Advancements in Bone Cements: A Review of Ceramic, Glass and Glass-Ceramic Materials and Their Reinforcements for Orthopedic Applications | Chapter 5 | Chemical and Materials Sciences: Developments and Innovations Vol. 6

Ceramics, glasses and glass-ceramics have now been accepted as viable biomaterials. Injectable bioactive, biodegradable, mechanically strong and fracture-resistant bone cements are of considerable interest. Therefore, various types of bone cement have been developing having high strength, fracture resistance properties and bioactivity for biomedical applications. Recently, research has been envisaged to improve the performance of existing bone cements. Different bioactive composite bone cements have been prepared by reinforcing certain reinforcing materials such as alumina, toughened zirconia and hydroxyapatite ceramics into ceramic, glass and glass-ceramic matrix. Recently, improved biodegradable and engineered bone cement materials have been prepared by using various novel methods. The current paper is focused on ceramic, glass and glass-ceramic-based bone cements and their probable orthopaedic applications.

Study about Fabrication and Evaluation of Different Thermal Barrier Coating Systems | Chapter 06 | Research Developments in Science and Technology Vol. 1

 Using vitreous enamelling and atmospheric plasma spraying (APS) processes, a new thermal barrier coating (TBC) system with an 8-YSZ top coat, glass-ceramic bond coat, and nimonic supper alloy substrate was created. The APS process was used to create a conventional TBC system consisting of an 8-YSZ top coat, a NiCoCrAlY bond coat, and a nimonic supper alloy substrate. The purpose of this research was to evaluate the thermal cycle performance of glass-ceramic bonded TBC systems to traditional TBC systems. X-ray diffraction analysis for phase identification, scanning electron microscopy for microstructural inspection, energy dispersive X-ray analysis for elemental composition determination, and a Vickers hardness tester for hardness evaluation were used to evaluate both TBC systems. Both TBC systems were also subjected to heat cycling testing at 1000oC for 250 hours using both air and water quenching methods. When comparing the glass-ceramic bond coated TBC system to the standard TBC system, a more gradual transition in microhardness values was discovered, indicating that the new TBC system will provide more reliable performance. Thermal cycling at 1000oC revealed that both TBC systems were stable under air quenching testing for 250 cycles, however coating spallation was seen in water quenching tests for 150 cycles for both TBC systems. Furthermore, the old TBC system showed considerable oxidative weight gain, whereas the new TBC system did not.

Thickness and Fracture Toughness Relationship in Ceramic Partial Restorations | Chapter 15 | Issues and Developments in Medicine and Medical Research Vol. 8

 Concerns about the aesthetics and biocompatibility of dental restorations are growing. Ceramic materials were created in response to the growing need for tissue preservation, aesthetics, and fracture resistance. However, their high clinical failure rate in posterior sites is a significant disadvantage. The effect of thickness and material type on the resistant fracture of ultra-thin ceramic restorations is described in this work. The restorative portion of the procedure should not damage the remaining tooth structure any further. Traditional onlays and full crowns are being replaced with ultrathin restorations (veneers, onlays, and inlays). the technical requirements for the success and favourable prognosis of those novel restorative designs based on tooth preparation control with diagnostic wax-up, provisionalization, and the utilisation of CAD-CAM technology .

A Detailed and Comparative Study on Conventional Sintering with Microwave Sintering and Vacuum Sintering of Y2O3-Al2O3-ZrO2 Ceramics | Chapter 12 | Current Perspectives on Chemical Sciences Vol. 6

 This chapter focused on comparative studies on conventional, microwave and vacuum sintering of alumina-added stabilised zirconia yttria (YSZ). When energy and time savings are involved, microwave sintering has been found to be the most effective sintering technique. In contrast to the conventionally sintered ones, microwave and vacuum sintered specimens display improved densification at lower temperatures. In contrast to the traditional and vacuum sintered specimens, the microwave sintered specimen displayed the highest hardness. In addition, it was found that the size of the particle had a prominent role in regulating densification enhancement.
