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 This study
Running, but no longer taking on new participants.
Completed
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks back at dental implant cases to see if bone-related conditions—like vitamin D deficiency, calcium problems, or kidney disease—make implant failure more likely. Researchers will compare 192 failed implants with successful ones from similar patients. The goal is to understand how local and systemic bone health factors influence implant survival and peri-implantitis.

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 bone health problems are confirmed as risk factors, dentists might screen patients for these issues before placing implants to improve success rates.
What could go wrong
This is an observational review of past cases, so it can show links but not prove cause and effect. Results may not apply to all patients or implant types.

This is an AI summary of the original study and may miss details. Read our disclaimer.
