A-Seal is made of PTFE (Polytetrafluoroethylene), a high-quality material used for sutures and membranes. It has the significant advantages of spreading smoothly inside the abutment hole to fill it without creating gaps, preventing shrinkage, and being easy to remove.Because it perfectly fills the abutment hole space without shrinkage, it does not cause odors from saliva.There is absolutely no need for procedures such as using cotton to protect the hexagonal hole, light curing, or heat transferThis can be achieved through a simple process of filling the A-Seal with a PR 17 plugger.For removal, remove the resin from the occlusal surface, then use the removal end of the dedicated PR 17 instrument to push it in and pull, allowing for easy and clean removal.
