PerfectIM® Systems offer accurate final impressions of subgingival margins without use of retraction cord, gingival excision or application of hemostatic agents. This two-step vinyl polysiloxane impression system eliminates the time consuming task of packing retraction cord and therefore any possible posttraumatic discomfort. Because these materials are hydrophobic, they will displace fluids. These materials are cartridge dispensed, thixotropic (except for Final Wash and SnoWhite™), radiopaque, resistant to fluid absorption, tasteless and odorless. They provide excellent dimensional stability and are immersible in aqueous disinfectants. A range of working/setting times and viscosities are available for any impression procedure.
