AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patients aged ≥18 years;
* Patients with partial edentulism;
* Patients with systemic health or controlled medical conditions;
* Patients with healthy or treated periodontal conditions;
* Patients enrolled in regular supportive periodontal therapy (SPT);
* Patients without clinical signs of oral parafunctions (bruxism or clenching);
* Presence of 1 osteointegrated dental implant in posterior region (premolar or molar) of mandible, after transmucosal placement and healing at 3-6 months;
* Tissue level solid-screw implants with a sand-blasted and acid etched (SLA) surface with an endosseous diameter of 4.1 mm, a length of 8, 10 or 12 mm, a shoulder diameter of 4.8 mm and a supracrestal machined neck with a height of 1.8 mm (Straumann Dental Implant System, Institute Straumann AG); Use of prefabricated titanium abutments;
* Monolithic zirconia SCs manufactured by digital flow; Screwed SCs with a mesial or distal cantilever extension;
* Alternative crown design (ACD) with eccentric implant insertion, with crown-like-premolar and with distal or mesial cantilever with ovoid conformation. In the latter case, the lower abutment cross-section in the region between the crown-bridge connector mimics the shape of a root, creating an "interradicular" access route to facilitate oral hygiene maneuvers;
* Absence of occlusal contacts or guidance on the cantilever extension at baseline;
* Opposing dentition consisting of natural teeth or fixed or removable 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?

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?
