Why you do not reboot during a crown

The mill, the scanner, and the patient do not care that Windows wanted a restart.

Short answer: Never restart a dental computer while a procedure is in progress. A reboot can interrupt a milling job, lose a scan, drop an image mid-save or disconnect the PMS during charting. The rule: if a computer asks for a restart during clinic hours, defer it and call the HelpDesk; updates belong in a maintenance window.

Why is rebooting during a procedure a problem?

Because the computer in an operatory is part of the procedure. A chairside milling unit may be mid-cycle on a crown. An intraoral scanner may be holding a scan that has not been saved. A sensor session may be about to write an image. A chart note may be half-typed. A restart does not pause these; it ends them. The patient is in the chair, the clinician has committed to a timeline, and the work may have to be redone.

Why does it happen?

Almost always one of three reasons:

  1. A forced update restart. Windows decides the machine has waited long enough and restarts itself, or a prompt appears and someone clicks "Restart now" to make it go away.
  2. A frozen screen. The instinct is to hold the power button. Often the system is busy, not dead.
  3. "Let's try turning it off and on again." A sensible reflex in an office, and the wrong one in the middle of a procedure.

What is the rule?

  • Never click "Restart now" during clinic hours. Choose a later time or dismiss the prompt.
  • Never power-cycle a machine mid-procedure. First finish or safely pause the clinical task.
  • Call the HelpDesk at (954) 639-7049 and say what is frozen, in which room, and whether a patient is seated. See How should a dental practice report an outage?.
  • After the patient leaves, the engineer can decide whether a restart is the right fix.

How does IT prevent forced restarts?

This should not depend on staff discipline alone. Managed IT controls update behavior centrally: updates are staged, installed outside clinic hours, and restarts are scheduled for maintenance windows rather than left to Windows' own timing. See Patching without killing the sensors. Smart Agent and the HelpDesk also watch for machines with pending restarts so they can be handled overnight.

What if the machine is truly frozen?

Give it a short, reasonable wait first. Then call before pulling the plug: a hard power-off risks corrupting open files and, in some cases, databases. The engineer can often see what the machine is doing remotely and tell you whether to wait, how to save work, or when a restart is safe.

What should be posted at every operatory?

A single line: "Computer problem? Don't restart. Call (954) 639-7049. Say the room, the product and whether a patient is seated."

Why is this a clinical matter?

Because IT in a dental office is part of the care pathway. See Dental IT is a clinical issue.

Frequently asked questions

Is it okay to restart a dental computer between patients?

Only if IT has agreed it is safe and no clinical task is pending. Restarts for updates should be scheduled after hours rather than done ad hoc between patients.

How do I stop Windows from restarting during the workday?

Update behavior should be managed centrally by your IT provider, with installs and restarts scheduled in maintenance windows. Call your HelpDesk rather than changing settings yourself.

What should I do if the computer freezes during a procedure?

Do not power-cycle it. Wait briefly, then call the HelpDesk with the room, the product and whether a patient is seated.
