23 Jul BIOACTIVE COMPOSITE FOR BONE REPAIR
Abstract
The present invention has applications in the fields of medicine, pharmaceutics and biological tissue engineering. The invention relates to the development of a bioactive composite for bone repair with a polymer matrix composed of a polysaccharide, and strengthened with calcium derivatives, such as calcium hydroxide, hydroxylapatite, or calcium phosphate, in order to produce bioactive composites specific to bone tissue. The strengthening material is used at different concentrations relative to the matrix in order to produce mouldable composites machined into fracture-resistant screws, pins and plates with various elastic deformation values suitable for specific uses in bone fixation, bone repair, bone induction and bone conduction for the treatment of lesions of bone tissue accompanied by loss of substance, including critical defects.
