Piezosurgery, advantages of ultrasound surgery in zygomatic implantology: a case report

Zygomatic implantology represents a consolidated solution for the rehabilitation of patients suffering from severe maxillary atrophy, offering a valid alternative to traditional bone grafting techniques. This technique, first introduced by Professor Branemark in 1998, is based on the anchorage of dental implants in the zygomatic bone, an anatomical structure characterized by high density and resistance to resorption. Unlike the maxilla, the zygomatic bone does not suffer the negative consequences of age, oral cavity pathologies, or tooth loss, ensuring high primary stability for the implants. In recent years, zygomatic implantology has evolved significantly, transitioning from transsinus techniques, which traversed the maxillary sinus, to juxta-sinus techniques, which minimize maxillary sinus involvement and reduce the risk of complications. In this context, piezosurgery, an innovative technique that uses ultrasonic micro-vibrations for bone cutting, is a promising option for zygomatic implantology, potentially improving clinical outcomes and patient comfort. This abstract analyzes the benefits of piezosurgery in zygomatic implantology, highlighting the advantages of precision, minimal invasiveness, and osseointegration. The case presented concerns a 76-year-old female patient with severe upper maxillary atrophy. A Zygoma Hybrid was successfully performed by inserting two zygomatic and two axial implants using the "Minimally Invasive Technique.”
