Summary
Zygomatic implants offer a viable alternative for severe maxillary resorption, showing high prosthetic success and implant survival rates over five years. This study confirms their acceptable clinical outcome when combined with conventional implants.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Prosthodontics
Background:
- Extreme maxillary resorption presents challenges for oral rehabilitation.
- Zygomatic implants offer a non-grafting solution for such cases.
- Long-term prognosis data for zygomatic implants is limited.
Purpose of the Study:
- To evaluate the 5-year prosthetic rehabilitation success rate.
- To assess the survival rates of zygomatic and conventional implants.
- To analyze complications in patients with atrophic maxillae.
Main Methods:
- Retrospective study of 24 patients with atrophic maxillae.
- Placement of 45 zygomatic and 109 conventional implants.
- Follow-up over 5 years, assessing prosthetic and implant survival.
Main Results:
- 95.8% prosthetic rehabilitation success rate after 5 years.
- Zygomatic implant survival rate of 97.4% after 5 years.
- Conventional implant survival rate of 89.9% after 5 years.
Conclusions:
- Zygomatic implants combined with conventional implants show acceptable 5-year clinical outcomes.
- This approach provides a reliable option for oral rehabilitation in atrophic maxillae.
- Further long-term studies are warranted.
