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]....
Herein, we show that the enhanced osteogenecity of octacalcium phosphate (OCP) biomaterial, recently identified as an important element in hybrid organic–inorganic nanocomposites involved initial hydroxyapatite crystal expansion mammal bones, results from chemical property, stemming presence lattice strain and dislocations. Two types OCPs were synthesized by wet-chemical processing (c-OCP) abse...
This study aimed at preparing and studying the properties of nanoparticles of calcium phosphate (nCaP) with Ca/P ratios ranging from 1.0 to 1.67 using a spray-drying technique. Micro-structural analyses suggested that the nCaPs with Ca/P ratios of 1.67 to 1.33 were nano-sized amorphous calcium phosphate (ACP) containing varying amounts of acid phosphate and carbonate. The nCaP with Ca/P ratio o...
Biomaterials are increasingly used for bone tissue regeneration because of their potential to overcome the morbidity caused by autologous grafts and allografts. A combination properties is required, as biocompatibility, osteoconductivity, good mechanical strength fracture toughness. In this research, a compound alumina matrix with calcium titanate phosphate proposed. Magnesium stearate was poro...
