Pterygoid implants are a reliable option for rehabilitating patients with an atrophic posterior maxilla, where conventional implants often fail due to poor bone quality and sinus pneumatization. By anchoring into the dense cortical bone of the pterygoid plate, they provide strong stabilization, avoid the need for grafting or sinus lift, reduce treatment time, and allow immediate loading. Studies show high success rates with minimal complications, making them a less invasive and effective alternative for restoring function and esthetics in challenging maxillary cases.
