Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
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 Results may not be published yet.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.

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 trial tests whether custom-made 3D zirconia barriers can rebuild severely thinned jawbone better than the standard pre-bent titanium mesh. Sixteen people with significant bone loss in the lower jaw will receive one of the two materials during a first surgery, followed by dental implant placement later. The study measures changes in bone height, width, and volume, as well as infection and wound healing. Zirconia may offer better biocompatibility and easier removal than titanium.

What this could mean

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

Active substance
customized zirconia barrier
What this could lead to
If successful, this could offer a more biocompatible and easier-to-use alternative to titanium mesh for rebuilding jawbone, potentially improving dental implant success.
What could go wrong
This is a small early-stage trial with only 16 participants, so results may not apply broadly. Zirconia barriers could still cause infection or wound healing problems.

Study facts

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 16 people

The number the study aims to enrol. It can still change while the study runs.

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

Inclusion Criteria: * Patients are systemically medically free according to the American Society of Anesthesiologists (ASA) considered as ASA I. * Ability to maintain good oral hygiene as evidenced in recall visits. * patients who had a partial or completely edentulous alveolar ridge with apparent 3D defect following teeth loss. * All patients were free from any local or general disease that may interfere with bone healing and had no history of previous grafting procedure at the designated edentulous ridge. * The ridge had to exhibit severe vertical and horizontal (3D) alveolar ridge deficiency with alveolar ridge height less than 7 mm from the alveolar crest to the inferior alveolar canal and width less than 5 mm which was firstly measured by CBCT, or a clinically apparent increase in inter-arch space relative to the adjacent natural teeth. * Pre-operative clinical assessment of soft tissue coverage was done to cover the graft and its membrane, in addition to assessment of occlusion and inter-arch distance should allow for the graft, membrane, implan and the future prosthesis. Exclusion Criteria: * Smoker (\> 25 cigarettes/ day). * Patients undergoing radiotherapy or chemotherapy * Patients having infection or local lesions in the area of surgery. * Patients with diabetes mellitus or bone diseases which may compromise the results. * Patient with poor oral hygiene or active periodontal disease. * Patient with limited mouth opening. * Participation in other clinical trials
