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 Results may not be published yet.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.

Summary

This trial tests two ways of connecting a two-piece obturator—a prosthetic device that fills the space left after removing the upper jaw—in people who have had a complete bilateral maxillectomy. Each participant tries a magnet connector for three months, then switches to a dowel pin connector for another three months. The study asks whether one connector is easier to handle, stays in place better, and feels more stable, and also measures chewing efficiency with standardized test units.

What this could mean

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

Active substance
Two-piece obturator with either a magnet or a dowel pin connector
What this could lead to
If one connector proves better, it could guide choices for more comfortable and functional prostheses after maxillectomy surgery.
What could go wrong
This is a small crossover study with only 10 participants, so results may not apply to everyone. Individual anatomy and healing could affect outcomes.
