PORCELAIN FILLING - INLAY / ONLAY
They are the kind of restorations prefered if more than the half of the chewing surface of the teeth lost due to the cause of fractures or caries. This is a treatment method between a filling and a crown application. Onlays are used in more material losses than inlays. They are prepared in laboratory with the use of special molding porcelains. These kind of porcelains are well adapted to the teeth esthetically and more resistant to the chewing forces.
How is the applications of porcelain filling?
Usually it takes about 2 seassions. First, the old filling or caries is removed from the teeth and the cavity is formed. A cast is taken from the newly prapered cavity and send to the laboratory. During this period of time, a temporary filling is placed on teeth. On the second session, onlay or inlay which came from the laboratory is checked due to its adaptation, color, height and adjustments are made if necessary. If there is no other problem, it is cemented to teeth with special bonding agents. When there is a problem in adjustment, an extra session may be needed.
What are the advantages of porcelain filling?
Extra material loss of the teeth is prevented due to the fact that unlike appliying a crown, there is only removing of the existing caries and no other extra preparation. As they are made of porcelain, there won’t be any discoloration in time. They are well resistant to the chewing forces. They are quite esthetic and it takes only 2 sessions to apply them. The porcelain surface is greatly polished so no food will stick to the surface of them; as a result, they are hygienic. Cold-hot sensitivitys occuring after the application of composite filling do not appear in porcelain fillings and no new formation of caries can be observed.
