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 Results may not be published yet.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.

Summary

This study looked at how well full-arch dental restorations made from monolithic zirconia hold up when placed using a special digital scanning tool called a scan ladder. Twenty-five completely edentulous patients received implant-supported restorations and were followed for one year to check for any mechanical problems or failures. The goal was to see if this digital workflow leads to fewer complications.

What this could mean

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

Active substance
scan ladder (horizontal scan body device)
What this could lead to
If successful, this approach could improve the fit and durability of full-arch dental implants, reducing the need for repairs or replacements.
What could go wrong
This is a small, retrospective case series with only 25 patients and a short 1-year follow-up, so results may not apply broadly. Mechanical complications like fractures or loosening are possible.

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: * \- Any completely edentulous patient (mandible) with an old satisfactory denture requiring an implant-supported restoration. * Patients aged from 40 to 70, able to sign an informed consent will be considered eligible for this trial. * Implant sites must allow the placement of four implants. * Non- heavy Smokers will be included (smoking up to 10 cigarettes/day) * In case of post-extractive sites, they must have been healed for at least 3-month before being treated in the study. * Patients with no systemic condition that may interfere with implant placement (e.g., Immunosuppressed or immunocompromised patients, patients under treatment of intravenous amino-bisphosphonates) Exclusion Criteria: * \- Patients with poor oral hygiene and motivation. * Pregnancy or nursing. * Drug abusers. * Psychiatric problems or unrealistic expectations. * Patients with infection and or inflammation in the area intended for implant placement. * Patients participating in other studies, if the present protocol cannot be properly adhered to. * Patients with signs of hyperactive muscles.
