title: Technique for repair of multiple abutment teeth under preexisting crowns.
abstract: This technique describes a simple procedure for repairing multiple fractured or broken-down abutment teeth under existing crowns. The technique uses a Teflon tape polytetrafluoroethylene (PTFE) as a matrix and separating medium for fabrication of an autopolymerizing composite core material with digital pressure. This technique enables the dentist to solve an emergency clinical situation in a relatively short amount of time, pending further restoration with endodontic treatment and a cast post and core procedure.
