What Are Pterygoid Implants?
If you have been told you do not have enough bone in the upper back jaw for implants, pterygoid implants may be an option. Here is an introduction.
Pterygoid implants are specialized dental implants that anchor into the pterygoid bone β a dense bone located at the back of the upper jaw, near the base of the skull. They are designed for patients with significant bone loss in the posterior (back) upper jaw.
- How they work:
- The implant is placed at an angle through the upper jaw into the pterygoid plate
- This area has dense bone that provides excellent stability
- Typically 20β30 mm in length
- Why they are used:
- To avoid sinus lifts or bone grafting in the upper back jaw
- To provide support for a full arch of teeth when there is insufficient bone for regular implants in the molar area
- To create a long, stable foundation without entering the sinus cavity
- Who they are for:
- Patients with severe bone loss in the upper back jaw (molar area)
- Patients who want to avoid sinus lift surgery
- Patients with failed previous implants in the posterior maxilla
- Patients undergoing full arch rehabilitation
