Modern day tissue engineering and cellular therapies have gravitated toward using stem cells with scaffolds as a dynamic modality to aid in differentiation and tissue regeneration. Mesenchymal stem cells (MSCs) are one of the most studied stem cells used in combination with scaffolds. These cells differentiate along the osteogenic lineage when seeded on hydroxyapatite containing scaffolds and c...

Hydroxyapatite/titania nanocomposites (TiHAp) were synthesized from a mixture of a titanium alkoxide solution and dissolution products of a Moroccan natural phosphate. The simultaneous gelation and precipitation processes occurring at room temperature led to the formation of TiHAp nanocomposites. X-ray diffraction results indicated that hydroxyapatite and anatase (TiO2) were the major crystalli...

In this study, the mechanical properties of bioactive coatings on Ti6Al4V substrates were investigated using instrumented nanoindentation. The aim was to observe the differences in the mechanical properties before and after immersion in collagen solution. The hydroxyapatite coatings were prepared through two processes: self-assembly in simulated body fluid and a hydrothermal method. Sintered hy...

objective(s):   the production of nano-hydroxyapatite by two encapsulated bacterial strains was the goal of current research.  materials and methods:   serratia marcscens atcc 14756 and pseudomonas aeruginosa ptcc 1570 were used by two methods including encapsulated form in 2% (w/v) alginate sodium powder and inoculated form (10%) in nutrient broth medium containing alginate sodium blank beads....

BACKGROUND Bone graft procedures have been used commonly in buco-maxillo-facial surgery. For this reason, many researchers have evaluated the bone substitutes. PURPOSE The present study evaluated soft and hard tissue reactions to two different hydroxyapatites HAs (synthetic HA and natural HA) and bioactive glass implanted into the sockets immediately after extraction. MATERIALS AND METHODS ...

Abstract The increasing of dental implants needs to be supported by local materials’ development as a form independence for nation. With its rich natural resources, Indonesia has the potential used implant material. Dental materials can in bioceramic consisting bioactive, bioresorbable, and bioinert. One bioactive concern today is glass-ceramics from basalt rock. Meanwhile, hydroxyapatite mater...
