Dental Equipment Preventative Maintenance: Operatory (Part 2 of 3)

Posted by David Brunker - VP of Service on Nov 14, 2019 10:08:39 AM

When it comes to dental equipment, preventative maintenance is a must. Equipment must be properly cared for to keep instruments working at peak performance for as long as possible, but also you—as the health care provider—and your patient must be kept safe from infection. Through preventative maintenance tasks daily, weekly, monthly and annually, your dental practice lessens the chances of unexpected equipment failures resulting in downtime, as well as more importantly, safety concerns. 

As you know, managing a dental office and the necessary dental equipment maintenance tasks is often overwhelming. Our goal here is to simplify things in a short three-part blog series covering dental equipment preventative maintenance specific to sterilization, operatory, medical gas and IT tasks.

Operatory Preventative Maintenance

Does your process have a well-outlined document outlining all maintenance tasks in the operatory?  With patients coming and going and the business of the day, it is important that these are clearly visible and imperative they are performed well to minimize contamination and infection and to keep equipment running at peak performance. Review these tasks with your team often, and make sure to revise them as necessary. In doing so, you will find they become second nature.
