Porcelain inlay-onlay are superior aesthetic fillings that have maximum durability. They are prepared in a laboratuary. We can apply inlay-onlay fillings to the teeth which need large fillings. These fillings are preferred because under construction they require more less material loss according to porcelain crowns. Just decay is cleaned and measurement is taken. Porcelain inlay fillings are pasted to teeth with a special glue(adhesive system).
