Inlay Onlay
The inlay or onlay is a partial prosthetic piece recommended following a decay, a fracture of a part of the tooth or a replacement of an old filling that is no longer adapted.
It represents a very contemporary solution for restoration, from the mechanical, durability and aesthetic point of view:
Solid: by their ceramic constitution.
The ceramics used today for inlays/onlays have mechanical properties very similar to dental enamel.
In this way, the missing tooth part is replaced by a ceramic part with exactly the same shape and properties. This is called dental bio-mimicry.
Durability: made to measure by a prosthetist on the basis of an impression of the tooth made by the dentist, the quality of the joint between the tooth and the extremely fine inlay and the solidity of the ceramic make this type of restoration very durable.
The average life span of an inlay/onlay is 10 to 15 years.
Aesthetics: made in the laboratory by the dental technician, the inlay or onlay has a much more precise morphology and will merge with the natural tooth.
How does an inlay/onlay procedure work?
Two sessions are required:
1/ Preparation of the tooth (or teeth) that will receive the inlay or onlay: under local anesthesia, the tooth is prepared with a burr to remove decay or old defective fillings.
Then, an impression of the tooth is taken, before closing the cavity with a temporary filling.
2/ Bonding of the inlay / onlay with a bonding resin. A surgical field, called a dental dam, is placed before the assembly of the inlay in order to isolate the tooth from the rest of the mouth and to be in the best conditions to obtain a perfect and tight bonding.
