The Success Rate of Implants Placed in Reconstructed Alveolar Ridges Using Iliac Bone Graft Compared to Non-augmented Jaw

摘要

Aim: This study is aimed to investigate the success rate and clinical outcome of placed implants in reconstructed alveolar ridges using iliac cortico-cancellus bone graft compared to normal non-augmented alveolar ridge. Materials and Methods: In this clinical trial study, 30 patients who were selected and assigned in case and control groups. The case group included patients with severe alveolar bone loss, who needed bone grafting. The control group included patients with sufficient alveolar ridge and no need for bone grafting. The prosthesis was placed on implants after 3 to 8 months. Plaque index, bleeding, pocket depth, mobility, pain, pus secretion and bone loss were evaluated after 24 month. Data were analyzed by SPSS 13. P -value less than 0.05 was considered as significant. Results: Out of 30 patients, two were excluded due to their requirements. Totally 97 implants were placed in patients, which included 52 implants in control group and 45 implants in case group. All of the implants were successfully osseointegrated and loaded. There was no significant difference between the success of inserted implants between both groups ( P =0.05). The mesial and distal bone losses were significantly more in patients without iliac bone graft ( P =0.05). There was no statistically significant difference between measured outcomes including plaque, bleeding, pocket depth, mobility, pain, and pus secretion ( P =0.05). Conclusion: Inserted implant in free non-vascularized iliac bone graft has high rate of success comapred to non-augmented alveolar ridges and has shown to be a reliable method for reconstruction of severe atrophic jaws.
