Extraoral Dental Suction Systems for Practices - Cattani's Aspi Aero 25

Extraoral Dental Suction Systems -What are they & how do they work?

What is an Extraoral Dental Suction System?

We are in an unprecedented, and perhaps previously unimaginable, situation. We little to no guidance or magic wand sadly at present and it appears that this will not change and now with a date given for dental practices in the UK to potentially open, and we are happy to give my engineer’s opinion on possible steps going forward of ways to support dental practices lowering the risk in returning to working in surgery. See Jim’s full report here 

As engineers and dental equipment specialists, we have been considering the options for equipment; one of the options is to consider an ‘extraoral’ suction unit. These are sometimes known as an air extraction or aerosol reduction unis.

As we know aerosols are generated during dental procedures with a high-speed handpiece and an ultrasonic scaler, and as such in this current climate are of great concern in our reopening of surgeries. The aerosol emerging from the mouth of the patient consists of splashes of the spray mist rebound and droplets containing cooling water, saliva, blood, microorganisms, bacterias, and viruses.

Aerosols are differentiated based on particle size: spatter, droplet, and droplet nuclei.
• Spatter (> 50 µm), being the larger particle, will fall until it contacts other objects (e.g., floor, countertop, sink, bracket, table, computer, patient or operator).
• Droplets (≤ 50 µm) remain suspended in the air until they evaporate, leaving droplet nuclei that contain bacteria related to respiratory infections.
• Droplet nuclei (≤ 10 µm) can contaminate surfaces in a range of three feet and may remain airborne for 30 minutes to two hours. If inhaled, the droplet nuclei can penetrate deep into the respiratory system.

In dental settings, 90% of the aerosols produced are extremely small (< 5 µm).

The Extraoral Suction System is a chairside mobile unit, that incorporates high-velocity air excavation, placed near the patient which gathers droplets and draws them through a HEPA filter, and safely ventilates them back into the room, or externally where feasible. Each unit on the market offers a different shape funnel, and this is positioned close to the oral cavity and used in combination with your regular HVE.

An Extraoral Suction System from world leaders in air technology Cattani

We are an authorised supplier for Cattani in the UK and are excited to announce the release of its new extraoral suction system, the Aspi Aero 25.

One key point to consider if you are looking at extraoral suction units is that some on the market can only run for a limited time and then need a period to cool down. Italian manufacturers Cattani, have developed the Aspi Aero 25 which can run continuously.  The unit is equipped with a new generation Uni Jet 75 1AC twin vane motor and is continuously rated and will work all day, protecting your patients and team during short and longer treatments. Cattani are known around the world for producing some of the most efficient and reliable suction motors and so it is no surprise to see this join their family of products.

HEPA – High-Efficiency Particulate Arrestance – has been the gold standard in the medical industry for many decades. HEPA filtration is well known and with size 0.3 micron, or smaller, will remove at least 99.97% of particles and produce no harmful by-products. The Aspi has a moisture separator that protects the high-performance H14 HEPA filter from moisture ingress and filter efficiency compromise.

A customer of mine recently was looking for a solution but was conscious that he would not be able to duct outside, as his practice was in a period listed building in the UK. The Aspi Aero 25 can be vented safely externally or internally (in line with ISO requirements).

Air purification is another good alternative. however the costs for a ‘tried and tested’ quality unit tend to be higher. Extraoral suction systems do seem well priced and provide a excellent option during this time when the internet seems flooded with new inventions and suppliers all trying to offer ways to help you return to the ‘new’ normal.

Kind Regards

Jim, Kirsty and all the team
