About dispensing guns & syringes
An impression dispensing gun holds the cartridge of impression material and presses both parts out together, each cartridge size with the gun made for it. Cartridges come in sizes such as 50 ml and 10 ml. The gun is matched to the cartridge by size and mixing ratio, which makers mark on the gun, for example DS-50 with 1:1 and 2:1. In one published technique a light body material was injected over the abutments with an automatic mixing syringe with a tip attached.
Two-part impression and restorative materials are mixed one of three ways: by hand, through a static mixer, or by a machine that mixes them dynamically. A review calls auto-mixed, cartridge-based materials a notable development, and gives two reasons: it removes the spatulation step and the operator errors that go with it, and it cuts the number of voids in the impression by a factor of four to five against mixing by hand. A cartridge is pressed out with a dispensing gun through a mixing tip, a static mixer fixed to the end of the cartridge.
How mixing tips, intraoral tips, guns and bowls differ
- Mixing Tips — The disposable part: used mixers are discarded and the cartridge is resealed with its original cap.
- Intraoral Tips — Added after the mixer, to reach into the mouth.
- Dispensing Guns & Syringes — The reusable part, chosen by cartridge size and mixing ratio. Material comes out easily through a mixer of the right size; one maker warns that excessive force can rupture the cartridge or break the gun.
- Mixing Bowls & Dishes — For material mixed by hand, where a cartridge and tip are not involved.
What to look at when choosing
Fit: makers' instructions name the tip for each cartridge by colour and size, such as a yellow tip for a 50 ml cartridge and a brown tip for a 10 ml one. Some static mixers carry a built-in metal needle tip of a stated gauge, such as 17 or 19 gauge, for more precise placement.
First material out: makers instruct users to express a small amount onto a pad first, to ensure an even mix of base and catalyst.
Gloves: sulfur from natural latex gloves can contaminate the platinum catalyst of a vinyl polysiloxane and hold up its set, and the end of a mixing tip is one of the things a review names as not to be touched with latex gloves on.
Where the voids come from: a review lists mixing of base and catalyst, loading of the tray or syringe, the syringing itself, and working past the working time.
