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 Results may not be published yet.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.

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

Researchers at Cairo University are testing two methods for placing dental implants right after removing a molar. In one method, they drill through the bone between the roots before pulling the tooth, then place the implant. In the other, they remove the tooth first and place the implant into the fresh socket. The trial measures implant stability, how accurately the implant is positioned, how long surgery takes, and how much pain patients feel afterward.

What this could mean

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

Active substance
Two surgical techniques for placing dental implants after molar removal: drilling through the roots before extraction, or placing the implant into the fresh extraction socket
What this could lead to
If one technique proves more stable and accurate, it could guide dentists toward a more predictable way to replace molars right after removal, possibly reducing the need for a second surgery.
What could go wrong
This is a small study of 20 people at a single dental school, so results may not apply to all patients or clinics. Implant surgery carries usual risks such as infection, pain, or implant failure, and the technique may not work for every molar shape.

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 years or older. * Both sexes. * Cooperative patients likely to maintain good dental health. * Adequate bone height for placement of implants with a minimum implant length of 7 mm. Exclusion Criteria: * \* Patients who had undergone previous extraction of all remaining teeth. * Implant placement in both healed bone and extraction sites during the same procedure. * Presence of any local or systemic factors contraindicating oral surgery. * Poor oral hygiene. * Conditions that may complicate wound healing, including uncontrolled diabetes, smoking of 10 cigarettes per day, pregnancy, history of drug or alcohol abuse, and inability or unwillingness to return for follow-up.
