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

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.
