Pre- and Post-Rehabilitation Tomographic Superimposition of Full Arch Cases, Obtaining the Drop Values and How to Get...

Rehabilitating severely atrophic maxillae, particularly when bone loss and sinus pathologies preclude conventional dental implants, is a complex challenge. Techniques such as all-on-four offer solutions for some patients, but severe resorption may necessitate zygomatic implants. Guided surgery, aided by digital tools, improves implant accuracy and reduces complications. These techniques help avoid sinus or orbital damage and ensure better prosthetic outcomes. A review of clinical studies highlights the precision of bone-supported guides for implant placement and underscores the importance of surgical expertise in reducing complications.
