Plunger syringes designed to introduce impression materials under high pressure during dental procedures. These devices typically consist of a barrel (e.g., octagon shaped), a screw-type plunger, and a threaded tip to attach a blunt needle; some other syringes are all-plastic disposables. Impression-material dental syringes are used to obtain a negative copy (i.e., impression) of dental or related structures (e.g., dental arch), typically for construction or assembly of a fixed restoration or denture.
