Dentapreg® SFM is a fiber-reinforced composite (FRC) strip pre-impregnated with light-curing resin. It is indicated for splinting of teeth in situations where no tooth preparation is necessary, including periodontal and post-traumatic stabilization and orthodontic retention. An entire line of Dentapreg materials covers additional indications. Dentapreg® SFM strips consist of multi-directional braided fibers and are 2 mm wide, 0.2 mm thick and 60 mm long. Each strip is individually packaged to protect it from exposure to light. Clinical procedure involves using a total-etch bonding system on the teeth to be splinted; the strips must always be covered with at least one layer of a flowable composite. Each box includes three strips, a Light Save Box and instructions. Shelf life is three years. Dentapreg® SFM was used by 27 consultants in 162 applications. It received a 93% clinical rating.

Product Features

Dentapreg® SFM offers very good pliability that aids in placement and adaptation to the teeth. Having the strip pre-impregnated with resin eliminates a step chairside and makes the product convenient to use. The resin in the strip is sensitive to ambient light, allowing limited working time during placement. Dentapreg® SFM strips are long enough for most clinical situations, and it is easy to shorten with regular scissors. A slight tackiness of the resin helps hold it in place during adaptation. The narrow strip creates a splint that is not excessively bulky and blends well with the teeth. Seventy-eight percent of consultants found Dentapreg® SFM to be better than other fiber reinforcement materials they had used, and 19% found it to be equivalent. Eighty-nine percent of consultants would switch to Dentapreg® SFM and 96% would recommend it to a colleague.

Clinical Tips

  • Completely cover the strip with composite to avoid exposing the fibers during finishing.

  • Protect from ambient light to avoid premature curing and loss of pliability.

  • Adapt strip to teeth with an instrument and tack cure in sections with a 2 mm curing tip.

  • Use dental floss for adaptation interproximally.
