Mineralized polymer composites (MPC) are recognized as potential fillers of bone defects. Though bioceramics exhibits quite a good bone-bonding and vascularization, it is considered to be too stiff and brittle for using alone. Thus, the use of polymer scaffold instead of bioceramics has several advantages including combining the osteoconductivity and bonebonding potential of the inorganic phase...
Biomaterials include bioceramics, biometals, biopolymers and biocomposites and they play important roles in the replacement and regeneration of human tissues. However, dense bioceramics and dense biometals pose the problem of stress shielding due to their high Young’s moduli compared to those of bones. On the other hand, porous biomaterials exhibit the potential of bone ingrowth, which will dep...
We have investigated the effects of different growth factors on the proliferation and osteogenic potential of primary cultures of human bone marrow stromal cells (BMSC). Fibroblast growth factor (FGF)-2 was the most effective in promoting growth of these cells in vitro. The size of colonies formed in clonal conditions was approximately 2.5 times larger in presence of FGF-2. Also the morphology ...
A review of classes of biomaterials and their applications is presented. Particular interest is paid to bioceramics, calcium phosphates and hydroxyapatite which are the leading biomaterials employed today. Several methods for producing hydroxyapatite are presented, including the characteristics and disadvantages of each methodology reported in specialized literature. The main trends of the mode...
Understanding of interactions between cells and biomaterials is a huge parameter for improving tissue engineering and regenerative medical fields. Many different materials have already been tested (including calcium phosphate ceramics) and it has been established that surface characteristic is a parameter that influences cell responses. The aim of this work was to characterize calcium phosphate...
The physical properties of bioceramics have made them ideal for a variety of prosthetic devices. Their porous structure allows fibrovascular tissue to invade the implant and secure it and provides a surface for muscular attachment. This process has been well-documented in animal studies; however, this case report describes the periodic imaging changes seen in a 67-year-old man following placeme...
Abstract Snail ( Achatina fulica ) is one of the sources duck fodder commonly used by local breeders to meet protein needs poultry farms. However, its shells as a by-product are rarely and just become waste. To overcome this problem, we try utilize waste be source bioceramic. contain lot calcium which can precursor make bioceramics. One bioceramics that has potential tricalcium phosphate (TCP) ...
While the reciprocity between bioceramics and living cells is complex, it is principally governed by the implant's surface chemistry. Consequently, a deeper understanding of the chemical interactions of bioceramics with living tissue could ultimately lead to new therapeutic strategies. However, the physical and chemical principles that govern these interactions remain unclear. The intricacies o...
