Evaluation of Marginal Bone Loss and Associated Factors Around Ziacom Dental Implants With Different Prosthetic Connection
Spain42 participantsStarted 2023-07-10
Plain-language summary
Dental implants may suffer from bone loss around them, particularly at the upper portion where the prosthesis starts. The connection between both parts of the tooth restoration is key for avoiding micromovement during chewing, bacterial contamination and initiation of bone loss. Thus, investigating factors related to this bone loss in different types of implant-prosthetic connections is key for promoting better use of available therapeutics devices. In this study, we will study marginal bone levels over time as well as bacterial contamination and inflammatory markers in the peri-implant sulcus around implants with connical connection and compare them with those obtained when using implants with internal hexagonal connection. The hypothesis is that bone loss will be higher in implants with hexagonal connection associated with a pathological microbiome in the sulcus that induces a higher inflammatory response.

Inclusion Criteria:
* One missing tooth in the premolar or molar area with both opposing and adjacent teeth (mesial and distal).
Exclusion Criteria:
* One-stage bone augmentation.
* Uncontrolled type 1 or 2 diabetes (HgA1c\>8).
* Known auto-immune or inflammatory disease.
* Severe hematologic disorders, such as hemophilia or leukemia.
* Local or systemic infection that may compromise normal healing (e.g., extensive periapical pathology).
* Liver or kidney dysfunction/failure.
* Currently receiving cancer treatment or within 18 months from completion of radio- or chemotherapy.
* Long-term history of oral bisphosphonates use (i.e., 10 years or more).
* History of intravenous bisphosphonates.
* Long-term (\>3 months) history of antibiotics or drugs known to alter the inflammation and/or immunological system 3 months before inclusion.

* Pregnant women or nursing mothers.
* Not able or not willing to follow instructions related to the study procedures.
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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
