Initial Stability of Posterior Maxillary Implants With Bicortical Fixation
NCT01237184 · View on ClinicalTrials.gov ↗
Study Summary
The primary purpose of this study is to 1. determine whether dental implant engaging both the alveolar crest cortical bone and sinus floor using vertical stopper drill and self-threading concept (bi-cortical fixation) increases initial implant stability compared to the short implants engaging only alveolar crest cortical bone (uni-cortical fixation) and/or ones engaging both crest and sinus floor but with green stick fracture (indirect sinus lift technique), 2. study whether different surgical techniques, residual bone height, bone density, and length and width of the implants used affect initial implant stability in posterior maxilla. In addition, this study will continue to 3. compare secondary implant stability of implants fixed bi-cortically, uni-cortically and with indirect sinus lift technique at 2nd stage surgery/6 month healing and 1 year follow-up from the restoration and 4. measure amount of endo-sinus bone formation from the 1- year follow up CT (computer tomogram) scan and evaluate safety and potential post-operative complications of bi-cortical fixation and indirect sinus lift technique reported throughout the follow up periods.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01237184
The ClinicalTrials.gov registry entry for NCT01237184 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 45 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Minnesota, which has 919 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Tooth Loss appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01237184 reports 1 study location spanning 1 distinct geographic area — top geographies include Minnesota. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
