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.
