Summary
Dental implants in augmented sinus floors offer a viable solution for resorbed maxillae. Survival rates vary, but the procedure is justified for well-informed patients seeking prosthetic restoration.
Area of Science:
- Oral surgery
- Dental implantology
- Maxillofacial reconstruction
Background:
- Resorbed maxillae present significant challenges for dental implant placement.
- Sinus floor augmentation is a common procedure to address insufficient bone height in the posterior maxilla.
- Evaluating implant survival in these augmented sites is crucial for treatment planning.
Purpose of the Study:
- To investigate the survival rates of dental implants placed in resorbed maxillae, including those augmented via sinus lift procedures.
- To assess the long-term success of implants supporting fixed bridges and overdentures in different edentulous states.
Main Methods:
- Retrospective analysis of patients with dental implants in resorbed maxillae.
- Inclusion of both edentulous and partially edentulous patients.
- Evaluation of patients who underwent sinus floor augmentation procedures.
Main Results:
- Five-year cumulative survival rates for implants in augmented sinus floors ranged from 75.6% to 100%.
- Higher survival rates were observed for fixed bridges in partially edentulous patients (100%).
- Implants under overdentures in severely resorbed edentulous maxillae showed a 75.6% survival rate.
Conclusions:
- Implant placement in augmented sinus floors is a justifiable treatment option for patients with resorbed maxillae.
- Informed patient consent is essential due to potential variations in survival rates.
- Sinus floor augmentation provides a successful prosthetic solution for complex maxillary atrophy.
