A dental inlay is an indirect restoration or filling which is made with a solid ingredient like gold, porcelain or a cured composite resin. This is fitted into a tooth cavity and is cemented into its place. For this, a dentist uses fabrication technique. The dentist makes dental impressions a tooth and does not put a filling into the prepared tooth before it hardens.
An onlay is pretty much the same as an inlay. However, it is also inclusive of a replacement for a tooth cusp by covering the area where the cusp is.
What is the difference between inlays and fillings?
An inlay is used, the tooth-to-restoration margin is finished and polished up to a very fine line of contact to reduce tooth decay. Direct composite fillings, when pasted, shrink by a bit when they harden. This will lead to a bit of stress accumulating in the area. Sometimes, the whole procedure may fail due to this reason.
One more point in favor of inlays as compared with fillings is that one can use a wide variety of materials for this purpose. Even though inlays are priced pretty much higher than restorations, they are of a grade higher in quality. They can provide a decent resistant force to occlusal forces.
A detailed description of onlays
In the case of cuspal fracture, it is an onlay which will be needed as proper treatment. An onlay is an indirect restoration which is inclusive of a cusp or cusps. Onlays have benefits pretty much the same as inlays regarding the longevity and durability of the structure.
Care for inlays and outlays
Any dental restoration or treatment does stay good and healthy if one follows a strict oral hygiene program after that. In the case of inlays and outlays too, it is essential to maintain good care of teeth. Regular brushing twice a day is the norm in all cases. Also, one must aid and abet this with flossing activities as well.
One must also visit the dentist once every six months or so to check the inlays and onlays. They will recommend if any further procedure is to be done. Inlays and onlays, if properly cared for, can even last for up to 30 years. These, in fact, help to strengthen teeth up to 75 per cent. This is a positive technology when one considers since fillings can even cut short the inherent strength of the tooth or teeth by even up to 50 per cent.
Inlays and onlays, if done properly, will lengthen tooth life and reduce the requirement for more of dental visits in the coming times. This makes them the ideal form of procedure to be accepted by most people since it involves cutting short of future headaches as well.
