ABSTRACT
Objective: The Aim Of This Study Was To Evaluate And Compare Immediate And Immediate - Delayed Implants In Replacement Of Hopeless Premolars In Aggressive Periodontitis Patients. Subjects And Method: Seven Patients Were Selected Suffering From Generalized Aggressive Periodontitis With Hopless Premolars Bilaterally. They Were Prepared For Extraction Then Sites Divided Into Two Groups: Group A (immediate Implant Placement) To Which Implants Were Placed At Time Of Extractions And Group B (immediate-delayed Implant Placement) Where Extractions Were Done Before Surgery By Six Weeks. They Were Evaluated Clinically At 6 And 9 Months And Radiographically At Baseline, 3, 6 And 9 Months.

Results: There Were No Significant Differences Clinically Between Both Groups While Radiologically There Were Significant Differences Only At 9 Months Where Group B Was Higher In Bone Density. Conclusion: Osseointegrated Implants Can Be Used For Rehabilitation Of Subjects Suffering From Generalized Aggressive Periodontitis (GAgP) Successfully. Immediate-delayed Placement Is Better In Bone Density. More Researches Are Needed.
