Dimensional Changes in Single Crowns Supported by Short Transmucosal Implants With Diverging or Converging Neck Profiles in the Esthetic Zone
Peru20 participantsStarted 2023-04-01
Plain-language summary
The goal of the present randomized clinical trial is to assess the long-term osseous and peri-implant soft tissue changes as well as the success rate of short implants (6 mm) with a converging collar with micro threads or a diverging polished collar placed in the esthetic zone of the maxilla on partially edentulous patients. The main questions it aims to answer are:
* what are the long-term bone and soft tissue changes around implants with a converging collar with micro threads compared to a diverging polished collar placed in the esthetic zone of the maxilla?
* What is the success rate of implants with a converging collar with micro threads compared to a diverging polished collar placed in the esthetic zone of the maxilla? Dental implants with a converging collar with micro threads or a diverging polished collar will be placed in the esthetic zone of the maxilla of the included participants and the measurements regarding the bone and soft tissue level will be compared.

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?

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?
