A Study Comparing Two Different Denture Base Materials in Implant Retained Overdentures
Egypt16 participantsStarted 2024-07-15
Plain-language summary
The aim of removable prosthodontics is not only to restore lost oral structures but also to preserve the remaining tissues. Implant-retained overdentures have shown superior outcomes over conventional dentures by reducing residual ridge resorption, enhancing prosthesis support and retention, and improving patients' quality of life. Retention can be further optimized through the use of various attachment systems such as bars, studs, magnets, and telescopic crowns.
Traditional PMMA denture bases have limited flexibility, making their extension into soft-tissue undercuts challenging. The introduction of flexible resin materials has improved adaptation to deeper undercuts, enhancing retention while minimizing patient discomfort and absorbing functional stresses. Additionally, flexible resins may reduce microbial colonization by improving blood circulation to the underlying mucosa and supporting salivary defense mechanisms against Candida albicans.
Recently, innovative attachment systems such as Novaloc have been developed, featuring PEEK retentive caps and an amorphous diamond-like carbon coating to minimize wear and maintain long-term retention. Their versatile design allows better accommodation of gingival variations and contributes to improved patient satisfaction and treatment success.

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?
