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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two ways of taking digital impressions of dental implants in people with no teeth: a professional intraoral scanner and a mobile phone-based system. Researchers will check how accurate each method is and how long it takes. The goal is to see if a simple phone can do the job well enough to save time and money.

What this could mean

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

Active substance
Photogrammetry device (intraoral or mobile-phone-based)
What this could lead to
If successful, this could show that a simple mobile phone can replace expensive intraoral scanners for implant impressions, making dental care more accessible and efficient.
What could go wrong
This is a small, early-stage study with only 42 participants. The phone-based method may not be accurate enough for all cases, and results may not apply to everyone.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will consist of adult completely edentulous patients who have been rehabilitated with implant-supported complete-arch prostheses. Eligible participants will present with a fully edentulous arch restored by at least four osseointegrated dental implants and will be recruited from patients seeking prosthodontic treatment and follow-up care at the study center. All participants will undergo complete-arch implant scanning using both an intraoral photogrammetry system and a mobile-phone-based photogrammetry system for comparative evaluation of scan accuracy and chairside acquisition time. Only patients meeting the predefined inclusion criteria and providing written informed consent will be enrolled.

Ages

18 to 50 years

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

Inclusion Criteria: * Adults aged 18 years or older. * Completely edentulous patients rehabilitated with implant-supported complete-arch prostheses. * Presence of at least four osseointegrated implants in the edentulous arch. * Patients able to undergo digital implant scanning procedures. * Patients willing to participate and provide written informed consent. Exclusion Criteria: * Patients with unstable or failed implants. * Presence of peri-implant disease, active oral infection, or significant soft-tissue inflammation around the implants. * Inadequate access for placement of photogrammetry scan bodies or markers. * Patients with conditions that prevent proper scanning procedures (e.g., inability to maintain mouth opening or remain still during data acquisition). * Patients requiring immediate implant placement or immediate loading protocols. * Patients unwilling or unable to provide informed consent. * Incomplete clinical records or inability to complete all study procedures.
