As a German‑imported implant brand, Meoplant® firmly believes that a good implant starts with the right material. We choose German grade 4 cold‑worked titanium – not because it’s a trend, but because it genuinely addresses the core challenges of long‑term implant performance.
Many people have heard of grade 4 commercially pure titanium and grade 5 titanium, but “grade 4 cold‑worked titanium” may be less familiar. In simple terms, it is an upgraded material derived from grade 4 pure titanium through cold‑working processes such as cold rolling and cold drawing.
This cold‑working step brings a decisive transformation: it retains pure titanium’s excellent biocompatibility while elevating mechanical strength to a level comparable to grade 5 titanium alloys.
The data tell the story: grade 4 cold‑worked titanium can achieve a tensile strength of up to 825 MPa, far exceeding that of ordinary grade 4 pure titanium. This means that implants made from this material can easily withstand the various stresses of daily chewing, without the risk of fracture or breakage.
Pure Titanium, Safe Even for Sensitive Patients
Strength is only one advantage of grade 4 cold‑worked titanium. Even more importantly, its composition is identical to that of grade 4 pure titanium – over 99% pure titanium, with no added aluminium, vanadium, or other alloying elements.
This is critical for dental implants. While grade 5 titanium offers high strength, it contains approximately 6% aluminium and 4% vanadium. Although widely used clinically, for a small number of patients with metal sensitivity, long‑term implantation may raise concerns about the release of aluminium and vanadium ions. Grade 4 cold‑worked titanium, being 100% pure titanium, offers outstanding biocompatibility and effectively reduces the risk of tissue rejection – making it a safer choice for metal‑sensitive patients.
Corrosion Resistance – The True Key to Longevity
The oral environment is moist, with fluctuating pH levels and constant exposure to food debris and bacteria. Over time, ordinary implants are prone to galvanic corrosion at the implant‑abutment connection. Though invisible to the naked eye, this corrosion gradually leads to abutment loosening, bacterial infiltration, and ultimately compromises implant lifespan.
Thanks to the cold‑working process, grade 4 cold‑worked titanium has a denser microstructure and significantly enhanced corrosion resistance. Meoplant’s grade 4 cold‑worked KV‑grade material effectively reduces the risk of galvanic corrosion at the connection interface – it resists rust and degradation, ensuring that the implant stays stable and durable right from the material level.
German Precision Engineering – Maximising the Value of a Superior Material
Excellent material deserves excellent craftsmanship to deliver its full potential. Meoplant® is headquartered in Berlin, Germany, and adheres to German DIN standards throughout the entire process – from raw material sourcing and technology to manufacturing.
On this foundation, we integrate patented MEOBAND® surface treatment, an 11° gold taper, and a hexagon interlocking connection design. These precision engineering elements fully unleash the high strength and corrosion resistance of grade 4 cold‑worked titanium – the material withstands corrosion, the structure locks securely, and the result is a single implant that truly lasts.
Dental implantation is a lifelong investment – the material is not to be compromised. German Meoplant® Implant System with grade 4 cold‑worked titanium delivers the safety of pure titanium, the strength of an alloy, and the precision of German engineering – so that every implant can accompany you for years to come.
