Your Go-To Guide For Cementation Of All Types Of Prosthesis (Part 1)

Main Content

Cementation is the final step of indirect restorations which, usually, we do not take very seriously – until the patient comes back with a dislodged crown repeatedly and we don’t understand where we went wrong! There are two objectives for cementation or luting 1 –

  • to help retain the restoration in place and
  • for a good marginal adaptation and seal.

If you are one of the many who only use GIC in their clinic, then take a look at various cements available along with their leading brand names, primary advantages & disadvantages, indications with literature supported recommendations and you will be in for a pleasant surprise!
