Onley – Inley

Onley-Inley is a large filling character approach that is prepared in the laboratory to compensate for the loss of substance in cases where tooth material loss is excessive.

If the material loss is less than 3/4 of the tooth and the chewing sharpness (cusp) is not lost, inlay is done, if the loss of substance is more than 3/4 and this loss includes cusps, onlay is done.
