A Legacy of German Metallurgy: The Structural Strength Behind Oucass Implant

MUNICH - April 26, 2026 - PRLog -- I. Zapp: Over 300 Years of Industrial Excellence

The core raw materials for Oucass are sourced from Zapp, a world-renowned manufacturer of precision metals based in Germany.

A Storied Heritage: Founded in 1701 by Hermann Zapp, the company began as a water-powered forge and has been led by the Zapp family for over 325 years.

A Pioneer in Precision: As a global leader in high-precision semi-finished metal products, Zapp is known for pushing the boundaries of material technology—from the refined steel of the Industrial Revolution to the advanced alloys used in modern aerospace and medical sectors.

Medical Grade Excellence: As a top-tier supplier of medical titanium, Zapp provides materials that offer not only exceptional biocompatibility but also meet the most stringent physical performance standards.

Pure Pedigree: Every Oucass, Zuga, and Pugart implant is crafted from original Grade 4 cold-rolled pure titanium supplied directly by Zapp, ensuring "German Precision" is baked into the product from the very start.

II. Grade 4 Cold-Rolled Titanium: Strength Beyond the Standard

In clinical consultations, "pure titanium" is often mentioned, but the manufacturing process determines its true resilience.

The Limitations of Standard Titanium: Without specialized reinforcement, standard Grade 4 titanium typically has a tensile strength of around 550MPa. While sufficient for a general diet, it may struggle under the extreme forces required for harder foods.

The Cold-Rolling Advantage: Oucass utilizes a cold-rolling process where metal is compressed under high pressure at room temperature. This compacts the internal crystalline structure—much like pressing loose wood into a high-density board—to significantly enhance fracture resistance.

Exceptional Performance: Thanks to Zapp's patented processing, the cold-rolled titanium used in Oucass achieves a measured tensile strength of 872MPa—nearly a 60% increase over the industry baseline. This high-strength foundation is a shared feature across the entire premium line, including Zuga and Pugart.

III. 5 Million Fatigue Cycles: A 10-Year "Chewing Marathon"

Static data is important, but the oral environment is a dynamic, long-term challenge. To prove the reliability of this strength, Oucass undergoes extreme endurance testing.

Simulating Real Life: In the laboratory, Oucass implants are subjected to 5 million cycles of stress testing. This isn't just simple pressure; it simulates the high-frequency chewing an average person performs over approximately 10 years.

Proven Durability: Test reports confirm that even after millions of continuous impacts, the Oucass implant structure remains perfectly intact, showing zero signs of cracking or deformation.

By combining heritage materials with a peak strength of 872MPa and rigorous fatigue validation, Oucass has established a comprehensive safety system for patients. Strength is more than just a technical specification—it is a guarantee of quality of life.
