Sabilex has developed Biostrong, a high-performance polymer made from PEEK, which has unique properties. The sharp increase in allergies, metal intolerance symptoms and sensitivity to galvanic currents, have led to a change in thinking when it comes to selecting and using dental materials. Metal-free restorations are increasingly requested. PEEK is a widely used material in industry that has also found its way into biomedicine. It was patented in 1981 as an implant material and approved by the FDA in 1999, mainly in the fields of orthopedics and traumatology, but also in neurosurgery. In dentistry, it is effectively used for implants, removable partials, telescopic structures, crowns, bridges and hybrid dentures. PEEK-based biomaterials are a generation of bioactive materials, which can work alone or in combination with other biomaterials to enhance their properties. Characteristics: -High performance semicrystalline polymer, based on PEEK -Comfortable and light for the patient. -It’s hard and resistant to abrasion, and has a low coefficient of friction. -It has exceptional resistance to fatigue, wear and impact. -Its hardness and strength is comparable to stainless steel. -Resistant to the attack of chemical products. -Maintains its physical and chemical integrity. -It does not present any problem to X-rays and MRIs. -Biocompatible material resistant to the formation of bacterial plaque. - Available in cream or white color. Does not "darken" the gums. - Coverable with conventional or ceromer composite. - Easy to polish. -Currently, it is considered the most biocompatible and least toxic material for the oral cavity. -Maintains its properties when subjected to different temperatures. -PEEK is FDA approved. Uses and applications For the production of crowns, bridges, attachments, bars on implants, telescopic structures and more. • It can be covered with composites, ceromers and other materials to achieve optimal aesthetics.
