Inlays and onlays are restorations used to
repair back teeth which have mild to moderate decay or cracked and fractured
teeth that are not sufficiently damaged to need a crown. A dental inlay is similar to a filling and fits inside the
cusp tips of the tooth. A dental onlay is more extensive and extends over the
cusps of the treated tooth.
Ideal candidates for an inlay or an onlay
typically have too much damage or decay in the tooth structure to be successfully
treated using a filling but have sufficient healthy tooth remaining to avoid
the need for a crown. This allows the dentist to conserve more of the patient’s
original tooth structure.
Dental inlay/onlay are stronger than the traditional fillings. The tooth is first prepared then an impression is followed which is send to the laboratory for the inlay/onlay to be made and then fitted using a dental cement. Dental inlay/onlay can be made from composite, porcelain or gold.
