Dental turbines are one of the instruments of dental appliances most used in dentistry. Turbines have multiple uses, as they can be used to remove cavities, perform tooth grinding to prepare crowns and cavities, or polish leftover composite.
In terms of dental turbine connections , we can differentiate two main families:
- Turbines with direct hose connection: Every time we want to connect them to the hose we must screw and unscrew.
- Quick connection turbines: They have an adapter that allows us to connect and disconnect the turbine quickly and conveniently.
Turbines with direct hose connection: Midwest (M4) and Borden connections
Turbines with direct hose connection are connected directly to the dental chair hose. They have the advantage that they are cheaper and do not need to have a coupling or connection. In addition, no air force is lost in the adapter, so if we do not have much air pressure in the cabinet, they may be an option to consider. As against, if we have to plug them and unplug them very often to grease or sterilize them, this will be a more cumbersome process than if they had a quick connection, since every time we will have to fit them in the hose and screw them correctly.
In Europe, most dental equipment uses Midwest hose, so ideally your rotary instrument should be Midwest as well. On the other hand, in America it is very common to use a Borden connection. If you need to connect Midwest hose with Borden turbine, or vice versa, you will need to use an adapter, such as the RMaster adapter.
The modern turbines of the main manufacturers usually incorporate a quick coupling connection that facilitates the connection and disconnection of the turbine. This coupling or link is connected to the hose (either this 4-hole Midwest or two-hole Borden), and is left fixed, being only the turbine that is connected and disconnected from the adapter to lubricate and sterilize it.
Each of the main brands for dental turbines have its quick coupling, but the most widespread coupling, which is becoming a standard is the one from Kavo's Multiflex coupling.
