Ceramics are widely used biomaterials in prosthetic dentistry due to their attractive clinical properties. They are aesthetically pleasing with their color, shade and luster, and they are chemically stable. The main constituents of dental ceramic are Si-based inorganic materials, such as feldspar, quartz, and silica. Traditional feldspar-based ceramics are also referred to as "Porcelain".

The earliest successful porcelain systems used conventional feldspathic porcelain, derived from the natural mineral feldspar. This material was used for producing all-ceramic jacket crowns, which were very esthetic. Dental feldspathic porcelain is predominantly a glass material with an amorphous (non-crystalline) structure.
For dental porcelains, the kaolin was omitted and could be considered to be a feldspathic glass with crystalline inclusions of silica. Kaolin is a hydrated aluminum silicate (Al2 O 2SiO 2 2H 2 O) and acts as a binder in domestic porcelains. Quartz remains unchanged during the firing process and acts as a strengthening agent.

Dental porcelain has been used as artificial porcelain teeth in complete or partial denture, porcelain crown or inlay, and dental cement. Ceramics have also been used to restore carious enamel and dentin or missing teeth. For classical dental porcelain, quartz, kaolin, and feldspar were the raw materials used for preparing the porcelain.
Porcelain (/ ˈ p ɔːr s əl ɪ n /) is a ceramic material made by heating materials, generally including a material like kaolin, in a kiln to temperatures between 1,200 and 1,400 °C (2,200 and 2,600 °F). The toughness, strength, and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and the formation of the mineral mullite within the body at ...

Dental cements are basically glasses. Initially, silicate cements were introduced. They constitute the first dental cement to use glass as its component. The cement powder contains a glass of silica, alumina and fluorides. The liquid, is an aqueous soluti on of phosphoric acid with buffer salts.
A typical dental porcelain will mainly consist of a mixture of feldspar with, say, about 15 ~ 20% powdered quartz and a few percent of kaolin as a binder. Kaolin is an hydrated clay mineral, Al 2 O 3 ·2SiO 2 ·2H 2 O, and is in the form of very fine hexagonal plates in the range 1 ~ 5 μm diameter and about 1 μm thick.
The most common ceramics used in dentistry are alloys of 3 main metallic oxides (SiO2, Al2O3, K2O). Composition of Dental Ceramics and Dental Porcelain: 1) Feldspar: 60 to 80%. this is a mixture of Sodium Aluminium Silicate. Na2O.Al2O3.6SiO2 (Albite) and potassium aluminum Silicate K2O.Al2O3.6SiO2.

Portable (table-top) steam sterilizers are used in outpatient, dental, and rural clinics. 840 These sterilizers are designed for small instruments, such as hypodermic syringes and needles and dental instruments. The ability of the sterilizer to reach physical parameters necessary to achieve sterilization should be monitored by mechanical ...
These are composed of three basic elements: feldspar (the main component); quartz, and kaolin in various percentages. Dental porcelain is different from ceramics in general use, and although initially it used to contain a small percentage of kaolin (4% to 5%), this .
Dental ceramics are usually composed of nonmetallic, inorganic structures primarily containing compounds of oxygen with one or more metallic or semi-metallic elements. Ceramics are used for making crowns, bridges, artificial denture teeth, and implants. ... Feldspar is responsible for forming the glass matrix . Feldspar is the lowest melting ...
Dental ceramics can be classified in a number of different ways, including by their composition, processing method, fusing temperature, microstructure, translucency, fracture resistance, and abrasiveness. 1 (For the purposes of this article, the term ceramic is used to include all metal-free restorations.) Generally, all-ceramic restorations have been confined to the anterior region until ...
feld·spar (fĕld′spär′, fĕl′-) also fel·spar (fĕl′-) n. Any of a group of abundant rock-forming minerals occurring in igneous, metamorphic, and sedimentary rocks, and consisting of silicates of aluminum with potassium, sodium, calcium, and, rarely barium. About 60 percent of the earth's outer crust is composed of feldspar. [Partial ...
The real force behind the advancement of digital dentistry is the revolution in material choices for both chairside and lab-produced restorations. CAD/CAM blocks or discs are used in conjunction with a dental mill to produce final or temporary restorations or a range of parts used in these restorations.
dental ceramics is usually in the form of quartz [1]. Because of the black appearance of nitrides and carbides, they are not used as biomaterials in dentistry [2]. The traditional type of dental ceramics are feldspar-based materials containing silica fired at temperatures above 870°C and composed of a tectosilicate mineral feldspar (KAlSi 3O
