AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* • Patients were healthy and free from all systemic diseases that affect osseointegration or bone resorption around the implant as recorded from medical and dental history.
* Patients were free from all oral pathological conditions and any remaining roots which were verified by pre-operative panoramic radiograph.
* Patients with U shaped arch, flat mandibular alveolar ridge covered with even compressibility healthy mucosa and gingival thickness of about 2mm verified by dual scan of cone beam computed tomography (CBCT) during treatment planning. Fig.(1)
* Adequate residual alveolar bone quality D2 bone type in the anterior and premolar regions according to the Misch bone density classification scheme (850 to1250 housefield units) confirmed by CBCT.
* Angel's class I maxillomandibular relation with moderate inter- arch space (20 mm) confirmed through tentative jaw relationship, and restorative space of at least 15 mm determined by putty index technique
* Patients complain from poor retentive mandibular denture seeking for alternative fixed options.
* Patient who is motivated, agreed with the follow-up visits and willing to return for follow-up appointments.
Exclusion Criteria:
* • Patient with absolute contraindications that interfere with surgical placement and osseointegration of implants as uncontrolled diabetes mellitus, generalized osteoporosis, recent myocardial infarction, patient with radiotherapy.
* Patient with relative contrain…
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?
