Provisional materials are key in the fabrication of temporary fixed restorations to produce a variety of crowns, bridges, and veneers. Although CAD/CAM technology allows for the placement of final restorations in a single visit, provisional materials are still necessary in many circumstances.
No matter which material a clinician decides to use, all provisional materials must preserve and protect the underlying dentition.1 A provisional restoration should seal a tooth while protecting the pulp from bacteria and reducing sensitivity.1 It also maintains the occlusal space and contact points.1
Temporary materials also help seal against bacteria, prevent seepage of intracanal medicaments, insulate pulpal tissue, and reproduce tooth contours.1 Biocompatibility, esthetics, fracture resistance, ease of fabrication, shape and polishability, and a short setting time are all desirable characteristics for provisional materials.2
Traditional temporary materials were manufactured using methyl methacrylate, ethyl methacrylate, or vinyl ethyl methacrylate.2 More modern provisionals are fabricated using bis-acryl materials and CAD/CAM-generated restorations.3 No matter which is used, clinicians have a variety of materials at their disposal. Here, we highlight some of the industry’s provisional materials.
VOCO’s Structur family of bis-acrylic provisional crown and bridge materials meet the demands for every clinical temporary situation. Providing strength for short and long-term stability while delivering the esthetics that patients demand, the Structur provisional materials utilize a 1:1 cartridge mix that results in easy application, less waste, and reliable performance. Known for their long-term color stability, high fracture resistance, and high compressive strength, Structur provisional materials are available in several VITA matching shades.
