What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares metal and plastic probes used to measure gum pocket depth around dental implants. Researchers will test 64 adults with single-tooth implants to see which probe type gives more accurate readings. The goal is to improve how dentists monitor implant health and reduce patient discomfort.

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 help dentists choose the best probe material for more accurate gum measurements around implants, potentially improving implant care.
What could go wrong
This is a small, early-stage study with only 64 participants, so results may not apply to all implant types or patients. It focuses on measurement accuracy, not treatment outcomes.

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

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 64 people

The number the study aims to enrol. It can still change while the study runs.

Started

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults (≥18 years) * Presence of at least one single-unit bone-level implant rehabilitated with a screw-retained prosthesis directly connected to the implant (no intermediate abutment) * Implant in function for at least 1 year after prosthetic loading * No pathological bone loss on periapical radiograph (distance from the most coronal rough surface of the implant to the bone crest \< 3 mm) * Ability to understand and sign informed consent * Peri-implant health or mucositis, defined according to the 2017 World Workshop criteria: * Health: no clinical signs of inflammation, lack of profuse (line or drop) bleeding on probing, no increase in probing depth compared to previous records, and no progressive bone loss beyond initial remodeling (\<2 mm). In the absence of previous radiographs, radiographic bone level \<3 mm without bleeding and/or suppuration on probing. * Mucositis: presence of bleeding and/or suppuration on probing, no increase in probing depth compared to previous records, and no bone loss beyond initial remodeling (\<2 mm). In the absence of previous radiographs, radiographic bone level \<3 mm with bleeding and/or suppuration on probing. Exclusion Criteria: * Cement-retained restorations or prostheses that cannot be removed * Systemic antibiotic or anti-inflammatory treatment within the previous 3 months * Pregnancy or lactation * Peri-implant treatment within the previous 3 months * Participation in another clinical trial within the last 30 days
