Alveolar Ridge Sequelae Due to Peri-implantitis: a Retrospective Observational Study
Spain26 participantsStarted 2020-08-15
Plain-language summary
The scientific evidence available at present regarding the alterations suffered by the alveolar ridge after the explantation of implants that have been considered to be abandoned due to periimplantitis, as well as the remaining sequelae from said treatment, is scarce and inconclusive.
Regarding this background, it is speculated that the different types of peri-implant defects present different bone remodeling and different sequelae after the explantation of the implants affected by peri-implantitis.
Thus, it has been hypothesized that the peri-implant defect configuration has an influence on the radiographic bone alterations that occur after explantation.
In order to test this hypothesis, a retrospective study has been designed as it follows: Patients who have undergone implant placement procedure and suffer from peri-implantitis will be consecutively included in the study. In addition, patients should present at least 2 CBCTs taken before and after explantation, 4-6 months apart. Linear measurements will be taken in order to assess dimensional changes of the alveolar ridge at 1, 3, 5 and 7 mm from the bone crest.

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.
