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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial compares two ways to replace missing teeth in people with jawbone loss: using short implants or standard implants with a bone regeneration procedure. Twenty participants are randomly assigned to one of the two treatments. The study measures bone level changes around the implant, patient satisfaction, and how many implants remain in place over time.

What this could mean

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

Active substance
Short implant placement or bone regeneration with longer implants
What this could lead to
If successful, this could show that short implants are a simpler, less invasive option for people with jawbone loss, avoiding the need for bone grafting.
What could go wrong
This is a small, early-stage trial with only 20 participants, so results may not apply to everyone. The bone regeneration group may face more surgical complications.

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.

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: * All the patients with a distal edentulism Kennedy -Applegate Class II in the posterior mandible or maxilla, with residual bone height from the top of the crest to the opposite landmark (the alveolar nerve for the lower and the sinus cavity for the upper) between 5 and 7 millimeters. The bone peak on the last tooth before the edentulous space must be positioned from 2 to 4 mm from the CEJ. (X-ray evaluation by periapical film on a Rinn Holder). * All patients with at least 3 mm of keratinized tissue on the edentulous crest. In case of absence of this prerequisite, three months before the keratinized tissue is augmented by a ephytelium-connective tissue graft harvested from the palate. * Patients with edentulous distal sites Exclusion Criteria: * Heavy smokers (more than 10 cigarettes /day) * Patients with active periodontal disease: full mouth plaque index (FMPI \> 20%) and Full mouth bleeding index (FMBI \> 20%). * Patients with less of 5 mm of bone width. * Patients with systemic conditions or under prescription of medications that contraindicate oral surgery
