Treatments/ Porcelain onlays
I have great new teeth.
Sometimes a large part of a tooth is missing, for instance when there is a large cavity or an old filling in a tooth, or after a fracture. In these cases, there is not enough left of the original tooth to restore it in a durable way with composite (the white filling material).
Porcelain onlays are the preffered restorations in these cases. The old filling is removed or the cavity is cleaned, the tooth is prepared so that the onlay and the remainder of the tooth will form a strong unit. As much of the healthy enamel as possible is preserved.
Then, an impression is made and the dental technician produces the porcelain onlay. The onlay is made under high pressure and temperature to make it very strong so that it can withstand the daily effects of eating and drinking.
In the dental laboratory, the onlay can be finished precisely, so that colour, small details as white spots or discolourisations, and surface structure can be made to match the neigbouring teeth. After 8 working days the onlay will be placed in your tooth, and the treatment is completed.
This porcelain restoration is very strong, smooth and does not wear out or discolour. Often the restoration is hardly visible because of the resemblence with the original enamel of the tooth.
Generally it is desirable, when making onlays, to freshen up the original colour of the teeth with a Brite-Smile treatment, which enables us to choose a nice light porcelain colour. It is important to do this before making the onlays, as the colour of the porcelain cannot be changed after placement of the onlays.
A animation about porcelain onlays will illustrate the text in the future.
