As restorative dentists, we are faced everyday with
decisions about which impression materials and techniques should be used when
restoring teeth. The challenge becomes bigger when the patients present with
open gingival embrasures, the dreaded “black triangles”, which tops the list of
dentist frustration while taking the impression and after preparation of veneers,
crowns, bridges, etc. The technique described offers an option to avoid
problems related to impressions locking in gingival embrasures and tearing on removal.
