Abstract

High-performance polymers (HPP) is a material based on PEEK (poly ether ether ketone) or PEKK (poly ether ketone ketone), which has already been successfully used in operations carried out on humans for many years. The material developed to meet the requirements of dental prosthetics, whose predecessors are being used successfully in human medicine for more than 30 years as spinal intermediate bodies, knuckle joints and hip joint prosthetics, heart valve replacements, so that their bio-compatibility and mechanical properties are already tried and tested. High-performance polymers are greater interest due to a demand for products with optimal physical and aesthetic properties. The material has high flexural and compressive strength. These qualities, coupled with a low modulus of elasticity and therefore low brittleness, ensure the material delivers permanent elasticity. High-performance polymers a measurable resistance of 600 MPs, which clearly shows that this material has got characteristic features that provide more security. Unlike the materials used so far for skeleton restorations, the elastic characteristics of HPP are adaptable to the bone. These high-performance polymers have high long-term stability and low water retention. HPP offers three different options of processing: HPP as milling blank with special cutter for the manufacture of prosthetic fittings in the common CAD/CAM processes. Processing of HPP by means of a pressing procedure, through the for 2 press system, a specially developed vacuum pressing device. Third option is 3d printing on polymer material. The white colour ensures that no dark shadows show through the gingiva. Opaques are therefore not required any more. The innovative material HPP offers new possibilities of fitting patients with fixed and removable high-value dental prosthetics on implants or natural teeth - from individual abutments to telescoping prosthetics, and is ideal framework material for composite veneers for patients with bruxism who require a restoration. Keywords: HPP polymer, dental prosthetic, thermoplastic resin, biologically stable, composite materials, nature-adapted, physical and chemical properties.
