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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether a dental implant with a special lateralized design (Osseotite Certain Prevail) preserves more bone around the implant than a standard version. About 100 adults who need a short fixed bridge to replace missing teeth will receive one of the two implant types. The main question is whether the new design reduces bone loss 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
a dental implant with a lateralized design (Osseotite Certain Prevail) compared to a standard non-lateralized implant (Osseotite Certain)
What this could lead to
If the lateralized design preserves more bone, it could lead to longer-lasting dental implants with fewer complications.
What could go wrong
This is a relatively small trial comparing two similar devices, so differences may be small or not clinically meaningful. Bone loss around implants depends on many factors beyond design.

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

Inclusion Criteria: * patients of either sex and any race greater than 18 years of age * patients for whom a decision has already been made to use dental implants for treating an existing dental condition specifically: a partially edentulous short fixed case of less than 4 implants in the maxilla or mandible; no cantilevers are allowed, but one interior crown may be a pontic * patients must be physically able to tolerate conventional surgical and restorative procedures * patients must agree to be evaluated for each study visit, especially the yearly follow-up visit Exclusion Criteria: * patients with active infection or severe inflammation in the areas intended for the implants * patients with more than 10 cigarette per day smoking habit * patients with uncontrolled diabetes mellitus * patients with metabolic bone disease * patients who have had treatment with therapeutic radiation to the head within the past 12 months * patients in need of allogenic bone grafting at the site of the intended study implant * patients who are pregnant at the screening visit * patients with evidence of severe para-functional habits such as bruxing or clenching * patients with cantilevers and more than one pontic per bridge
