| Abstract | ||||
| INTRODUCTION: Replacing a single tooth by the use of immediate implant can eliminate the need for preparation of a sound tooth to use it as an abutment. The drawbacks of using autogenous bone grafts have led to producing a large number of alternative bone substitute materials to fill in the jumping gap which can encourage bone formation and affect implant stability and crestal bone loss depending on different prespectives as Nanocrystalline hydroxyapatite particles and xenografts. Objectives: The aim of this study is to evaluate clinically and radiographically the quality of osseointegration for both Nanocrystalline hydroxyapatite particles and xenograft around immediately placed and loaded dental implants in the esthetic zone by measuring implant stability and marginal bone loss. Materials and Methods: This study is conducted on sixteen patients diagnosed with unrestorable anterior single tooth indicated for extraction and immediate implant placement. Nanocrystalline hydroxyapatite particles was used around the implant in group A while xenograft was used in group B. Follow up was done immediately postoperative and after four and seven months. Results: Insignificant statistical difference was reported in Implant stability, and crestal bone loss during the follow up period when comparing both groups during the fourth and the seventh months follow up period. Conclusion: Within the limitations of this study. Even though Nanocrystallne hydroxyapatite particles was placed in the jumping gap, it did not prevent bone loss following tooth extraction and immediate implant installation same as xenograft bone group. | ||||
