Nanoscale surface characterization of biphasic calcium phosphate, with comparisons to calcium hydroxyapatite and β-tricalcium phosphate bioceramics.
OBJECTIVES It is our aim to understand the mechanisms that make calcium phosphates, such as bioactive calcium hydroxyapatite (HA), and biphasic calcium (BCP) and β-tricalcium (β-TCP) phosphates, desirable for a variety of biological applications, such as the filling of bone defects. METHODS Here, we have characterized these materials by X-ray photoelectron spectroscopy (XPS), X-ray diffractio...
متن کاملA New Mixture of Nano-structure of Potassium-incorporated Hydroxyapatite/β-tricalcium Phosphate/calcium Pyrophosphate
The new triphasic potassium−substituted hydroxyapatite (KHAP), β−tricalcium phosphate (β−TCP), and calcium pyrophosphate (CPP) proportions using easy sol−gel method were synthesized. The prepared powders was characterized by X–ray diffraction (XRD), Fourier transform infrared (FTIR), Differential thermal behavior (DTA) analysis, Energy Dispersive X–ray Analysis (EDXA), and Brunauer–Emmett–Telle...
متن کاملthe effect of calcitonin on increasing the effectiveness of hydroxyapatite and β-tricalcium phosphate in bone regeneration
introduction : osteon® is an alloplastic material containing 70% hydroxyapatite and 30% β-tcp. calcitonin, a hormone produced by the thyroid gland, not only prevents bone resorption by reducing both the number and the activity of osteoclasts, but also stimulates bone formation. considering the favorable effects of calcitonin on bone formation, we hypothesized that the addition of calcitonin to ...
متن کاملBone preservation in dehiscence-type defects using composite biphasic calcium sulfate plus biphasic hydroxyapatite/β-tricalcium phosphate graft: a histomorphometric case series in canine mandible.
OBJECTIVES To examine bone formation in dehiscence defects using biphasic hydroxyapatite/β-tricalcium phosphate plus biphasic calcium sulfate (BCP/BCS). MATERIAL After extractions, 24 mandibular buccal dehiscence defects (3 × 3 mm) were treated with BCP/BCS (E), membrane (MC), or control (NC). Histology and histomorphometric analysis were performed. RESULTS After 6 weeks, bone formation was...
متن کاملComparative Study of Bone Repair Using Porous Hydroxyapatite/ β-Tricalcium Phosphate and Xenograft Scaffold in Rabbits with Tibia Defect
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 (...
