Save time and money with frasaco strip crowns, achieving optimum efficiency in no time.
Even for multiple layer technique, strip crowns can be used as matrix to shape the final layer.
Frasaco strip crowns are elastic, thin and easy to cut celluloid crowns. In the transparent execution they are light-transmissive for polymerization light. They are used as moulds for creating temporary restorations on preparations and as matrices for restoration of corners and edges. They are placed without problem using any conventional material for temporary restorations. A strip crown in the required size and shape is adjusted to the cervical area and the gingival margin with a crown scissors. Prior to placement, ensure that strip crown and preparation are clean and dry. Fill the strip crown with temporary filling material and place it. Strip crowns can be used as matrices when restoring corners and edges - also when using composites. When doing so, cut out that section of the strip crown corresponding to the part of the tooth being restored, allowing for the strip crown to overlap the margins of the cavity. Fill the matrix with the definite filling material and press it into place. Remove the matrix after the filling material has set. Should strip crowns remain on a tooth for a few days, please make sure that their gingival edge is no deeper than 1 mm inside the sulcus to avoid possible traumatisation of the marginal periodontium. Under no circumstances should strip crowns remain in the mouth for longer than 30 days.
