Solid-Phase Petri-Pterygoid Intra-Oral Retractor (23cm) for Advanced Maxillary Access
The Petri-Pterygoid Intra-Oral Retractor 23cm is a cornerstone of the orthognathic surgical tray, specifically engineered for the stable displacement of soft tissue at the posterior maxillary border. Functioning as a high-performance pterygoid anchor, this model features a distinctively curved blade that prevents tissue slippage while protecting the descending palatine neurovascular bundle. Adas Instruments ensures that each Petri-Pterygoid is balanced for high-accuracy maneuvers, allowing the surgical assistant to maintain a steady field of view during Le Fort osteotomies. By utilizing the Petri-Pterygoid , surgeons benefit from a deep-field shield that protects the soft palate during bone mobilization. We ship USA, Europe & worldwide via DHL, FedEx, and UPS to deliver German steel instruments that surgeons trust for their anatomical efficiency and structural resilience.
