History. A material well-known in medical engineering finds its way into the world of dentistry. The PEKK material used for Pekkton® ivory originates from the PAEK (PolyArylEtherKetone) materials family. High- performance polymers have found their way into ortho paedics and traumatology since the 1980s.1 They are used as knee, spinal or craniomaxillofacial implants due to their bone-like behaviour. Since 2011, PEKK has also been used in the dental market. Based on the semi-crystalline, implantable base material, Cendres+Métaux offers Pekkton® ivory exclusively as a framework material for dental...

The PAEK family. From a chemical perspective. PAEK PEKK PEEK High-performance polymers Technical polymers Conventional polymers Crystalline The PEAK family at the top of the performance pyramid The high-performance polymers PEEK and PEKK both be long to the family of polyaryletherketones, referred to in short as PAEK. PAEKs are high-performance thermoplastics which demon strate high strength, stiffness and resistance to hydrolysis over a wide temperature range and are suitable for extreme loads. When processing thermoplastics, only the shape is changed, but not their chemical properties. Furthermore,...

Mechanical properties. Pekkton® ivory – a polymer resembling biological materials. Masticatory effect on the jaw bone. The lower jaw bone in particular is exposed to various tensile and compressive forces. Add to this, the natural torsion due to the comminution of food.3 The use of rigid materials for prosthetic solutions such as zir conium ceramics or metals, limits the natural mobility of the jawbone and transfers the forces to the implants, the den tures or even the bone tissue. This can have a negative effect on the osseointegration of the implants and the physiological movement patterns....

The test methods used may differ. Titanium framework Behaviour of different framework materials under a load of 500 N and an inclination of 30°. Traditionally with hard materials, the stress caused by the masticatory force accumulates selectively. In the case of Pekkton® ivory, the loads are distributed...

Mechanical properties. Shock absorption. Masticatory force-absorbing behaviour An interesting property of the Pekkton® ivory material is the masticatory force-absorbing behaviour. Natural teeth are an chored in the alveolus by Sharpey's fibres and allow mastica tory forces to be absorbed in a natural way. As implants are connected directly to the bone, this dampen ing property is not present. When conventional and hard materials are used for prosthetic solutions, masticatory force peaks can therefore no longer be dampened and can be transferred directly to the peri-implant bone tissue. This can...

Examples of applications. Pekkton® ivory in use. Pekkton® ivory was developed as an alternative, metal-free framework material. The material can be used to fabricate classical crowns and bridges on natural teeth. Due to the masticatory force-absorbing properties of Pekkton® ivory, the material is also frequently used for implant-supported p rostheses. For example, crowns, bridges or individual abut ments bonded to titanium bases can be covered with Pekkton® ivory. The high performance polymer can also be used for remov able dentures. Examples for this are prosthesis bases on construction elements...
