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 guided 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 following manufacturers specifications, placed on four corners of the pre-trimmed membrane and luted into place. In the second case, the resin-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 freshly mixed material after it set completely. These cases provide preliminary clinical evidence that a resin-ionomer may be used subgingivally for guided tissue regeneration.
（1）在引导组织再生过程中，含氟树脂离聚物（Geristore）有潜力用作电子聚四氟乙烯膜（Gore-Tex）与牙体组织之间的封闭剂；（2）树脂离聚物有潜力在引导组织再生中起到屏障作用。在第一个病例中，电子聚四氟乙烯膜在覆盖病损区之前被修剪，仅覆盖待治疗区域。按照制造商的规格混合树脂离聚物，将其放置在预先修剪好的膜的四个角上并粘结就位。在第二个病例中，仅将树脂离聚物放置在病损区上，在其处于半凝固状态时用刮匙从病损区刮下，待其完全凝固后用新混合的材料粘结就位。这些病例提供了初步的临床证据，表明树脂离聚物可用于龈下引导组织再生。
