Zygomatic Dental Implants

Clinical Concept & Indications

When teeth have been missing for decades, or following severe periodontal disease or trauma, the alveolar bone in the upper jaw (maxilla) can resorb to thin, paper-like dimensions. In such extreme presentations, standard implants cannot achieve mechanical stability, and conventional bone grafting or sinus lifts may carry high failure risks or take over a year to heal.

Zygomatic implants bypass the deficient maxilla by utilizing extended-length fixtures (typically 30 mm to 52.5 mm) anchored into the dense cortical bone of the zygoma (cheekbone), which typically exhibits high structural stability. Where primary insertion stability is achieved, this protocol may support fixed provisional restoration without extensive prior bone grafting.

Candidate Indications

• Severe maxillary bone atrophy (Class V and VI Cawood and Howell classifications)
• Previous failed sinus lift procedures or bone graft complications
• Desire for graftless rehabilitation with immediate provisional loading
• Maxillectomy or oncological surgical defects requiring prosthetic reconstruction
