Microstructural, mechanical, and thermal-shock behavior of hot-gas candle fiters obtained from different manufacturers have been evaluated. These filters include both monolithic ceramic and composite materials. Based on the results obtained so far, composite filters perform better than monolithic ceramic filters in a thermal-shock environment. During thermal-shock testing, the monolithic cerami...

A single implant-supported restoration is one treatment alternative to consider for the replacement of a missing tooth. Technological advances in materials and machining have led to the development of a densely sintered aluminum oxide ceramic abutment, designed and machined using CAD/CAM technology. This manufacturing method improves management of the subgingival depth of the crown/abutment int...

Proper, intelligent use of materials and technology should be utilized for the benefit of the patient. This case report presents a patient with a badly broken premolar tooth demanding high esthetic all-ceramic restoration. Following multiple procedure tooth was restored with zirconia all ceramic restoration. Multiple procedures to save a tooth are a really worthy, in the interest of patients. U...

Based on the optical characteristics of PLZT (Lead Lanthanum Zirconate Titanate) electro-optic ceramic, two kinds of electro-optical deflectors, triangular electrode structure and optical phased array technology, are studied in detail by using transverse electro-optic effect. Theoretically, the electro-optic deflection characteristics and mechanisms of the deflectors are analyzed; experimentall...

Issues concerning powder consolidation methods compatible with the colloidal approach and issues associated with other powder processing steps, viz., den-sification and microstructural control, are presented with regard to research directions leading to more reliable ceramics. 1. Introduction With their multiplicity of elemental combinations and crystal structures, ceramics exhibit unique prope...

The development of dental materials during the last few years is related to many factors, such as patient aesthetics requirements and also the increase in usage of CAD/CAM technology. The literature review shows the most used classes of indirect restorative materials and it demonstrates how the evolution of metal-free materials has reached a new level. Research combined with manufacturing techn...

Osteogenesis imperfecta (OI) is a heterogeneous disorder of connective tissue that manifests mainly as skeletal deformity and bone fragility. Dentinogenesis imperfecta (DI) is sometimes an accompanying symptom of OI. The treatment protocol of these patients varies according to the clinical appearance. The case report here describes complete mouth rehabilitation of an 18-year-old male patient wi...

A new integration concept for micro-nano-integration based on a new bonding technique between nano-scaled, modified Black Silicon (BSi) and an adapted, unfired LTCC substrate is presented. The novel technique enables to combine advantages of silicon and ceramic technology, especially electrical and fluidic interconnects from nmto mm-scale. Current bonding concepts of silicon on ceramics need jo...

The development of low-temperature co-fired ceramic (LTCC) technology is increasing the interest in ceramic pressure sensors (CPS). This technology and materials in combination with conventional thick-film technology offers a feasible solution to increase the sensitivity of pressure sensors and the flexibility in design, both with the aim to replace silicon-based pressure sensors in some applic...
