The results obtained following one of the two methods indicate the dimensions which the pre-sintered prosthesis must have before being fired in the oven. These values are based on the experience of CO.N.CE.P.T. following various tests conducted considering machinability, density of the "green" (unsintered) product and final density.
20181218Presintered Zirconia Sintered Zirconia Most zirconia frameworks are fabricated by machining a porous or partially fired block Used as cores for crowns and FPDs Softer and easier to mill Milled to larger size(20%) Shaped by carbide burs Post sintering Sintering time-6-7.5 hours Sintering temperature-1350- 15300 C No need of post sintering No
Few studies have investigated the marginal accuracy of 3-unit zirconia fixed partial dentures (FPDs) fabricated by computer-aided design/computer-aided manufacturing (CAD/CAM) system. The purpose of this study was to compare the marginal fit of zirconia FPDs made using two CAD/CAM systems with that of metal-ceramic FPDs.
Zirconia is a pre-shaded, pre-colored layered disc from Noritake that can provide highly aesthetic results while minimizing the production process in the laboratory. Because of these multilayers, technicians are able to achieve natural tooth colors by only polishing or glazing the final restoration; no dipping or staining of the crowns are

The lower mid-range is one of the most overlooked, yet perhaps one of the potentially most exciting, of the temperature ranges. Within this range, most earthenware and other low-fire clay bodies actually mature to their strongest and most durable state.
Cercon® brain expert milling system from DENTSPLY capitalizes on the exceptional strength, reliability, and biocompatibility of translucent zirconia. The Cercon® zirconia restorations are produced with CAD/CAM technology for precise marginal fit and can be prescribed for a wide range of indications with performance results comparable to the
Objectives: This study determined the flexural strength of one hipped and eight presintered zirconia and evaluated the results using different estimation methods of Weibull statistics. Materials and methods: Presintered zirconia specimens were prepared in white state and sintered according to each manufacturer's instructions.
For the cercon system the pre-sintered zirconium oxide blocks were sandblasted with 120µm aluminium oxide particles at 0.2HPa pressure, IPS empress disc were sandblasted with 50µm glass particles at 0.15HPa pressure, Vitablocs mark 2 were cut from CAD-CAM and roughened with 80µm fine grain diamond stone.
eco sintering oven still has suﬃ cient capacity for a sintering bowl Ø 100 mm for approx. 25 units. The door stop can be mounted right and left. The CORiDRY pre-drying device ensures rapid and uniform drying of the colored zirconium dioxide frameworks through air circulation. The device is CE-certiﬁ ed and easy to use.

Combined with state of the art CAD/CAM technology, fabrication of zirconia frameworks requires nothing more than few keyboard clicks while the design, milling, and sintering became fully automated procedures . On the other hand, zirconia has a brittle nature and is sensitive to handling procedures . In a recent study, the flexure strength of
