Therefore, zirconia all-ceramic crowns are superior to various metal alloys in terms of biocompatibility, including gold materials. Zirconia Crown. Safe non-metallic materials. At present, zirconia is the only mineral in the natural world, which does not contain any metal, and it is safer after the medical clean processing. No obstruction to
Teeth whitening is also known as teeth bleaching. In summary, the process involves a chemical that is applied to the teeth and a light-emitting diode (LED) that is shone on the chemical to activate it. Teeth whitening is a very effective treatment targeting stains that may have been caused by different factors associated with our lifestyle
It is of paramount importance that these implants be not only functional, but capable of enduring for their anticipated useful life. In the case of fixed dental prosthetics (FDPs), namely crowns (single prosthetic), bridges (several joined prosthetics) and dentures (full upper or lower jaw prosthetics), the aim is to maximise this lifespan.
2015623The majority of all-ceramic restorations have a two-layer structure that is comprised of a weak ceramic veneer laid over a strong supporting core.1 In restorative dentistry, zirconia is commonly used as the core material in the manufacture of crowns, fixed dental prostheses (FDPs), and full-contour crowns because of its excellent esthetics

RESTORATIVE DENTAL GLASS-CERAMICS (RDGCS) Glass-ceramics A restorative material that mimics the tooth properties can The ﬁrst dental glass-ceramic was a mica-based material R be used as inlays, onlays, full crowns, partial crowns, known as DicorV that was introduced by Malament and bridges, and veneers.
201647After burn out, the articles, so-called "brown" bodies, were then sintered at temperatures lower than 1200° C. to reach full density. Sintering can be carried out in dental furnaces, traditional high temperature furnaces, or hybrid microwave furnaces.
Metallurgical furnaces are mostly used for (i) extraction of metals from ores, (ii) calcining and sintering of ores, (iii) melting, refining and alloying of metals, (iv) heating of metals, (v) carbonizing of coals, and (vi) heat treatment of metals etc. Energy sources for metallurgical furnaces are (i) combustion of fossil fuels, such as solid
201282Conventional sintering was carried out in a Deltech furnace at 1450° C. for 2 hours. Microwave sintering was carried out in a Thermwave 1.3 furnace from Ceralink Inc. (Troy, N.Y.), a 1.3 watt single mode microwave with SIC susceptors at 1450° C. 10 to 20 minutes. The best results were obtained using the 10 minute hold.
2019114It was concluded that the monolithic zirconia crowns produced by high-speed sintering showed no significant difference in the marginal gap and the fracture load after aging compared to conventional sintering. Therefore, the high-speed sintering seems a valid method of producing tooth-borne monolithic zirconia crowns.

Single crowns made from CZR with zirconia can be used in the posterior as well as anterior due to its extremely high flexural strength. The combination of CZR and zirconia will give you enhanced esthetics and fit with maximum strength for an overall superior restoration.
The discs were then randomly divided into two groups according to sintering methods applied (n=48). The first group was sintered in a microwave furnace (Microsinterwave, A1614, AZ) with a power output of 1.4 kW; in a total of 90 minutes, with 30 /min temperature rise to a maximum of 1600.
