Immediate Implant Using "Nanobone" Versus "Autogenous Bone" for Treatment of Patients With Unrestorable Single Tooth.

Immediate implant placement with Nanobone will offers great advantages for patients with unrestorable tooth as regards decrease surgical time, Post-Operative pain and marginal bone loss, increase implant stability compared to immediate implant with autogenous bone graft.Study is to be conducted in the oral medicine and periodontology department - Cairo University, Egypt. Post graduate clinic 1st floor old section. Unit Sirona2with LED light. Digital radiographic imaging will be carried out in the Oral Radiology Department, Faculty of Oral and Dental Medicine, Cairo University using digital intra-oral x-ray machine as well as CBCT imaging. Using CBCT determine the size and length of fixture will be used. After a traumatic extraction, using drills to prepare the socket for the implant. Standard drilling procedures are performed according to the manufacturer's instructions implant direct. The axis of the implant must correspond to the incisal edges of the adjacent teeth or be slightly palatal to this landmark. Place the exact size determined previously by CBCT. In the esthetic zone, the implant head should be a minimum of 3 mm apical to an imaginary line connecting the cemento-enamel junctions of the adjacent teeth and apical to the interproximal and crestal bone.The gap between the facial aspect of the implant and the buccal wall was filled with NanoBone.The flap will be scored and sutured in place without tension. While in the control group, Harvesting of the autogenous bone graft will be done. This group will be subjected to the same implant placement protocol as the study group. Postoperative care include; A dressing will be applied to the extraoral wound for 24 hours postoperatively in the control group, Patients will maintain on oral antibiotics (Amoxicillin/Clavulanic acid 1gm q12h) and analgesics (cataflam 50 mg q8h) for 5 more days. Chlorohexidine mouth wash will be prescribed for 2 more weeks.
