Eposteal Implant (Subperiosteal)

Also known as a Subperiosteal Implant. This is a metal framework that rests on top of the jawbone but underneath the gum tissue. Posts protrude through the gums to hold the denture.

Why It Matters

These are largely considered outdated or "historical" in modern dentistry. They were used for patients who did not have enough bone height for standard (endosteal) implants. Today, bone grafting and All-on-4 techniques have mostly replaced them.

Clinical Details

• Placement: Requires two surgeries (one to mold the bone, one to place the frame) or advanced CT modeling.
• Risk: Higher rate of infection and rejection compared to endosteal implants.
