Onlays are an advanced solution in the cases where remains little tooth structure as a
result of extensive coronal tooth destruction. In these situations, they are often
a better alternative than composite fillings. From records the dentist has provided,
onlays are created by a dental technician in a laboratory before being fitted and
bonded to your teeth in the office. Since healthy areas of your teeth remain untouched,
onlays allow us to leave more of your natural tooth structure intact than we would be
able to do using traditional dental crowns.
Another advantage to using onlays is that they are made of porcelain or composite
resin, not metal, to match the natural color of your tooth.
Unlike conventional composite resin fillings, onlays composites do not
shrink when bonded to the tooth, with a better control of the polymerization
and thus a greater adaptation at the edges and better control of occlusal and
proximal tooth morphologie.
