What is Type three glass ionomer cement typically used for?

Type three glass ionomer cement is specifically formulated for use as bases and liners in dental procedures. This type of cement is known for its thermal insulating properties and its ability to release fluoride, which can help protect the tooth structure underneath. Its biocompatibility makes it a suitable choice for areas where it will be in contact with pulpal tissue or cementum.

While it does possess adhesive qualities that are beneficial in certain applications, its primary use is in providing a protective base or lining beneath more permanent restorations. This is why it is not typically used for retaining crowns, temporary bonding, or long-term restorations, as those situations require materials with different properties and strength. Hence, its designation as Type three highlights its specific role in supporting other restorative materials while ensuring comfort and protection for the tooth.
