PTERYGOID DENTAL implants are a specialized type of dental implant used primarily for patients with significant bone loss in the upper jaw (maxilla), particularly in the posterior region, where traditional implants may not be feasible due to insufficient bone volume or proximity to the maxillary sinus. These implants are anchored in the pterygoid plate of the sphenoid bone, a dense and stable structure at the back of the upper jaw, offering a reliable alternative to bone grafting or sinus lift procedures.
# # # Key Features of Pterygoid Implants
- Placement and Design: Pterygoid implants are longer than conventional implants (typically 15–20 mm) and are inserted at a 45–60° angle into the pterygoid plate, often through the maxillary tuberosity. This positioning bypasses the need for bone augmentation and avoids the maxillary sinus.
- Indications: They are ideal for patients with atrophic maxilla (severe bone loss), partial or complete edentulism, or those seeking to avoid distal cantilevers in prosthetic restorations.
- Advantages:
- Eliminates the need for invasive procedures like sinus lifts or bone grafts, reducing treatment time and morbidity.
- High success rate (approximately 90.7–95% or higher), comparable to traditional implants, with minimal complications.
- Provides stable anchorage in dense bone, enhancing prosthetic stability and functionality.
- Suitable for immediate loading in some cases, allowing faster restoration.
CBCT imaging is required for detailed planing by experienced dental surgeons.
