background: bone tissue engineering requires materials that are biocompatible, mechanically suited for bone function, integrated with the host skeleton, and support osteoinduction of the implanted cells for new bone formation. the aim of this study was to compare the osteogenic potential of xenograft with hydroxyapatite/β- tricalcium phosphate (ha/β-tcp) scaffold. methods: new zealand rabbits (...

Starting powders of silicon-substituted beta-tricalcium phosphate (β-TCP/Si) were prepared by the polymerized complex method. Silicon ions blended up to 3.0 mol% total P content. The raw product powder was calcined at 1000 °C, formed into pellets, and sintered 1120 °C for 24 h. resultant bodies showed that a single phase β-type tricalcium (β-TCP) can be obtained with silicon addition 0-2.0 subs...

This paper describes a method for preparing chitosan fibers modified with hydroxyapatite (HAp), tricalcium phosphate (β-TCP), and HAp/β-TCP nanoparticles. Fiber-grade chitosan derived from the northern shrimp (Pandalus borealis) and nanoparticles of tricalcium phosphate (β-TCP) and hydroxyapatite (HAp) suspended in a diluted chitosan solution were used in the investigation. Diluted chitosan sol...

63 Introduction Bone defects attributed to serious periodontitis, trauma, and injury are commonly encountered in the fields of dentistry, craniofacial surgery, and orthopedics. Although autogenous bone grafting is still considered the gold standard for treatment, this process has several drawbacks, such as the requirement of a second surgery and the limited availability of collectable bone [1]....

PURPOSE To investigate the effect of platelet rich fibrin (PRF) and beta tricalcium phosphate (β-TCP), alone or in combination, on bone regeneration in pig tibial defects. METHODS Four standardized defects were prepared in both tibias of three adult male pigs. The first defect was left unfilled as a control; the others were grafted with either PRF, β-TCP or PRF mixed with β-TCP. All animals w...

Foraminifera carbonate exoskeleton was hydrothermally converted to biocompatible and biodegradable zinc-tricalcium phosphate (Zn-TCP) as an alternative biomimetic material for bone fracture repair. Zn-TCP samples implanted in a rat tibial defect model for eight weeks were compared with unfilled defect and beta-tricalcium phosphate showing accelerated bone regeneration compared with the control ...
