SpiraPost: Little Metal Fibers Coming Off Post?

spirapost.jpgThe advertisement for Spirapost (Zenith Dental) shows all these little metal fibers coming off the post that are supposed to engage the composite core. This kind of makes sense for retention of the core material. But has anybody tried this technique? Are those little metal fibers sharp and can they puncture a glove? Is the central metal post thick enough and strong enough?

Editors Note:
According to Zenith:
“The innovative new Spirapost PFS (Poly Fiber Strands), exclusively from Zenith Dental, naturally flexes to conform to the shape of the canal, to offer the benefits of a custom fit for all root canal configurations. Due to its unique design, Spirapost is able to adapt to the irregularities of the canal, so it minimizes the removal of tooth material. Non-technique-sensitive and highly esthetic, Spirapost is simply the most advantageous dental post now available.”
