Effect of Bone-related and Soft-tissue-related Variables on the Marginal Bone Loss of Platform-matched and Platform Switched Dental Implants

Spain70 participantsStarted 2020-01-22

Plain-language summary

In this clinical trial the effect of the implant-abutment morphology (platform-switched vs platform matched) will be assessed in both soft tissue (soft tissue thickness) and hard tissue (marginal bone loss) outcomes. Several clinical predictors (initial implant position level, gingival biotype, abutment height and prosthetic emergence profile) will also be taken into account as modulating factors of the clinical outcome.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients of legal age (\>18 years). * With rehabilitation needs with 1 maxillary or mandibular implant in mature bone (more than 4 months after tooth extraction) in the posterior sector (premolars and molars). * With good hygiene (plaque and gingival index ≤ 25%). Exclusion Criteria: * Medical conditions that contraindicated implant surgery. * Patients with immunological alterations, pregnant and lactating. * Heavy smokers \> 20 cigarettes/day, * Requiring bone augmentations or of soft tissues. * Patients whose anatomy prevented the correct three-dimensional placement of the implant to perform prosthetically guided screw-retained restorations.

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.
