A crownlay is a type of dental restoration. == Description == A crownlay is a hybrid dental restoration typically placed over an endodontically treated tooth that is more conservative than a normal full coverage crown, but less conservative than a normal onlay. Crownlays incorporate an extension of extra restorative material on the underside of the restoration into the excavated pulp chamber following root canal therapy, taking advantage of the extra surface area afforded in this space on the interior aspect of the preparation, thereby sparing the external walls from needing as much tooth reduction. The use of a crownlay results in the conservation of more healthy, natural tooth structure than is otherwise possible.
