Porcelain Inlays and Onlays
An inlay is a filling made in the dental laboratory. The dentist prepares your tooth and takes an impression; following this a temporary filling is put into the tooth for a week or so. The inlay is constructed from porcelain, this makes it strong and very natural looking. Inlays last longer than white fillings and are recommended for larger cavities where white fillings would not be strong enough.
Uses of Dental Inlays and Onlays
The main use of inlays and onlays in modern dentistry is for cosmetic purposes. The cosmetic demands of modern society have seen an increase in the use of tooth-coloured restorations by dentists. Composite-resin or tooth-coloured filling material is not as strong and durable on the posterior teeth as newer ceramic (porcelain) materials so these are increasing being used as an alternative to placing traditional composite-resin or amalgam fillings. Porcelain is stronger and can be used in situations where traditional fillings may fail and it will not stain or discolour over time like composite-resin fillings. Gold is the traditional material of choice for inlays and onlays and it is an excellent material. However, due to aesthetic concerns there is less demand for its use in modern cosmetic dentistry.
