Using a resin-ionomer in guided tissue regenerative procedures: technique and application--case reports.

The purpose of these case reports is to introduce a potential use for a resin-ionomer in guided tissue regeneration. The resin-ionomer is used in a two-fold manner (1) to lute an e-PTFE membrane in place in furcation defects and (2) to act as a barrier itself in furcation and infrabony defects. Clinical observations made in this report indicate that a resin-ionomer barrier may be placed subgingivally without sutures. In addition, the resin-ionomer, given its ability to release fluoride, may serve as a delivery system for local antimicrobial therapy during the initial stages of wound healing. Further studies should be conducted in order to evaluate the potential of the resin-ionomer for the uses described in this article.
