Conservative Crown or Porcelain Onlay

This patient had a failing silver-mercury filling. The size of the missing tooth was too large to just replace it with a composite filling so some sort of porcelain restoration was required. We choose a conservative porcelain onlay instead of a porcelain crown. Although the procedures are very similar the onlay allows us to keep all of the healthy part of the tooth that would have to be removed with a crown preparation. Then we bond in the onlay just like we bond porcelain veneers. It’s more difficult than crowning the tooth but the end result is a healthier more conservative and natural treatment.
