Full-porcelain dental materials include dental porcelain (porcelain meaning a high-firing-temperature ceramic), other ceramics, sintered-glass materials, and glass-ceramics as indirect fillings and crowns or metal-free "jacket crowns". They are also used as inlays, onlays, and aesthetic veneers. A veneer is a very thin shell of porcelain that ...
If porcelain is to be applied to the gold crown, an additional minimum of 1 mm of tooth structure needs to be removed to allow for a sufficient thickness of the porcelain to be applied, thus bringing the total tooth reduction to minimally 1.5 mm. For porcelain or ceramic crowns the amount of tooth reduction is 2 mm. For metal, it is 1 mm.

This system can be used to remove both all metal crowns and metal-ceramic crowns, although with metal-ceramic crowns care should be taken to remove enough ceramic from the area where the hole created to reduce the chances of fracture. The minimum thickness of metal required for the lifting action is approximately 0.5mm.
Inlays are most commonly constructed in composite resin and ceramic materials. Both types have varying properties, however the general downsides to inlays include: Higher cost compared to a restoration, due to the need for a dental laboratory [11] Lengthier process as two appointment required i.e. increased chair time for patient [11]

Installation of a dental crown usually requires removal of significant healthy tooth material so the ...
