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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers compare how much bacteria builds up around two attachment systems used to hold implant-supported lower dentures in place: MK1 attachments and standard clip attachments. Seven adults with no teeth receive both types of dentures one after the other, so each person acts as their own comparison. The team collects samples from the denture surface and around the implants at follow-up visits to count streptococci and staphylococci. The goal is to learn whether the attachment design affects bacterial growth, which could guide better denture care.

What this could mean

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

Active substance
Two denture attachment systems: MK1 attachments and conventional clip attachments
What this could lead to
If one attachment type collects fewer bacteria, dentists could choose it to help implant-supported dentures last longer and stay healthier.
What could go wrong
This is a very small study of seven people, so the results may not apply to everyone. It only measures bacteria, not whether dentures actually last longer or feel better.

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 7 people

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

Started

Mar 2026

Expected to finish

Jan 2027

An estimate. End dates often move.

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: * Completely edentulous patients aged 45-65 years. * Medically healthy patients with no systemic conditions affecting implant placement or osseointegration. * Healthy maxillary and mandibular residual ridges covered by firm mucosa. * Adequate mandibular bone volume in the interforaminal region to receive four implants (minimum 4 mm diameter and 12 mm length), confirmed by CBCT. * Class I maxillomandibular relationship with sufficient interarch space for implant-supported overdentures. Exclusion Criteria: * Uncontrolled diabetes mellitus, immune disorders, osteoporosis, or other contraindications to implant therapy. * Parafunctional habits such as bruxism or clenching. * Flabby ridges or oral mucosal diseases. * Severe temporomandibular joint disorders. * History of allergy to denture or implant materials. * Previous radiotherapy to the head and neck region.
