A dental restoration or dental filling is a dental restorative material used to restore the function, integrity and morphology of missing tooth structure. The structural loss typically results from caries or external trauma. It is also lost intentionally during tooth preparation to improve the aesthetics or the physical integrity of the intended restorative material. Dental restoration also refers to the replacement of missing tooth structure which is supported by dental implants.
In preparing a tooth for a restoration, a number of considerations will come into play to determine the type and extent of the preparation. The most important factor to consider is decay. For the most part, the extent of the decay will define the extent of the preparation, and in turn, the subsequent method and appropriate materials for restoration.
Root Canal Treatment Procedure::
1. Amalgam Fillings ( Silver Fillings ):
Amalgam fillings are also named as silver fillings. They are prepared by amalgamating the silver, tin and copper alloy with mercury. Mercury makes %45-50 of the compound and acts as a bond between the metals resulting in a highly strong filling. Amalgam which is improved through the almost 150 years that is on the market has widely served and is still serving to maintain teeth in mouth.
2. Glass Ionomer Cement:
As they bond chemically to dental hard tissues and release fluoride for a relatively long period modern day applications of GICs have expanded. The desirable properties of glass ionomer cements make them useful materials in the restoration of carious lesions in low-stress areas such as smooth-surface and small anterior proximal cavities in primary teeth. Results from clinical studies also support the use of conventional glass ionomer restorations in primary molars. They need not be put in layer by layer, like in composite fillings.
3. Composite Fillings( Tooth Coloured Fillings):
They are esthetic restorations that are generally used in the front teeth. But for the past two or three decades the has been tremendous improvements in the chemistry and bonding properties of those fillings so that nowadays even at the back molar teeth we confidentely are placing composite fillings because of their high strenght capacity against occlusal forces.
Inlays and onlays are fabricated, casted restorations thar are indicated for very large tooth losses which otherwise need to be crowned. After removing the decay and shaping the cavity impressions are taken and sent to the laboratory for either gold, composite or porcelain inlays and onlays. After they arrive from laboratory they are bonded in place with special cements and techniques. They require special and precise techniques.
