Zygomatic Implant

Zygomatic implants are extra-long implants (typically 30–52mm) that pass through the upper jaw and anchor in the zygomatic bone (cheekbone). They were developed by Professor Brånemark in the 1990s as a solution for patients with severely resorbed upper jaws who would otherwise require extensive bone grafting.

When are they used?

Zygomatic implants are indicated when the maxilla (upper jaw) has lost so much bone volume — typically from severe tooth loss, trauma, or failed dentures — that conventional implant placement is not possible and extensive bone grafting would be too complex, risky, or time-consuming.

Advantages over bone grafting

• No bone graft required — uses existing bone in the cheekbone
• Treatment completed in one stage rather than the two or more stages needed for major grafting
• Immediate loading is usually possible
• Faster overall treatment timeline

Limitations

• Highly advanced surgical procedure — requires specific training and experience
• Higher surgical complexity and longer operative time
• Risk of sinus complications
• Not needed for the majority of implant patients

Zygomatic implants are a remarkable solution for complex cases but are used selectively. Most patients with bone deficiency in the upper jaw can be treated with conventional grafting techniques.
