Comparing Conventional Dental Implants and Trabecular Metal™ Dental Implants After Sinus Floor Elevation
United States33 participantsStarted 2012-07
Plain-language summary
This is a research study to test the clinical outcome of Trabecular Metal™ Dental Implants (TMDI) (Zimmer Dental Inc Carlsbad, CA, US) in the Maxillary Sinus region. This project will enroll 30 active subjects who will receive two dental implants in the edentulous maxillary molar region. This 24-month research study will examine the clinical stability of TMDI in both sinus elevation and sinus augmentation environments. The proposed research lays the foundation for improved health care by providing surgeons and restorative dentists with data for determining the effects TMDI have on clinical success in less than optimal osseous environments. The rationale that underlies the investigation is that identification of the influences of trabecular surface design on implant stability in varying bone types will allow routine, predictable use of early loading, which, in turn, will translate into more rapid, economical health care, and improved psychosocial well-being of the patient. If these hypotheses are correct, the results are expected to provide evidence based research data to support early loading and immediate loading of single implants in sites of adequate bone volume, and density with or without the use of graft materials in sinus lift procedures. In addition, it is expected that these results will fundamentally advance the field of implant dentistry and bioengineering by providing information on the principles of the bone density-mechanical environment-implant stability interaction.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* • The subject male or female between 21-75 years of age and has:
* The ability to understand and sign the informed consent prior to starting the study
* The ability and willingness to comply with all study requirements
* Adequate oral hygiene
* The presence of a atrophic, pneumatized, partially edentulous maxilla requiring a lateral approach technique
* Adequate bone volume to accommodate the planned endosseous dental implant (e.g. sufficient height of bone (5 mm or greater) such that the implant would achieve primary stability, and sufficient width that the implant could be placed within the confines of the existing bone without dehiscence or fenestration. The only implant length utilized in this protocol will be a 10 mm long TMDI (Zimmer)
* Existing teeth that are healthy and adequately restored, and desired a fixed restoration on implants
* had a negative pregnancy test within one week prior to surgery, if of childbearing potential.
Exclusion Criteria:
* Subjects who have smoked cigarettes or chewed tobacco within the past year
* History of alcoholism or drug abuse within the past 5 years
* Subjects with Severe bruxing or clenching habits
* Untreated periodontitis
* Subjects at undue risk for an outpatient surgical procedure
* Subjects with the presence of residual roots at the implant site
* Subjects with history of site development (extensive bone augmentation) at the implant site in the past 4 months
* Placement of implant in an e…
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?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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?
