Iso-Form Temporary Crowns are available in both molar and premolar sizes. They provide a positive contact point with adjacent teeth, allowing the use of dental floss and other oral hygiene procedures during the period of temporization. The smooth, burnished surface of the crown gives good compatibility with gingival tissues.

Iso-Form temporary crowns have an anatomic contour and occlusal surface. The crown margin is constricted, and when placed over the prepared tooth will stretch to closely conform to the preparation margin. The crown margin is easy to burnish and can be quickly modified to conform to the tooth preparation.

The crowns are made from a high purity tin-silver alloy that is soft and ductile. This not only gives Iso-Form crowns their particular degree of ductility, but also the advantage that a crown can be stretched or burnished to alter the shape. The accurate anatomy of these crowns and their ability to automatically stretch to fit the preparation margins make them quick and easy to place.


Special Applications
Some crown preparations for posterior teeth involve minimal occlusal reduction. In these cases, the Iso-Form crowns are easily adapted to the reduced occlusal space to harmonise with the bite, while still retaining the strength of the metal alloy supported by the acrylic relining.

Teeth prepared for full coverage crowns may often have short clinical crowns. Iso-Form temporary crowns can be useful for these patients, as the number of sizes available combined with the ductility of the tin-silver alloy allows quick crown adaptation to fit the preparation.
