Some useful ways to pick the best portable dental unit

At first it may seem daunting to try and choose between the various brands of self contained portable dental turbine units available. Prices can vary widely with some seemingly too good to be true to even higher priced units not always being clear on what and how well they work. The purpose of this article is to simplify the purchase decision and explain some of the mechanical features and what to look for when comparing different models of portable dental units for your office or portable dentistry.

 

Look for these specific features when evaluating a portable dental delivery system:

High Grade Dental air Compressor oil free and Vacuum Pumps – Higher quality pumps are made with greater precision and the dynamic balancing of the motors and piston will make them run smoother. This smoother operation is the key to beginning with proper construction to eliminate vibration at its source.

 

Engineered Isolation Mounts – The best way to mount pumps requires not only stable and secure connection to keep the pumps from moving around but also need to eliminate transfer of vibration from the pumps to the chassis. Rubber mounts do a fine job of securing the pump but don’t do very well at absorbing vibration. Improved dynamic mounting is higher quality and eliminates a high percentage of vibration.

 

Compressed Air and Handpiece Performance

Don’t be tricked into using horsepower to try and compare models. Unfortunately, horsepower ratings have a wide range of latitude and marketing companies have used the HP rating to trick many consumers into believing one model is more powerful than another. This is often seen in electric hand tools sold in the big box stores. The best way is to find out if the system you are evaluating can adequately run common brands of dental turbine handpieces for an extended period without pressure dropping.

 

Amalgam Separation – If you will be using the portable dental unit for restorative procedures such as removing old amalgam fillings, the suction system will need the ability to use an amalgam separator. This can require the use of an amalgam separator that the unit can be purged through to collect the heavy metals. To meet state and EPA regulations, the amalgam separator must have been tested and approved by a certifying agency. Verify that the portable model you use provide a certified separator option.

 

Nitrous Oxide scavenging – In office use of a self-contained dental unit often will require the ability to use the portable dental suction to connect to the nitrous patient mask to scavenge off the excess gas. Check to ensure that the portable dental system has the optional capability to be used for nitrous exhaust scavenging.
