<h2 style="text-align:justify">An Engineered Number, Not a Guarantee</h2>

&nbsp;

Bien-Air states the NOVA line offers double the service life of its previous generation, thanks largely to its stainless-steel build and Cylkro gear design. That figure describes what the engineering makes possible, not what happens automatically regardless of how the instrument is treated. A NOVA 1:1 reprocessed casually will fall well short of it. This guide is really just the detail behind closing that gap.

&nbsp;

<h2 style="text-align:justify">Same-Day Basics</h2>

&nbsp;

<h3 style="text-align:justify">Right After the Patient Leaves the Chair</h3>

&nbsp;

<ul>
	<li>
	Disconnect the handpiece from its motor
	</li>
	<li>
	Remove the bur, leaving the chuck released rather than clamped shut on nothing
	</li>
	<li>
	Begin cleaning promptly rather than letting residue sit and dry
	</li>
</ul>

&nbsp;

<h3 style="text-align:justify">Before It Goes Back Into Rotation</h3>

&nbsp;

<ul>
	<li>
	Complete the full clean, disinfect, lubricate, and sterilize cycle, not a partial version of it
	</li>
	<li>
	Confirm the chuck locks a test bur securely before returning the handpiece to your tray setup
	</li>
</ul>

&nbsp;

<h3 style="text-align:justify">Cleaning: Manual or Automated</h3>

&nbsp;

Bien-Air&#39;s contra-angle line supports two validated cleaning paths, and which one fits your practice depends mostly on what equipment you already have.

&nbsp;

<h2 style="text-align:justify">Manual Cleaning</h2>

&nbsp;

<ol>
	<li>
	Clean under running water below 38&deg;C (100&deg;F).
	</li>
	<li>
	Use a soft brush to remove visible debris from external surfaces and accessible openings.
	</li>
	<li>
	Spray internally and externally with Spraynet, holding the tip downward and protecting the connection point with an absorbent cloth.
	</li>
	<li>
	Dry thoroughly before moving on to disinfection.
	</li>
</ol>

&nbsp;

<h2 style="text-align:justify">Automated Cleaning-Disinfection</h2>

&nbsp;

Devices marked with the washer-disinfector pictogram can go through an automated cycle instead, following the washer-disinfector and detergent manufacturer&#39;s own validated parameters. This is generally the more consistent option for practices processing a higher daily volume of instruments.

&nbsp;

<table align="center" border="0" cellpadding="1" cellspacing="1" style="width:900px">
	<thead>
		<tr>
			<th scope="col">
			&nbsp;Never do this

			&nbsp;

			Never place the NOVA 1:1 in an ultrasonic cleaner. This applies to the handpiece itself, regardless of which cleaning path you choose.
			</th>
		</tr>
	</thead>
	<tbody>
	</tbody>
</table>

&nbsp;&nbsp;

<h2 style="text-align:justify">Disinfection</h2>

&nbsp;

<ul>
	<li>
	Surface disinfectant, applied per that product&#39;s own instructions, without immersing the instrument
	</li>
	<li>
	Thermal disinfection, if you&#39;re using the automated washer-disinfector path
	</li>
</ul>

&nbsp;

<h2 style="text-align:justify">Lubrication: The Twice-a-Day Rule</h2>

&nbsp;

Lubricate with Lubrifluid before every sterilization cycle, and at least twice a day regardless of patient volume.

&nbsp;

<ol>
	<li>
	Remove the bur.
	</li>
	<li>
	Insert the Lubrifluid nozzle into the back of the instrument.
	</li>
	<li>
	Spray for approximately 1 to 2 seconds, holding the tip downward over an absorbent cloth.
	</li>
	<li>
	Run the handpiece briefly with a bur inserted to clear surplus lubricant before sterilizing.
	</li>
</ol>

&nbsp;

<table align="center" cellspacing="0" style="width:900px">
	<thead>
		<tr>
			<th scope="col">
			Why this specific rule matters for the NOVA 1:1

			&nbsp;

			The Cylkro gear set is one of this handpiece&#39;s defining durability features, but gears designed to reduce friction still need actual lubricant reaching them consistently. Skipping the twice-daily minimum is one of the more common ways practices quietly undercut the NOVA&#39;s engineered lifespan.

<h2 style="text-align:justify">The Anti-Retraction Valve Deserves Its Own Mention</h2>

&nbsp;

The NOVA 1:1 includes a sterilizable anti-retraction valve, designed to minimize backflow of fluids from the oral cavity into the dental unit&#39;s hoses. It goes through the same reprocessing cycle as the rest of the handpiece rather than a separate routine, but because it&#39;s a hygiene-critical component, give it a specific visual check during cleaning rather than assuming it&#39;s fine simply because the rest of the handpiece looks normal.

&nbsp;

<h3 style="text-align:justify">Storage and Extended Downtime</h3>

&nbsp;

<ul>
	<li>
	Store in a dry, dust-free environment between uses
	</li>
	<li>
	Before returning a NOVA 1:1 to service after an extended period of disuse, run it through a full clean-disinfect-lubricate-sterilize cycle rather than assuming it&#39;s still ready
	</li>
	<li>
	Check the chuck and push-button function after any extended storage period, since seals and lubricant residue can behave differently after sitting unused
	</li>
</ul>

&nbsp;

<h3 style="text-align:justify">A Short List of Avoidable Mistakes</h3>

&nbsp;

<ul>
	<li>
	Skipping the twice-daily lubrication minimum on quieter days
	</li>
	<li>
	Using an ultrasonic cleaner
	</li>
	<li>
	Sterilizing an instrument that hasn&#39;t been properly cleaned and dried first
	</li>
	<li>
	Leaving the handpiece in the sterilizer after the cycle finishes
	</li>
	<li>
	Treating the anti-retraction valve as maintenance-free because it&#39;s sterilizable
	</li>
	<li>
	Assuming a handpiece that&#39;s been in storage for weeks is ready to use without reprocessing
	</li>
</ul>

&nbsp;

<h2 style="text-align:justify">What Actually Extends the Lifespan Here</h2>

&nbsp;

Two things matter more than anything else for a NOVA 1:1 specifically: hitting the twice-daily lubrication minimum without exception, and giving the anti-retraction valve and chuck a genuine visual check at every cycle rather than a cursory glance.

<h3 style="text-align:justify">Frequently Asked Questions</h3>

&nbsp;

Do I need to lubricate a NOVA 1:1 differently than a NOVA 1:5?

The core lubrication method with Lubrifluid is the same across Bien-Air&#39;s range, though always confirm the correct nozzle attachment for your specific model before applying it.

&nbsp;

Can I run the NOVA 1:1 through our washer-disinfector along with turbines?

Only if the specific NOVA 1:1 unit is marked with the washer-disinfector pictogram. Check this before assuming compatibility, since not every configuration supports the automated cycle.
