Abstract
Zygomatic implants provide a graftless option for the rehabilitation of patients with severe maxillary atrophy. This case report describes the use of piezoelectric instrumentation for extrasinus implant-site preparation in a 76-year-old woman with severe maxillary atrophy and masticatory impairment. A hybrid maxillary rehabilitation was performed with two zygomatic implants and two anterior axial implants using a minimally invasive ultrasonic protocol; the mandibular arch was rehabilitated separately according to an All-on-4 treatment concept. The maxillary prosthesis was delivered 48 hours after surgery. No postoperative complications were reported at the 1-week review, and the 2-year clinical and radiographic follow-up showed stable implant-supported rehabilitation without procedure-related complications. Within the limits of a single case, piezoelectric implant-site preparation offered controlled osteotomy, good intraoperative visibility, and preservation of adjacent soft tissues. Comparative studies are required before superiority over conventional drilling can be established.
