OT-Bridge System Versus Multiunit Abutment for Mandibular All On-4 Screw Retained Prostheses.
Egypt20 participantsStarted 2023-12-13
Plain-language summary
This study aims to compare two different prosthetic systems used in mandibular full-arch implant-supported fixed prostheses (All-on-4). The study evaluates patient satisfaction and prosthetic complications associated with the OT-Bridge system versus multiunit abutments.
A total of 20 patients will be included and divided into two equal groups. All patients will receive implant-supported screw-retained fixed prostheses.
Clinical and prosthetic outcomes will be assessed at baseline (T0), 6 months (T6), and 12 months (T12), including evaluation of patient satisfaction and any prosthetic complications.
The findings of this study may help improve the selection of prosthetic systems to enhance clinical outcomes and patient quality of life.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adult patients (≥18 years) with edentulous mandible.
* Patients receiving or having received All-on-4 dental implants in the mandible.
* Adequate implant stability to support prosthetic loading.
* Patients indicated for screw-retained full-arch fixed prostheses using either OT-Bridge system or multiunit abutments.
* Patients willing to participate and attend follow-up visits at T0, T6, and T12 months.
Exclusion Criteria:
* Patients with uncontrolled systemic conditions affecting healing (e.g., uncontrolled diabetes).
* Patients with failed or mobile implants.
* Severe parafunctional habits (e.g., uncontrolled bruxism).
* Poor oral hygiene compliance.
* Patients unable to attend follow-up visits
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?
