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 Results may not be published yet.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
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study looked at 40 adults aged 35–55 with a history of periodontitis (gum disease) who needed a dental implant. Each received one of two implant surface types: sandblasted acid-etched or plasma-sprayed. Researchers measured bone loss around the implant and gum health over one year. The goal was to see which surface better preserves bone and gum tissue.

What this could mean

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

Active substance
Dental implant with either sandblasted acid-etched surface or plasma-sprayed surface
What this could lead to
If one surface works better, it could help dentists choose the right implant for people with gum disease, possibly reducing bone loss around the implant.
What could go wrong
This is a small, completed study with only 40 participants. Results may not apply to all patients, and the one-year follow-up is too short to know long-term effects.
