Summary
This study shows that using venous blood to support the sinus membrane during dental implant placement leads to significant bone formation. This technique is a safe alternative for maxillary sinus augmentation.
Area of Science:
- Dental Implantology
- Oral Surgery
- Regenerative Medicine
Background:
- Maxillary sinus augmentation is a common procedure to increase bone volume for dental implants.
- Traditional graft materials have limitations, prompting research into alternative methods.
Purpose of the Study:
- To assess bone formation when a sinus membrane is tented with implants and supported by venous blood.
- To evaluate the efficacy of peripheral venous blood as a graft material in sinus augmentation.
Main Methods:
- Sinus floor elevation using a lateral window approach in 14 patients (17 augmentations).
- Simultaneous placement of dental implants with tenting of the sinus membrane using autologous peripheral venous blood.
- Piezoelectric bone window creation and repositioning for closure.
Main Results:
- Histomorphometric analysis revealed 38.70% vital bone formation.
- Radiographic and histologic evaluation confirmed new bone consolidation after an average of 6.8 months.
- An overall implant survival rate of 93.5% was achieved, with failures linked to poor initial stability.
Conclusions:
- Simultaneous dental implant placement and sinus augmentation using venous blood is a viable and safe procedure.
- Peripheral venous blood serves as an effective graft material, promoting bone regeneration in the maxillary sinus.
