1,6,7,8) Mechanical roughening of the metal or ceramic with aluminium oxide air abrasion has been described as the most effective surface treatment for fractured metal ceramic restoration
A glass ceramic based on lithium disilicate (LD) (SiO2- Li2O) crystals has been developed to extend the use of resin-bonded ceramic restorations
for bridge construction.
The system allows Concerned Dental Care's dentists to repair a damaged tooth in about one hour using tooth-colored ceramic restorations
Form grinding of dental ceramics (milling units) changed from a less precise diamond grinding wheel, which required more clinical adjustment, to a more precise 2-bur system in 2006 with a reduced diameter at the tips allowing for a more optimal internal and external detail of the ceramic restoration
The treatment planning was defined, therefore, in two phases: an initial stage to ensure the eruption of second molars, a second stage to establish aesthetic appearance by metal ceramic restorations
without orthodontic therapy.
Heavy occlusal forces: Ceramic restorations
may fracture when they lack bulk or are subjected to excessive occlusal stress, as in patients who have bruxing or clenching habits.
Marginal and internal fit plays an essential role in clinically evaluating the long term success of a ceramic restoration
in the oral cavity.
The physical and mechanical properties of resin cements may be affected by the thickness and microstructure of ceramic restorations
Sometimes, single crowns cannot simply be tapped off the abutments, and the retrieval may result in total destruction of the restoration, especially if it is a metal free ceramic restoration
The shade of the ceramic restoration
with a resin cement layer was evaluated by cementation after the resin disc surface was etched with 37% phosphoric acid (Etch, Schaan Liechtenstein, Ivoclar Vivadent) for 10 seconds, washed with an air/water jet for 15 seconds, coated with an adhesive system (Excite) for 10 seconds, and light activated for 10 seconds.
The company produces treatment centers, imaging systems, handpieces and hygiene systems as well as systems for computer-aided ceramic restoration
(dental CAD/CAM systems).
Ratings could be raised should Sirona's record improve EBITDA levels through a combination of the new cost program, or with greater-than-expected revenues growth, perhaps via the performance of its ceramic restoration
Composite resin materials contain organic matrix which is the main cause of chemical alteration as compared to inert metal or ceramic restorations
Achieving natural esthetics during full mouth rehabilitation is possible with modern all ceramic restorations
Jain AR, Nallaswamy D, Ariga P, Philip JM (2013) Full mouth rehabilitation of a patient with reduced vertical dimension using multiple metal ceramic restorations
