Subperiosteal Implants: For Extreme Maxillary and Mandibular Atrophy

While Endosteal Implants (those placed into the bone) are the current industry standard, Subperiosteal Implants serve as a critical clinical solution for patients with extreme bone resorption who cannot undergo traditional bone grafting.

Unlike standard fixtures, a subperiosteal implant consists of a custom-designed metal framework that sits on top of the jawbone but under the gum tissue.

How Subperiosteal Implants Work

Modern subperiosteal systems are now manufactured using 3D Laser Sintering and CAD/CAM technology based on the patient's 3D CBCT imaging. This ensures a perfect custom fit to the unique contours of the patient's remaining bone structure.

Key Clinical Advantages:

• No Bone Grafting: Ideal for patients with "severely atrophic" ridges.
• Single-Stage Procedure: Often eliminates the Sinus Lift or Bone Grafting phases.
• Immediate Function: The framework is designed to provide immediate stability for Fixed Hybrid Restorations.

The Scientific Evolution

In the mid-20th century, subperiosteal implants had mixed success rates. However, the advent of biocompatible materials like Medical-Grade Titanium and high-precision digital scanning has revitalized this procedure in advanced oral surgery centers.

Potential Risks and Limitations:

• Surgical Complexity: Requires an highly experienced Oral Surgeon.
• Long-Term Remodeling: Clinical success depends heavily on the quality of the overlying soft tissue (Gums).
• Maintenance: Requires strict Implant Cleaning Protocols to prevent infection (Peri-Implantitis).

Patient Candidacy

Subperiosteal implants are generally recommended for patients who:

1. Have horizontal and vertical bone loss that cannot be addressed by Zygomatic Implants.
2. Have failed traditional endosteal implant attempts.
3. Require full-mouth reconstruction but wish to avoid multiple bone augmentation surgeries.
