A novel technique for the direct fabrication of fixed interim restorations.

This article describes an alternative technique for the fabrication of interim restorations. A thermoplastic, vacuum-formed template and translucent vinyl polysiloxane material are combined in the waxed diagnostic cast to fabricate a matrix in which the interim material can be placed. With this matrix, a variety of materials, such as dual-polymerized or light-polymerized resins, can be used in a predictable way. The major advantage of this technique is that it allows for the fabrication of accurate restorations with excellent:reproduction of surface anatomy and for alterations of the tooth shape with light-polymerized materials.
