Convenient. Saves Chairside Time. No mixing, no curing, no setting, no working times required.

Material is immediately placed, used and is easy to remove.


Perma Block is used to block out undercuts associated with large gingival embrasures, implant bars, precision attachments, or fixed partial denture pontics during impression taking procedures.
