    However, this might be only the case for gold. While short-term studies come to inconsistent conclusions, a respectable number of long-term studies detect no significantly lower failure rates of ceramic [4] or composite [5] inlays compared to composite direct fillings. Another study detected an increased survival time of composite resin inlays ...

    Nano-ceramic particles embedded in a resin matrix are less brittle and therefore less likely to crack, or chip, than all-ceramic indirect fillings. They absorb the shock of chewing more like natural teeth, and more like resin or gold fillings, than do ceramic fillings; at the same time they are more resistant to wear than all-resin indirect ...

    en.wikipedia.org/wiki/Conservation_and...

    Conservation and restoration of ceramic objects is a process dedicated to the preservation and protection of objects of historical and personal value made from ceramic. Typically, this activity of conservation-restoration is undertaken by a conservator-restorer , especially when dealing with an object of cultural heritage .

  5. Ceramic matrix composite - Wikipedia

    Fracture surface of a fiber-reinforced ceramic composed of SiC fibers and SiC matrix. The fiber pull-out mechanism shown is the key to CMC properties. CMC shaft sleeves. In materials science ceramic matrix composites (CMCs) are a subgroup of composite materials and a subgroup of ceramics. They consist of ceramic fibers embedded in a ceramic matrix.

    For example, the size, composition, crystallinity, or alignment of the fibers will dictate the properties of the composite. The interplay between matrix microcracking and fiber-matrix debonding often dominates the failure mechanism of SiC/SiC composites. This results in SiC/SiC composites having non-brittle behavior despite being fully ceramic.

  7. Dental restoration - Wikipedia

    en.wikipedia.org/wiki/Dental_restoration

    Fillings are recommended for small to medium-sized restorations. Inlays and onlays are more expensive indirect restoration alternative to direct fillings. They are supposed to be more durable, but long-term studies did not always detect a significantly lower failure rate of ceramic [21] or composite [22] inlays compared to composite direct ...

    Ceramic tiles have a multiple hit capability problem in that they cannot sustain successive impacts without quickly losing much of their protective value. [6] To minimise the effects of this the tiles are made as small as possible, but the matrix elements have a minimal practical thickness of about 25 mm (approximately one inch), and the ratio of coverage provided by tiles would become ...

  9. Dental amalgam controversy - Wikipedia

    en.wikipedia.org/wiki/Dental_amalgam_controversy

    Better dental health overall coupled with increased demand for more modern alternatives such as resin composite fillings (which match the tooth color), as well as public concern about the mercury content of dental amalgam, have resulted in a steady decline in dental amalgam use [82] in developed countries, though overall amalgam use continues ...
