Introduction: Today, modern surgical and regenerative techniques with implant immediately placed into the prepared socket, predictable gap repair with bone substitutes and soft tissue grafts, have helped to eliminate concerns about bone deficiencies and allowed implant placement according to prosthodontic needs. Materials and Methods: The present in vivo study was designed to evaluate and compare the implant healing after immediate implant placement with or without bone graft and implant healing after delayed implant placement with or without bone graft. Crestal bone levels were compared in both the groups at preoperatively and postoperatively on immediate postoperatively, at 3rd month, and at 6th month. Results: Immediate implant group has more crestal bone level reduction at 3rd and 6th months as compared to the delayed implant group. Immediate implant with bone graft group has insignificant crestal bone level reduction at 3rd and 6th months as compared to immediate implant without bone graft group. Delayed implant with bone graft group has insignificant crestal bone level reduction at 3rd and 6th months as compared to delayed implant without bone graft group. Conclusion: It was concluded from this study that clinical and radiographical bone healing in the delayed implant group with or without bone graft (Group Y) appears to be better than the immediate dental implant group with or without bone graft (Group X).
