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 Results may not be published yet.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.

Summary

This study tests whether placing the final abutment once during dental implant surgery, without removing it during healing, reduces bone loss around the implant compared to standard repeated disconnections. Researchers will also measure patient satisfaction and analyze mouth bacteria. The trial involves 32 healthy adults needing implants in the back of the jaw.

What this could mean

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

Active substance
abutment placement procedure
What this could lead to
If successful, this could support a simpler, more bone-preserving approach to dental implants, reducing bone loss and improving long-term implant stability.
What could go wrong
This is a small, early-stage study with only 32 participants, so results may not apply to all patients. The benefits over standard care are not yet proven.

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

Inclusion Criteria: * Healthy partially edentulous adult patients needing at least two implants for the placement of single or consecutive crowns in the posterior mandible or maxilla will be recruited. * These patients should exhibit a plaque index and gingival bleeding index of less than 25%, and have sufficient bone height and width for the placement of dental implants measuring 8 or 10 mm in length and 3.5 or 4 mm in diameter. * Additionally, they must have at least 2 mm of keratinized vestibular gingiva, stable occlusion, and a periodontium in good health Exclusion Criteria: * Edentulous areas requiring bone grafts will be excluded. * Patients with medical conditions contraindicating implant surgery, such as severe bruxism or inadequate oral hygiene. * Pregnant or lactating women, patients undergoing bisphosphonate therapy, those receiving chemotherapy or radiotherapy in the head and neck area, non-compliant patients with incomplete data records, and those who do not attend regular follow-up appointments will also be excluded.
