Optimization of Bone Scaffold Engineering for Load Bearing Applications
T his review highlights concepts that are required for successful generation of bone scaffolds to be used in load bearing applications. Through a discussion of the bone hierarchical levels, scaffold fabrication methods, and bone modeling response, a paradigm shift in the basic set of rules for scaffold generation is illustrated. Following these suggested guidelines may lead to the design of sca...
متن کاملNano-mechanics of bone and bioactive bone cement interfaces in a load-bearing model.
Many bioactive bone cements were developed for total hip replacement and found to bond with bone directly. However, the mechanical properties at the bone/bone cement interface under load bearing are not fully understood. In this study, a bioactive bone cement, which consists of strontium-containing hydroxyapatite (Sr-HA) powder and bisphenol-alpha-glycidyl dimethacrylate (Bis-GMA)-based resin, ...
متن کاملPorous Surface Modified Bioactive Bone Cement for Enhanced Bone Bonding
BACKGROUND Polymethylmethacrylate bone cement cannot provide an adhesive chemical bonding to form a stable cement-bone interface. Bioactive bone cements show bone bonding ability, but their clinical application is limited because bone resorption is observed after implantation. Porous polymethylmethacrylate can be achieved with the addition of carboxymethylcellulose, alginate and gelatin micropa...
متن کاملBiphasic calcium phosphate nanocomposite porous scaffolds for load-bearing bone tissue engineering.
A novel biodegradable nanocomposite porous scaffold comprising a beta-tricalcium phosphate (beta-TCP) matrix and hydroxyl apatite (HA) nanofibers was developed and studied for load-bearing bone tissue engineering. HA nanofibers were prepared with a biomimetic precipitation method. The composite scaffolds were fabricated by a method combining the gel casting and polymer sponge techniques. The ro...
متن کاملDevelopment of Composite Scaffolds for Load-Bearing Segmental Bone Defects
The need for a suitable tissue-engineered scaffold that can be used to heal load-bearing segmental bone defects (SBDs) is both immediate and increasing. During the past 30 years, various ceramic and polymer scaffolds have been investigated for this application. More recently, while composite scaffolds built using a combination of ceramics and polymeric materials are being investigated in a grea...
