Bioactive composites for bone regeneration. Review.
Beside auto- and allogeneic bone chips used for filling bone lesions or to enhance of bone regeneration, various types of ceramics, natural and synthetized bone mineral hydroxyapatite and tricalcium phosphate, as well as numerous polymers and co-polymers of alfa-hydroxy acids are widely used. These materials in a pure form demonstrate good osteoconductivity, but very rarely are osteoinductive. ...
متن کاملBioactive ceramic-reinforced composites for bone augmentation.
Biomaterials have been used to repair the human body for millennia, but it is only since the 1970s that man-made composites have been used. Hydroxyapatite (HA)-reinforced polyethylene (PE) is the first of the 'second-generation' biomaterials that have been developed to be bioactive rather than bioinert. The mechanical properties have been characterized using quasi-static, fatigue, creep and fra...
متن کاملBioactive Ceramic-polymer Composites for Bone Replacement
Bone, at the ultra-structural level, is a composite with mechanical properties that can be matched by man-made composites. It serves as the template for developing bone replacement materials. Research on biomaterials analogous to bone was started in the early 1980s by incorporating bioactive particles into biocompatible polymers to produce bone substitutes. Hydroxyapatite reinforced high densit...
متن کاملBioactive Glass Fiber-Reinforced PGS Matrix Composites for Cartilage Regeneration
Poly(glycerol sebacate) (PGS) is an elastomeric polymer which is attracting increasing interest for biomedical applications, including cartilage regeneration. However, its limited mechanical properties and possible negative effects of its degradation byproducts restrict PGS for in vivo application. In this study, a novel PGS-bioactive glass fiber (F18)-reinforced composite was developed and cha...
متن کاملBone regeneration in dentistry using bioactive glass 49S :A review
Background and Aim: The aim of this study was to evaluate the effect of 49S bioactive glass nanoparticles made by sol-gel technique on bone regeneration in dentistry. These glass are especially used as bone repair materials because of their properties such as biodegradability and bioactivity, so they seem to be successful in orthopedic and dental surgery. Material and Methods: Acoording to this...
