Enhancement of Biocompatibility and Degradation Properties in a Poly-L-Lactide/ Hydroxyapatite Blend
نویسنده
چکیده
The use of porous blocks is limited, however, because hydroxyapatite has only modest tensile strength and a low fracture toughness, leaving it susceptible to fracture or fragmentation if subjected to mechanical loading. Incorporating hydroxyapatite granules into a biocompatible polymeric matrix produces a more robust material. Judicious selection of the loading level of the HA allows for a highly biocompatible device with mechanical properties appropriate to the clinical need.

Synthesis and Thermal Properties of Novel Biodegradable ABCBA Pentablock Copolymers from Poly (Ethylene glycol), L-Lactide and p-Dioxanone
In this work, new biodegradable ABCBA type pentablock copolymers with different mole ratio of L-lactide and PPDO-b-PEG-b-PPDO triblock copolymer were synthesized and characterized. In the first step, PPDO-b-PEG-b-PPDO triblock copolymer was synthesized via a ring-opening polymerization of P-DiOxanone (PDO) monomer with Poly (Ethylene Glycol) (P...

The essence of tissue engineering is the fabrication of autologous cells or induced stem cells in naturally derived or synthetic scaffolds to form specific tissues. Polymer is thought as an appealing source of cell-seeded scaffold owing to the diversity of its physicochemical property and can be electrospun into nano-size to mimic natural structure. Poly (L-lactic acid) (PLLA) and poly (ε-capro...

Biomaterials based on the polymers of lactic acid and glycolic acid and their copolymers are used or studied extensively as implantable devices for drug delivery, tissue engineering and other biomedical applications. Although these polymers have shown good biocompatibility, concerns have been raised regarding their acidic degradation products, which have important implications for long-term imp...
متن کاملTissue Response to Citric Acid-Based Micro-/Nanocomposites
INTRODUCTION: There is significant demand for orthopaedic implants that are both bioactive and exhibit material properties that are compatible to those of native and healthy tissue [1]. Synthetic materials play an important role in bone repair and bone replacement. In the case of poly (L-lactide) (PLLA), one of the main problems is slow degradation, which further spark tissue loss due to revisi...

Abstracts: The aim of the study was to evaluate the biocompatibility and bioactivity of two new prototype implants for bone tissue regeneration made from biodegradable fibrous materials. The first is a newly developed poly(l-lactide-co-glycolide), (PLGA), and the second is a blend of PLGA with synthetic poly([R,S]-3-hydroxybutyrate) (PLGA/PHB). The implant prototypes comprise PLGA or PLGA/PHB n...
