Long-term retrospective studies on the CT-scan, CAD/CAM, one-stage surgery hydroxyapatite-coated subperiosteal...

The subperiosteal implant has long been regarded as the most successful, predictable, and versatile of all implant systems. In some cases, however, anatomic morphology and surgical technique present certain limitations for the subperiosteal procedure. Through CAD/CAM multiplanar diagnostic imaging, not only have we been able to eliminate the first stage of the surgical procedure, but we have expanded the capabilities and versatility of the subperiosteal procedure. In addition, coating the subperiosteal implant frame with hydroxyapatite has allowed the achievement of bony union, thus increasing the long-range prognosis of the individual case.
