Summary
Comparing conventional instruments with piezoelectric devices for sinus floor elevation, this study found both methods effective for augmenting the atrophic maxilla. The piezoelectric technique offers a viable alternative for maxillary sinus grafting.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Regenerative Medicine
Background:
- Sinus floor augmentation is crucial for posterior maxillary atrophy.
- Transalveolar techniques are established for sinus floor elevation.
- Comparing instrumentation methods is essential for optimizing procedures.
Purpose of the Study:
- To compare conventional hand instruments with piezoelectric devices for maxillary sinus floor elevation.
- To evaluate graft volumes and membrane trauma between techniques.
- To determine the efficacy of each method in augmenting the atrophic maxilla.
Main Methods:
- Cadaveric study involving 17 heads.
- Transcrestal sinus membrane elevation using piezosurgery or conventional instruments.
- Radiopaque material for sinus augmentation simulation.
- Post-operative CT scans for volume determination.
Main Results:
- Mean graft volumes: Summers' technique (0.29 ± 0.18 cm³), Sinus Physiolift® (piezoelectric) technique (0.39 ± 0.32 cm³).
- No statistically significant difference in augmented volume or Schneiderian membrane trauma.
- Both techniques achieved expedient augmentation.
Conclusions:
- Both conventional and piezoelectric techniques yield effective augmentation volumes.
- The piezoelectric technique is a recommended alternative for sinus floor grafting.
- Further research may explore long-term outcomes and clinical applications.
