Synergistic Properties-Driven Synthesis of Aluminides, Antiomonides, and Bioceramics
The synthesis, characterization, and properties of selected intermetallics and ceramic materials are presented in this dissertation. In our quest to grow single crystal intermetallics from the metal flux technique, new strategies were employed to avoid thermodynamically stable phases and to ensure …

Biocompatibility and Bioactivity of Calcium Silicate-based Dental Bioceramics
Tricalcium silicate dental bioceramics are bioactive ceramics. They are used to repair and treat iatrogenic, and pathological communications between the oral environment and mesenchymal tissue through tooth structure, or as a retrograde root filling after root resection. They are placed in direct …

An investigation into the effects of two bioceramics on rat mandibular bone
… these guidelines is that although both of these bioceramics have been used in clinical studies there are no established guidelines to indicate which clinical situation is best served by either dense hydroxyapatite or ß tricalcium phosphate. This is evidenced by the fact that many materials have …

Hydrothermally extracted nanohydroxyapatite from bovine bone as bioceramic and biofiller in bionanocomposite
… used to fabricate two types of biomaterials (HAP bioceramics and PLA/n-HAP bionanocomposite). The raw-HAP and calcined n-HAP powder samples were compacted into green bodies and were sintered at various temperatures (1000-1400°C) to produce HAP bioceramics. The best calcined n-HAP was mixed with …

Histologic evaluation of calcium phosphate coated endosseous implants prepared by spark discharge oxidation : a long-term study in the sheep
… layers of two implant types were coated with bioceramics during the oxidation process (type 1 and type 2), whereas a third implant was successively coated by hydroxyapatite-(HA-)gel immersion successive to the oxidation process (type 3). Experimental bioceramic coatings consisted of pure …

Thermal spray of a drug delivery system onto femoral orthopaedic implant
Hydroxyapatite bioceramics are proven to be good materials for bone replacement and repair applications, due to their similarity in chemical composition to bone. Plasma spraying has been commonly used to apply hydroxyapatite coatings onto metallic implants for use in orthopaedic surgeries. The …

Novel processing of porous bioceramic structures
… 100 – 400 μm and porosity >90%, are preferred. Bioceramics have been used in numerous orthopaedic applications since the 1960s. While bioinert materials such as zirconia have been used in load bearing applications due to their impressive mechanical properties, bioactive materials such as …

Effects of Surface Characteristics of Hydroxyapatite and Substituted Hydroxyapatites on Protein Attachment and Angiogenesis
… (HA) is one of the most widely studied bioceramics for BTE, due to its close resemblance to the mineral component of bone. As bone mineral contains various ionic substitutions that play a crucial role in bone metabolism, attempts to improve the bioactivity of HA have focussed on adding …

pH Change Following Smear Layer Removal and Final Rinse with 95% Ethyl Alcohol Using Calcium Hydroxide Medicament or BC Sealer
Introduction: An in vitro investigation of pH change at the external root surface after final rinse of 95% ethyl alcohol using Ultracal XS, Calasept Plus, or obturation with BC sealer. Methods: 80 single rooted extracted human teeth were decoronated with a standardized root length of 15mm. All root …

Effect of Calcium Phosphate Ceramic Architectural Features on the Self-Assembly of Microvessels In Vitro
One of the greatest obstacles to clinical translation of bone tissue engineering is the inability to effectively and efficiently vascularise scaffolds. This limits the size of defects that can be repaired, as blood perfusion is necessary to provide nutrient and waste exchange to tissue at the core …
