Dental Ceramic Layering Techniques

Today s ceramic restoration application despite its popularity gained through esthetical advantages and superior hygienically features has a fragile structure due to its low tensile strength quality.

Dental ceramic layering techniques.

Some of the techniques are rather complex using numerous shades and layers making them difficult to learn and use in daily practice. In the long run it can lose its endurance against shear and draw strengths that occur while chewing. Dental ceramics is applied in several layers normally 4 but it can be more. The background for basic techniques for building porcelain layers is explained with photographs in this chapter.

23 although these metal ceramic bilayers are still considered the gold standard for fpds. It is a thin layer positioned directly on the metal framework. This gives a natural vivid lustrous appearance to the veneers that create the most natural life like smile makeovers that can be achieved. Dental ceramics are sensitive to microcracks that show up on surfaces.

Traditionally fixed partial dentures fpds produced with a metallic infrastructure and a ceramic veneering layer have excellent clinical performance with studies showing an annual failure rate around 1 and a survival rate of 94 after 5 years of clinical follow ups. Esthetically these materials are preferred alternatives to the traditional materials in order to meet the patients demands for improved esthetics. Dental porcelain also known as dental ceramic is a dental material used by dental technicians to create biocompatible lifelike dental restorations such as crowns bridges and veneers evidence suggests they are an effective material as they are biocompatible aesthetic insoluble and have a hardness of 7 on the mohs scale. Normally the porcelain has the ability to glaze itself by forming a vitrified layer on the surface of dental porcelain ceramic containing a glass phase b.

Feldspathic veneers and crowns use a layering technique where layers of porcelain are laid down and the tooth is grown much like a pearl or natural tooth grows to create feldspathic veneers. Shade with depth in a metal ceramics system can be obtained only with a sufficient thickness of translucent porcelain. For certain dental prostheses such as three unit molars porcelain. The amount of abutment prepared should be greater than that in a full porcelain crown.

Over the last decade it has been observed that there is an increasing interest in the ceramic materials in dentistry. Applied or add on glaze. In this article a simple and predictable restorative technique will be described that concentrates on the recreation of dental tissues of natural thickness layer by layer. Dental ceramics are usually composed of nonmetallic inorganic structures primarily containing compounds of oxygen with one or.
