were divided into 2 groups: One group (I) received immediate implants augmented with autogenous bone graft, and the other (group II) received immediate implants augmented with a synthetic bone graft. The results revealed that there was a significant difference between the groups for pocket depth and clinical attachment level. The difference between the groups was statistically highly significant only at 12 months (P < .01). In addition, there was statistically significant difference between the groups at 9 and 12 months (P < .001). Moreover, there was significant decrease of marginal bone loss in group I compared with group II (P < .01). In addition, there was statistically significant difference between the both groups at 9 and 12 months for bone density ( P < .001). Moreover, there was significant decrease of marginal bone loss in group I compared with group II (P < .01). In conclusion, the immediate dental implant placement with autogenous bone graft showed a significant superiority to synthetic bone graft. In addition, the immediate placement-delayed loaded dental implant remains the procedure of choice for predictable achieving of osseointegration.
