Frasaco Strip Crowns have a smooth inside finish that requires no polishing after crown shell is stripped off. Tapered toward the neck to fit tooth perfectly and adapt to gingival rim. Thin, easy-to-cut celluloid is resistant to tearing, yet flexible. Antistatic treatment aids handling. Use as molds for temporaries or for shaping the final layer in a multi-layer restoration. Anterior crowns can be cut for use as matrices for corners and edges. Posterior crowns can be cut to create a precise anatomical matrix for permanent two-surface composite restorations.
