What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tested whether using a digital face scan to position a dental model saves time and reduces material removal when fitting a single crown, compared to digitizing a conventional articulator mount. Thirty-three adults needing a crown on a molar participated. The goal was to see which method leads to fewer adjustments during the crown delivery appointment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to faster and more accurate dental crown placements, reducing chair time and improving restoration durability.
What could go wrong
This is a small, completed trial with 33 participants, so results may not apply to all dental practices or patient types. The benefits of digital methods may be modest.
