A Suggested Solution for Endodontic Provisional Challenges

The provisional restoration must provide a seal that prevents the exchange of fluids from the oral cavity to the canal space, while maintaining any medications within that space. Anderson and others have shown that IRM coronal restorations had significant leakage after seven days. This leakage was determined to be extensive under thermal stress. Galvin and others conducted a study wherein the resins tested “all produced coronal seals superior to those produced by IRM.” Efficient replacement and removal of the provisional restoration is essential. The restorative material must be prevented from entering the canal space. By using materials common to the dental office, cost is reduced.
