In Vitro characterization of low modulus linoleic acid coated strontium-substituted hydroxyapatite containing PMMA bone cement.
Poly (methyl methacrylate) (PMMA) bone cement is widely used in vertebral body augmentation procedures such as vertebroplasty and balloon kyphoplasty. Filling high modulus PMMA increases the modulus of filled verterbra, increasing the risk of fracture in the adjacent vertebra. On the other hand, in porous PMMA bone cements, wear particle generation and deterioration of mechanical performance ar...
متن کاملThree-layered membranes of collagen/hydroxyapatite and chitosan for guided bone regeneration.
The purpose of this study was to design a novel hybrid membrane with optimized properties for guided bone regeneration (GBR). Both the top and bottom layers of the sandwich-structured membrane were composed of collagen containing 20 wt% hydroxyapatite (HA), while the middle layer was made of chitosan. The above three layers were formulated into an integral membrane from their respective slurrie...
متن کاملBioresorbable Collagen Membranes for Guided Bone Regeneration
Localized lack of bone volume in the jaws may be due to congenital, post-traumatic, postsurgical defects or different disease processes. Increasing the bone volume has long been an attractive field of basic and clinical research. The introduction of implant therapy, and the proven relationship between long-term prognosis of dental implants and adequate bone volume at the implant site (Lekholm e...
متن کاملMembranes for the Guided Bone Regeneration
Many kinds of membrane have been used for the guided bone regeneration (GBR) technique. However, most membranes do not fulfill all requirements for the ideal membrane for the GBR technique. Among them, collagen membrane has been most widely used. However, its high price and weak tensile strength in wet condition are limitations for wide clinical application. Synthetic polymers have also been us...
متن کاملAlveolar bone repair with strontium- containing nanostructured carbonated hydroxyapatite
This study aimed to evaluate bone repair in rat dental sockets after implanting nanostructured carbonated hydroxyapatite/sodium alginate (CHA) and nanostructured carbonated hydroxyapatite/sodium alginate containing 5% strontium microspheres (SrCHA) as bone substitute materials. Twenty male Wistar rats were randomly divided into two experimental groups: CHA and SrCHA (n=5/period/group). After on...
