USE OF A RESIN-IONOMER IN GUIDED TISSUE REGENERATION - CASE-REPORTS

The cases presented in this report illustrate: (1) the potential for a fluoride-releasing resin-ionomer (Geristore) to be used as a sealant between an e-PTFE membrane (Gore-Tex) and tooth structure during a gui ded tissue regeneration, and (2) the potential for a resin-ionomer to function as a barrier in guided tissue regeneration. In the first case , the e-PTFE membrane was trimmed to only cover the area to be treated prior to its placement over the lesion. The resin-ionomer was mixed f ollowing manufacturers specifications, placed on four corners of the p re-trimmed membrane and luted into place, In the second case, the resi n-ionomer alone was placed over the lesion, teased off the lesion with a curette while in a semi-set state, and luted into place with freshl y mixed material after it set completely. These cases provide prelimin ary clinical evidence that a resin-ionomer may be used subgingivally f or guided tissue regeneration.
