A one-appointment procedure for cast post and core restorations.

An accelerated method of using a light-cured acrylic resin and rapid burnout for casting a direct-pattern post and core restoration is presented. Light-cured acrylic resins are an alternative to chemically cured acrylic resins or indirect patterns formed from an elastomeric impression. The procedure can eliminate an appointment for the patient in the fabrication of the post and core restoration and can be completed in most dental offices with minimal laboratory facilities. Chair-side time is saved because of the elimination of one provisional restoration when two are usually required. Laboratory time is also saved because of the decrease in investment setting and burnout time.
