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 This study
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
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 Results may not be published yet.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.

Summary

Researchers compare two methods for replacing a missing front upper tooth with an implant right after extraction. One method, the Socket-Shield technique, leaves a thin piece of the tooth root in place to help protect the jawbone and gums. The other method uses the standard approach without preserving that root fragment. The trial measures changes in bone thickness, implant success, gum appearance, and patient satisfaction in about 48 adults.

What this could mean

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

Active substance
Socket-Shield technique for immediate dental implant placement, which preserves a piece of the tooth root to protect the surrounding bone and gum
What this could lead to
If it works, the Socket-Shield approach could help people keep more jawbone and a natural-looking gum line after a front tooth implant.
What could go wrong
The trial is small, with about 48 people, and it only looks at front upper teeth. The preserved root fragment could cause problems, and results may not apply to other teeth or to people with gum disease.

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 48 people

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: * Age: 18 to 65 years old; * Good general health, able to tolerate oral implant surgery, with no absolute surgical contraindications (ASA I or II); * Clinical diagnosis of an unrestorable maxillary anterior tooth, suitable for immediate implant placement; ④ Periodontal tissues are basically healthy, with no obvious active infection in the apical area; ⑤ No obvious root fracture on the labial/buccal side or severe mobility preoperatively; radiographic evaluation confirms that the bone volume in the surgical site meets the requirements of the protocol; ⑥ Willing to accept randomization and standardized follow-up, and has signed the Informed Consent Form; ⑦ Able to provide complete intraoral photographs, CBCT (Cone Beam Computed Tomography) scans, and follow-up data. Exclusion Criteria: * Presence of severe systemic diseases that may affect the surgery or healing, or current use of related medications such as bisphosphonates; * Severe periodontal disease or uncontrolled poor oral hygiene; * Obvious inflammation in the apical area of the affected tooth, or pathological root resorption; ④ Abnormal occlusal relationship, obvious bruxism, or inability to establish a stable restorative occlusion; * Pregnancy or lactation, or unsuitability for radiographic examination; ⑥ History of previous surgery or radiotherapy affecting the bone volume or soft tissues in the target area, which the investigator deems would seriously interfere with the evaluation; ⑦ Expected inability to complete the follow-up, or refusal to comply with the study requirements.
