PORESORB-TCP is a bioactive, resorbable, inorganic bone regeneration material. It creates stable contact with bone and prevents the formation of a soft tissue interlayer. PORESORB-TCP has osseoconductive and osseoinductive properties which significantly increase the treatment efficiency. As a phase-pure β-tricalcium phosphate matrix with an interconnecting porosity it can be completely resorbed and gradually replaced by newly formed bone. PORESORB-TCP as a fully synthetic material avoids any potential immunological or infection risks arising from materials of biological origin.
