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 Results may not be published yet.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
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether a customized healing abutment made of PEEK material can guide gum tissue healing after immediate implant placement in back teeth. Twenty healthy adults with non-restorable posterior teeth received implants with either a customized PEEK abutment or a standard one. Researchers measured gum height, width, and volume to see if the customized design improved soft tissue outcomes.

What this could mean

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

Active substance
customized PEEK healing abutment
What this could lead to
If successful, this could improve gum healing around dental implants, reducing inflammation and improving long-term implant success.
What could go wrong
This is a small, early-stage study with only 20 participants, so results may not apply to everyone. The intervention is a device, not a drug, so benefits may be modest.

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

Inclusion Criteria: * Inclusion Criteria of participants: * Periodontally and systemic healthy patients * Patients aged \> 18 years * Non- restored teeth for many reasons (i.e. endodontic failure, unworthy for treatment in deep caries/non-caries lesion and root fracture), locate in the posterior area in the maxillary or mandibular arch indicate for customized implant with no need for additional bone and soft tissue augmentation procedures. * An adequate vertical bone for immediate implant placement. * Implants will be positioned with adequate primary stability so that transmucosal healing can be accomplished. * No taken medications known to interfere healing or periodontal tissue health or bone metabolism. * No previous periodontal surgery at involved sites. * Good oral hygiene and good compliance with the plaque control instructions following initial therapy. Exclusion criteria: * Patients with active periodontal diseases (bleeding on probing- probing depth \> 4 mm) or those under orthodontic treatment. * Poor oral hygiene (full mouth plaque score \> 25% and full mouth bleeding score \> 25%) * Smoking habits (\> 10 cigarettes/day) * Severe acute or chronic periodontitis * Severe bruxism habits * History of oral/IV bisphosphonates taking * Remote or recent radiation therapy in the oro-maxillo-facial area or recent chemotherapy. * Xerostomia * Pregnant and lactating mothers * Patients who have been received periodontal surgery in the study area during the last year. * Clinical or radiographic signs of periapical pathology contraindicating immediate implant placement. * Implants showing signs of peri-implant mucositis and peri-implantitis during the study period will be excluded from the following analyses.
