As dental offices get back to business in the new normal, the CDC Guidance states that, whenever possible, Dental Healthcare Practitioners (DHCPs) remain with one patient until the procedure is complete and minimize the practice of exiting and re-entering the operatory in order to provide dental care in parallel to multiple patients seated in different operatories.

The CDC Guidance also states that each time the DHCP enters or exits the operatory, he or she should doff or don PPE, which includes replacing gloves, gowns and protective clothing, swapping out or wiping down eye protection, discarding surgical masks or respirators, and performing hand hygiene.

How can dentists’ practice in the "new normal", follow the CDC’s infection control guidelines, and maintain productivity and patient volume?

The answer is Seat, Treat & Complete.

What is Seat, Treat & Complete?

Seat the patient, administer local anesthetic, go right to work, complete the procedure, exit the operatory. 

  • Buffering with Onset lets you get the patient numb right away and complete the procedure without exiting and re-entering the operatory (Seat, Treat & Complete) reduces treatment time in the operatory by 25%-30%.

  • Seat, Treat & Complete with Onset also cuts in half the cross-contamination events to which you, the dentist, your patients, and your staff are exposed.

  • By limiting your operatory entries and exits to one per procedure, Seat, Treat & Complete also cuts your practice’s PPE consumption by 50% or more.

Seat, Treat & Complete; what is it and how will it help my practice?

Q:  What is Seat, Treat & Complete?

A:  The Seat, Treat & Complete protocol means seating the patient, administering buffered anesthetic, going right to work, completing the procedure, and exiting the operatory.

Q:  Under Seat, Treat & Complete, when do I conduct hygiene exams?

A:  Hygiene checks occur between procedures, after the dentist has completed the procedure in one operatory, before the dentist enters the next operatory.

Q:  What are the most important benefits of Seat, Treat & Complete for the dental practice?

A:  The three most important benefits are:

1) Seat, Treat & Complete using Onset reducing treatment time in the operatory by 25%-30% per procedure.  

2) Seat, Treat & Complete also cuts in half the cross-contamination events to which the dentist, patients, and staff are exposed on a daily basis.

How does Onset improve patient volume even under COVID-19

Watch as Dr. Dwight Simpson discusses how he has been using Onset and the Seat, Treat & Complete method for the last eight year in his practice, and the results.  He describes how treating patients in serial lets him conduct 30% more procedures in a typical day - versus when he treated patients in parallel, regularly switching back and forth between operatories (a practice the CDC now discourages).  He also explains how Onset keeps the office on schedule and reduces stress.

How does Onset make Seat, Treat & Complete possible?

Watch Dr. Mark Hyman describe how this is the most productive way to practice and it complies with the CDC’s infection control guidance!

How does Onset help reduce PPE consumption?

With Seat, Treat & Complete, you complete each procedure without having to leave the operatory.  Watch Dr. Mike Ditolla & Dr. Mic Falkel discuss how staying with the patient saves 50% on PPE consumption, better protects you, your staff and your patients from contamination, and makes your schedule much more productive.

How does Onset reduce potential cross contamination events?

Watch Dr. Bill Yant describe how each potential entry and exit of the operatory uses an additional set of PPE and increases the risk of cross-contamination. Using Seat, Treat & Complete Dr. Yant has increased his practice’s efficiency and freed up time in his schedule.

Practicing more productively in the Covid-19 era using Seat, Treat & Complete.

Watch and listen to a conversation between practice management consultant Cindy Ishimoto and Dr. Mic Falkel about practicing in the Covid-19 era using Seat, Treat & Complete to increase productivity, even while staying in compliance with the CDC’s new guidance on infection control.
