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 Results may not be published yet.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.

Summary

This study will test how accurate three different 3D scanners are at creating custom dental attachments for tooth roots. Sixty adults who need these attachments will have their teeth scanned with each scanner, and the fit will be compared. Patients will also report which scanning method feels more comfortable.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

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

Ages

18 to 65 years

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: 1. Patients aged 18-65 years. 2. Endodontically treated teeth requiring intra-radicular attachments. 3. Adequate oral hygiene . 4. Periodontally Compromised Teeth: When some teeth have reduced bone support but can still be maintained as overdenture abutments with proper treatment. Exclusion Criteria: 1. Severely Compromised Remaining Teeth: If the remaining teeth have poor prognosis due to extensive decay or severe periodontal disease. 2. Severe Bone Loss Around Abutment Teeth: If the remaining teeth do not provide adequate support, they may fail early, leading to additional complications. 3. Severe Malocclusion: Where occlusal discrepancies make overdenture placement difficult. 4. Limited inter-arch Space: cann't accommodate the overdenture components. 5 . Poor Oral Hygiene: increase the risk of decay or periodontal issues in retained abutments.
