<h2 style="text-align:justify">W&amp;H Alegra Contra-Angle Maintenance Guide</h2>

&nbsp;

W&amp;H builds its entire hygiene philosophy around one instrument: the Assistina reprocessing device, which handles internal cleaning and lubrication automatically. But not every practice has one on every op, so this guide covers both the automated route and the manual steps that keep an Alegra handpiece performing between services.

&nbsp;

<h2 style="text-align:justify">Know What Your Model Is Rated For</h2>

&nbsp;

This matters more with Alegra than with most contra-angle lines: standard (non-&quot;T&quot;) Alegra models are approved for automated thermo washer disinfection, while the lighter-weight &quot;T&quot; versions are not, per W&amp;H&#39;s own FAQ. Confirm which you have before running it through a thermo-disinfector.

&nbsp;

<h2 style="text-align:justify">After Every Patient</h2>

&nbsp;

<ol>
	<li>
	Remove the bur and wipe down the exterior of the handpiece.
	</li>
	<li>
	Run the handpiece briefly to clear residual water/spray from internal channels, if your workflow includes this step.
	</li>
	<li>
	If using Assistina, process the handpiece through its automated internal cleaning and lubrication cycle before sterilization.
	</li>
	<li>
	If lubricating manually, use W&amp;H Service Oil F1 per the instructions for use specific to your model.
	</li>
</ol>

&nbsp;

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

&nbsp;

<ul>
	<li>
	Test the push-button chuck&#39;s grip with a pull test on a seated bur; this is the most common early wear point on the range.
	</li>
	<li>
	On LED G models, confirm light output is consistent at your typical operating speed.
	</li>
	<li>
	Check external spray clips and accessories (on non-LED models) for wear or blockage.
	</li>
</ul>

&nbsp;

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

&nbsp;

Alegra straight and contra-angle handpieces are described by W&amp;H as thermo washer disinfectable and sterilizable, but confirm your specific model actually carries the sterilization symbol before processing it, since not every configuration is rated the same way. W&amp;H&#39;s own FAQ is direct on this: your handpiece can be processed via sterilizer only if it carries the relevant sterilization symbol.

			LED Instruments Are Sterilizable Too

			&nbsp;

			Per W&amp;H&#39;s own FAQ, LED instruments with an integrated generator are both sterilizable and thermodisinfectable; you don&#39;t need to treat the light mechanism as a reason to skip standard reprocessing.

&nbsp;

<h2 style="text-align:justify">Monthly / Periodic Care</h2>

&nbsp;

<ul>
	<li>
	Review chuck performance across your full Alegra fleet, not just the units currently giving trouble.
	</li>
	<li>
	Confirm your Assistina (if used) is itself maintained per its own service schedule; it&#39;s doing the lubrication work your handpieces depend on.
	</li>
	<li>
	Rotate handpieces in active use rather than running one continuously while others sit idle.
	</li>
</ul>

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

&nbsp;

<ul>
	<li>
	Store sterilized handpieces in their packaging until ready for use.
	</li>
	<li>
	Keep LED G models&#39; generator components dry between uses; moisture ingress is avoidable with routine care.
	</li>
</ul>

&nbsp;

<h2 style="text-align:justify">Mistakes to Avoid</h2>

&nbsp;

<ul>
	<li>
	Running a &quot;T&quot; model through automated thermo washer disinfection; check the model designation first.
	</li>
	<li>
	Skipping internal lubrication because Assistina isn&#39;t available that day; fall back to manual Service Oil F1 application instead of skipping the step.
	</li>
	<li>
	Assuming a dim LED means a failing generator without first checking motor speed.
	</li>
	<li>
	Ignoring early chuck stiffness instead of testing and cleaning it promptly.
	</li>
</ul>

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

&nbsp;

Can all Alegra handpieces go through a thermo washer disinfector?

No, per W&amp;H&#39;s own FAQ, standard (non-&quot;T&quot;) models are approved for automated thermo washer disinfection, while the lighter &quot;T&quot; versions are not.

Do LED G models need special handling during sterilization?

No, W&amp;H confirms LED instruments with an integrated generator are both sterilizable and thermodisinfectable, the same as non-LED models carrying the appropriate symbol.

What&#39;s the benefit of using Assistina over manual lubrication?

Assistina automates internal cleaning and lubrication consistently, reducing the chance that a busy day results in a skipped or incomplete manual lubrication step.
