Perma Block is a specially designed, cellulose-based block-out material that is delivered in an easy to use single dose cartridge! Perma Block will adhere to a wet rubber dam, gingival and mucosal tissues and teeth. It will adhere underwater and saliva!
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.
Its heavy body prevents displacement during intraoral pick-up of attachments with auto polymerizing resins. May be used for Laboratory duplication, but not indicated for Laboratory / Indirect Processing of Acrylic.
The single dose cartridge fits into your Centrix or composite gun and may be rotated to any angle for ease of use. This provides a mechanical advantage for easy expressing and placement of Perma Block.
Perma Block is easily contoured or shaped with an instrument, cotton swab, or a wet finger in a rubber glove. Perma Block is easy to remove and clean up. Simply remove large sections or pieces with an instrument. Water and a brush will readily remove any remaining Perma Block material.
