About lab vibrators
A mechanical vibrator makes the gypsum mix flow and spread into the impression. How fast it flows and spreads depends on the frequency and amplitude the vibrator is set to.
This shelf holds the bench machines of a dental laboratory: lathes, model trimmers, vibrators, mixers, and casting and polishing units. A cast is a life-size likeness formed from a material poured into an impression. Polishing is the act of making a denture or casting smooth and glossy, usually by friction.
A study of dental laboratories lists finishing crowns, bridges and partial dentures among its noisiest work, and names vibrators, polishing equipment and sandblasters as sources of high sound levels.
How the machines differ
- Lathes — Spins the wheels, cones and buffs used for polishing; the CDC lists lathes among the items to be cleaned and disinfected between patients.
- Lab Vibrators — Shakes the mix into the impression after it has been mixed.
- Mixing Equipment — Blends powder and water, under vacuum, before the mix is poured.
- Electro-Polishing Equipment — Brightens metal by removing a thin layer electrolytically, where a lathe polishes by friction.
- Casting Units — Fills a mould with molten material, where the other machines here shape or finish a solid one.
The shelf also holds model trimmers; no source on our allowed list describes them, so this guide does not.
What to look at when choosing
Air in the mix: the strength, hardness and abrasion resistance of a gypsum cast are affected by the number and size of the voids in it.
Surface after polishing: studies cited in the denture literature put the acceptable roughness of a hard surface in the mouth at no more than 0.2 micrometres.
The CDC reports that dental laboratory technicians can breathe in crystalline silica dust when mixing powders, removing castings from moulds, grinding and polishing castings and porcelain, and blasting with silica sand.
Cleaning between cases: the CDC notes that pressure pots and water baths are particularly susceptible to contamination and should be cleaned and disinfected between patients.
