Inlay-Onlay - Maria Lalousi

27 Oct


When a tooth has decayed or fractured to such an extent that a filling is insufficient to repair the tooth but the structure of the tooth is still sound, an inlay or onlay can be used to restore the tooth and salvage the remaining healthy parts of the tooth rather than re-shaping the sound portion of the tooth to fit under a crown. Inlays and onlays are less invasive treatment option used to restore the back teeth which otherwise had to be restored with full crown. Inlays and onlays are a form of indirect restoration. This means they are made outside of the mouth as a single, solid piece that fits the specific size and shape of the cavity. The restoration is then cemented in place in the mouth.

Inlays and onlays are made from composite, porcelain or gold. However, porcelain and composite inlays and onlays are aesthetically more appealing as they can be coloured to look natural. This often makes dental inlays and onlays a popular choice for those wishing to replace unattractive fillings that are made from metal.

This type of dental product is bonded into place around the cusps. Onlays are used to cover one cusp or more, whereas dental inlays tend to be used more as a filling between the cusps. This area is vulnerable to damage due to chewing and so is often prone to fracturing. If all cusps and the entire surface of the tooth is covered this is then known as a crown.

How long a dental inlay and/or onlay will last depends on a number of factors: A key influence on how long they exist is the material that the inlay or onlay is composed of. Also, the actual teeth that the product is applied to can be a big determining factor in how long they last for.

How forceful chewing is as well as choice of food, the level of care that is taken by the patient for the inlays or onlays as well as the oral hygiene routine of the patient. It is also important that the dentist is visited regularly to make sure that the inlays and onlays are intact.
