Long-term Retrospective Study of Implants Placed after Sinus Floor Augmentation with Fresh-frozen homologous block

چکیده
AIM The aim of this study was to analyze and follow-up implants placed in the posterior maxillary regions previously grafted with homologous bone. MATERIALS AND METHODS Forty-one grafts with homologous bone blocks were performed in maxillary sinuses, and 121 implants were placed in premolar and molar regions approximately 6 months after the grafts. Patients were followed up for periods varying from 12 to 124 months after rehabilitation. RESULTS The results showed two implant failures, for a 98.3% success rate during the follow-up period. DISCUSSION The implants placed had an average torque of 40 N-cm, regardless of the, design, diameter, and length of the implants used. CONCLUSION After following up on the implants placed in this study, we concluded that those placed in regions of the maxillary sinuses previously grafted with homologous bone blocks had high long-term success rates and met the functional masticatory requirements.

PURPOSE The aim of the present study was to evaluate retrospectively both the results of using a mixture of bovine hydroxyapatite (BHA) and fibrin glue as the only grafting material in the floor of the maxillary sinus and the outcome of nonsubmerged implants placed later. MATERIALS AND METHODS A total of 50 consecutive patients (71 maxillary sinuses) were augmented with a mixture of BHA and f...

Background: Reconstruction of severely resorbed jaws requires different surgical procedures to restore the correct bone morphology. These procedures often involve the use of bone substitutes or the harvesting of autologous bone from a donor site. Autologous bone is still regarded as the “gold standard” for augmentation procedures because of its osteogenic potential, but this graft has limited a...

BACKGROUND The long-term stability of maxillary sinus floor augmentation with β-TCP remains largely unknown. We report the long-term assessment of volumetric changes in maxillary sinus floor augmentation with β-TCP by cone-beam computed tomography (CBCT). METHODS The subjects included 30 patients who underwent maxillary sinus floor augmentation using β-TCP and 58 implant placement for unilate...
