Summary
Porcine xenografts and autologous bone grafts show comparable results for maxillary sinus augmentation, offering high dental implant survival rates and low bone loss. Both are excellent options for atrophic maxillae rehabilitation.
Area of Science:
- Oral and Maxillofacial Surgery
- Periodontology
- Regenerative Dentistry
Background:
- Atrophic maxillae pose challenges for dental implant placement.
- Maxillary sinus augmentation is a common procedure to address bone deficiency.
- Graft material selection is crucial for successful outcomes.
Purpose of the Study:
- To compare autologous bone versus porcine xenograft for maxillary sinus augmentation.
- To evaluate marginal bone loss, implant survival, and complications.
- To assess the efficacy of these materials in oral rehabilitation.
Main Methods:
- Randomized controlled clinical trial with a split-mouth design.
- 12 adult patients underwent bilateral maxillary sinus floor augmentation.
- Autologous bone (control) and porcine xenograft (test) were used.
- 39 dental implants were placed and followed for 12 months.
Main Results:
- High implant survival rates: 100% for autologous bone, 95% for porcine xenograft.
- Low and similar marginal bone loss in both groups.
- No major surgical complications; one patient experienced prosthetic complications.
Conclusions:
- Both autologous bone and porcine xenograft are effective for maxillary sinus augmentation.
- These materials support high dental implant survival and minimal bone loss.
- Maxillary sinus augmentation is a viable procedure for atrophic maxillae restoration.
