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 Results may not be published yet.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

Summary

This study looked at two methods to widen the upper jaw in adults whose jawbone has fully grown. One method uses small screws anchored in the roof of the mouth, and the other adds tiny bone punctures to help the jaw separate more easily. Twenty-four adults took part, and the results were measured with 3D X-rays to see which approach worked better for correcting a narrow upper jaw.

Inclusion Criteria: 1. Suture maturation stage D or E according to the method of Angelieri et al. (Angelieri F, Cevidanes LH, Franchi L, Goncalves JR, Benavides E, McNamara JA, Jr. Midpalatal suture maturation: classification method for individual assessment before rapid maxillary expansion. Am J Orthod Dentofacial Orthop. 2013;144(5):759-69.) 2. Maxillary transverse deficiency measured using the method of Cantarella et al. (Cantarella D, Dominguez-Mompell R, Mallya SM, Moschik C, Pan HC, Miller J, et al. Changes in the midpalatal and pterygopalatine sutures induced by micro-implant-supported skeletal expander, analyzed with a novel 3D method based on CBCT imaging. Prog Orthod. 2017;18(1):34.) 3. Good oral hygiene (Score \<2 based on the Simplified Oral Hygiene Index (OHI-S)). (Greene JC, Vermillion JR. The Simplified Oral Hygiene Index. J Am Dent Assoc. 1964;68:7-13.) Exclusion Criteria: 1. History of previous orthodontic or orthopedic treatment. 2. History of facial trauma or surgery. 3. Patients with congenital craniofacial malformations or diagnosed syndromes. 4.
