Prospective Outcomes of Guided Equator Overdentures

Egypt40 participantsStarted 2025-09-01

Plain-language summary

This prospective clinical study evaluated the 3-year performance of mandibular implant-supported overdentures (IODs) placed using a fully guided static computer-assisted implant surgery (CAIS) protocol. Primary outcomes included implant survival, peri-implant soft tissue health, and marginal bone loss. Findings provide evidence for the predictability of digital surgical workflows in removable prosthodontics.

* Inclusion Criteria: * Completely edentulous mandible requiring implant-supported overdenture rehabilitation * Adequate bone volume to accommodate four implants in a quadrilateral configuration, confirmed by cone-beam computed tomography (CBCT) * Age between 40 and 75 years * Good general health with no systemic contraindications to implant surgery * Willingness and ability to provide informed consent * Commitment to attend all scheduled follow-up visits over the 3-year study period * Exclusion Criteria: * Uncontrolled systemic diseases (e.g., diabetes mellitus, osteoporosis) * History of radiotherapy in the head and neck region * Untreated oral infections or severe periodontal disease * Poor oral hygiene or inability to comply with maintenance protocols * Heavy smoking (\>10 cigarettes/day) or alcohol abuse * Known allergy or intolerance to materials or medications used in the study

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.
