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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial is testing whether the thread design of a dental implant affects how stable it is when placed in the upper back jaw. Adults aged 18-60 who need an implant in that area will be randomly assigned to receive either a double-thread or a triple-thread implant. Stability is measured right after placement using insertion torque and a resonance frequency analysis, with a follow-up check at three months. The goal is to see if one design offers better initial hold, which could influence implant success.

What this could mean

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

Active substance
double-thread dental implant and triple-thread dental implant
What this could lead to
If one thread design proves more stable, it could guide dentists in choosing implants that are more likely to succeed, especially in the upper back jaw.
What could go wrong
This is a small, early-stage study with only 20 participants, so results may not apply to everyone. Individual bone quality and healing can vary, affecting outcomes.

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 20 people

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

Expected to start

Sep 2026

An estimate. Start dates often move.

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.

Ages

20 to 55 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

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

Inclusion Criteria: * Patients aged 20-55 years. * Medically healthy individuals without any systemic disease that affects bone healing (e.g., uncontrolled diabetes, osteoporosis). * Patients requiring dental implants in the posterior maxilla. * Adequate bone volume for implant placement. * Signed informed consent for participation in the study. Exclusion Criteria: * Smokers (due to the potential negative impact on bone healing and implant success). * Pregnant or breastfeeding women. * Patients with a history of radiotherapy or chemotherapy. * Patients with severe periodontal disease. * Individuals with a history of allergic reactions to implant materials.
