Comparing 7 mm and 5 mm Implants Placed Immediately After Molar Extraction
Albania70 participantsStarted 2021-10-01
Plain-language summary
This clinical study aims to evaluate the performance and long-term outcomes of immediate dental implants placed in molar sites after tooth extraction. Eligible patients will receive one implant and a single crown in a posterior area (first or second molar). The study will compare implant and crown success over a five-year period, tracking complications, bone changes, aesthetics, and patient satisfaction. Participants must be at least 18 years old and have sufficient bone to allow immediate implant placement. This research will provide important data on the safety and reliability of immediate implants in posterior areas.

* irradiation in the head or neck area
* uncontrolled diabetes
* pregnancy or lactation
* untreated periodontitis
* poor oral hygiene and motivation
* addiction to alcohol or drugs
* psychiatric disorders
* unrealistic expectations

* participation in other studies interfering with present protocol.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Number of failed crowns (not placed or remade due to implant/prosthetic failure)
Timeframe: From implant placement to 5 years after loading.
2
Number of failed implants (implant mobility, infection, or mechanical complications)
Timeframe: From implant placement to 5 years post loading.
3
Biological and biomechanical complications
Timeframe: From implant placement to 5 years after loading.
