When bones in bodies are damaged due to injury or illness sometimes, they can berepaired and replaced by nature bones or biomaterials. However, natural bones caninduce infection problems and antigenic reaction. It has attracted great attentions fromresearchers to focus on the biomimetic materials that imitate the structure andcomposition of natural bone. Natural bone is a [...]
The research on bone tissue engineering materials which are used for replacing damaged tissues has extensive implications since the bone tissue which is lost or damaged as a result of injury, infection and ageing becomes increasingly serious. Due to the self-assembly and biomineralization in the long term evolution, natural biomaterials become a kind of material [...]
In recent years, bone tissue engineering material has been becoming animportant choice of bone repair material for many of its merits. Ideal bone repairmaterials should be of good biocompatibility and high bioactivity. Besides, theirmechanical properties should be equivalent to natural bone. Single organic polymermaterial or inorganic ceramic material is difficult to meet the requirements forbiological [...]
Hydroxyapatite (HAP) is the main inorganic component of human and animal teeth, bones, bone collagen protein fibers arranged around inorganic components in regularly. Hydroxyapatite is about 65% mass fraction in human bone, and more than 95% mass fraction in human enamel, hydroxyapatite without toxicity and possess good biocompatibility, can be formed a strong chemical combination [...]
In this paper, silk fibroin/calcium phosphate composite was prepared and its structure and properties were studied, based on the preparation of calcium phosphate cement (CPC).As one of the main components of CPC, tetracalcium phosphate (TTCP) was prepared by wet method from the presoma, which was calcined in furnace and cooled in different ways. The results [...]
Coronary stenting is largely used in percutaneous transluminal coronary interventions because of the minimal trauma and outpatient treatment. Bare metal stents present excellent mechanical performance, but may lead to restenosis due to the permanent existence of stents. Therefore, a new generation of stents prepared from biodegradable polymers has received growing attention due to their outstanding [...]
The composite material based on hydroxyapatite is a common material for bone repair. In this paper we prepared composites of nano-hydroxyapatite with siloxane modified (HA-g-Si) and siloxane. It is an Organic-inorganic hybrid nanocomposites which can be prepared by photopolymerization. The preparation and characterization were described in detail. Include the following parts:1. The hydroxyapatite with nano-crystalline [...]
Background Since 1899 liquid paraffin wax was used as skin and soft tissure filling agent for the first time , clinical scholars research a lot of filling materials on injection and its clinical application and Achieved many progress. More and more injection filler is used in cosmetic and plastic surgery to correct deformity of human [...]
Hydroxyapatite is the main inorganic component of natural bone, and has goodbiocompatibility, bioactivity and osteoconduction. Hydroxyapatite has the calcium andthe phosphonium, the essential elements of the human body. When the hydroxyapatiteis implanted in the body, the calcium and the phosphonium could be educed in thehumoral and absorpted by the organism, forming chemical bond with the [...]
Background At present, a more satisfactory treatment of bone defects is autogenous bone graft, but there are many faults , such as limited sources, the impact of reactive functional , pain and infection, so clinical application is limited . Find a substitute of autogenous bone material has become the Orthopedic Research hotly. Bone cement has [...]
