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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 tested whether narrow dental implants work as well as standard-sized implants placed with bone regeneration in people with narrow jawbone in the back of the mouth. Thirty adults with a ridge width between 5 and 6.5 mm received either a 3.0 mm narrow implant or a 4.0 mm standard implant plus bone graft. Researchers measured bone levels around the implant and asked about discomfort and willingness to repeat the procedure.

What this could mean

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

Active substance
dental implant (narrow diameter 3.0mm or standard diameter 4.0mm with guided bone regeneration)
What this could lead to
If successful, narrow implants could offer a less invasive option for people with limited jawbone width, avoiding the need for additional bone grafting.
What could go wrong
This is a small completed study with only 30 participants, so results may not apply to everyone. Both implant types carry risks like infection or implant failure.

Study facts

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.

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

Inclusion Criteria: Patients: * 18 years old * Healthy periodontal status (absence of generalized probing pocket depth (PPD) \<4mm) * Oral hygiene levels (FMPS \<20 and FMBS \<20) Site: * Ridge width of \>5mm and \<6.5mm and minimum bone height of 10mm prior evaluation on a CBCT scan * Presence of antagonistic natural tooth or fixed prosthetic restoration * Presence of adjacent teeth * One maxillary or mandibular premolars * Minimum of 3mm of keratinized tissue over the bone crest (20) * Bone regeneration within the limits of the prosthetic restoration. Implants: * Unitary prosthesis * Screwed retained restorations Exclusion Criteria: Patients * Presence of active chronic or aggressive periodontal disease * Presence of systemic disease which contraindicate surgery (patients with an ASA ≥ 3) * Drugs or medications which may alter the results (chronic intake of analgesic medication) * Smokers (\>10cig/day) * Pregnant women * History of head and neck radiotherapy. Site * Anterior area (from 1.3 to 2.3 and from 3.3 to 4.3) and molar area * Previous guided bone regeneration * Location where there is not sufficient restorative space (mesio-distally \<8mm for every restoration unit and \<5mm from the bone crest to the antagonist) * Implant dehiscence of more than 2/3 of the implant. Implant * Implants which cannot be restored with a screwed restoration * Implants which doesn't reach a manual implant stability * implants which after placement doesn't reach a favourable position according to the restoration.
