Zygomatic implants are a specialized type of dental implant used for patients who have severe bone loss in the upper jaw. Unlike traditional dental implants that are anchored in the jawbone, zygomatic implants are anchored in the zygomatic bone, or cheekbone. This makes them a viable option for patients who lack sufficient bone in the upper jaw for conventional implants. In this comprehensive guide, we will explore the pros and cons of zygomatic implants, their procedure, aftercare, and everything else you need to know to make an informed decision.

What Are Zygomatic Implants?

Zygomatic implants are longer than traditional dental implants and are anchored in the zygomatic bone rather than the maxilla (upper jawbone). This allows them to provide a stable and secure foundation for dental prosthetics in patients with significant bone loss in the upper jaw. The procedure is more complex and typically performed by specialists with experience in this type of implant placement.

Anatomy of Zygomatic Implants

Length: Zygomatic implants are significantly longer than traditional implants, often ranging from 30 to 52.5 millimeters.
Material: Typically made from titanium, known for its biocompatibility and strength.
Placement: Anchored in the zygomatic bone, which is denser and offers more support than the maxilla in patients with severe bone loss.

Procedure Overview

The placement of zygomatic implants involves several steps:

Consultation and Planning: Detailed evaluation and planning using imaging technologies such as CT scans to assess bone structure and plan the placement.
Surgery: Performed under general or local anesthesia, the implants are placed through the maxillary sinus to anchor in the zygomatic bone.
Restoration: After osseointegration (the process where the implant fuses with the bone), prosthetic teeth are attached to the implants.

Pros of Zygomatic Implants

1. Suitable for Severe Bone Loss

Benefit: Zygomatic implants are an excellent option for patients who have severe bone loss in the upper jaw and are not candidates for traditional implants.

Explanation: Since they are anchored in the zygomatic bone, which typically has sufficient density, they provide a stable foundation without the need for bone grafting.
