The pterygoid advantage

Stable posterior support in atrophic maxilla.

The Surcam® Pterygoid Dental Implant is designed for placement into the pterygoid process of the sphenoid bone, providing strong posterior anchorage when conventional implants cannot be placed due to severe maxillary bone loss.

By engaging dense cortical bone in the pterygoid region, this implant allows clinicians to restore posterior support without sinus augmentation procedures, simplifying treatment for advanced atrophy cases.

The design is optimized to match the anatomy of the posterior maxilla, enabling secure placement and long-term prosthetic stability.

Design

Key features and clinical benefits.

01
Internal hexagon – 2.43 mm
Precision internal connection ensures stable prosthetic seating and compatibility with Surcam restorative components.
02
Soft tissue neck (2 mm / 4 mm)
Smooth cervical neck available in 2 mm or 4 mm with TiN/PVD coating to support soft tissue health and reduce bacterial adhesion.
03
Conical threads & core
Optimized macro-design improves insertion control and enhances engagement in dense cortical bone.
04
SLA surface treatment
Sand-blasted and acid-etched surface increases bone-to-implant contact and supports reliable osseointegration.
05
Coarse thread geometry
Aggressive thread profile improves fixation and stability during placement in the posterior maxilla.
06
Anchoring apex
Narrow apical design facilitates guided insertion and stable anchorage within the pterygoid region.

From the clinic

The Pterygoid implant gives me the posterior support I need in severely atrophic maxilla cases. Engaging the pterygoid region provides excellent stability, allowing full-arch restorations without sinus grafting. Placement feels controlled, and long implants seat securely. It’s an extremely valuable solution for advanced cases.
