A technique report on the in situ application of Atrisorb as a barrier for combination therapy

This article describes a novel technique in which Atrisorb (Atrix Laboratories) is applied in situ as a barrier over a demineralized freeze-dried bone allograft on roots treated with citric acid. Follow-up reentry at 4.5 months demonstrated the effectiveness of this procedure. A rationale for in situ barrier application is presented.
