Treatment of Post-Extraction Dehisced Socket - A Case Series Study
NCT02980211 · View on ClinicalTrials.gov ↗
Study Summary
PURPOSE The purpose of this case series is to clinically, radiographically and histologically evaluate the treatment of dehiscence defects in extraction sockets using a minimally-invasive GBR technique that involves the application of a particulate bone allograft and a non-resorbable PTFE membrane. METHODS Subjects with single-rooted teeth indicated for extraction and interested in future implant therapy for tooth replacement will be recruited on the basis of an eligibility criteria. A buccal or lingual dehiscence defect must strongly be suspected or confirmed upon clinical examination in order for the subject to qualify for study inclusion. A cone-beam computer tomography (CBCT) scan of the arch containing the tooth to be extracted will be obtained prior to tooth extraction. Following minimally invasive tooth extraction and debridement, the socket will be evaluated to verify the presence of a dehiscence defect affecting at least 50% of the bony plate height. After creating a soft tissue 'pouch' using tunneling instruments, a non-absorbable dense-PTFE (dPTFE) barrier membrane that will be trimmed to a size and shape that would allow for complete extension over the existing defect will be tucked between the mucosa and the alveolar bone. Then, the extraction socket will be grafted with particulate allograft and the access to the socket will be sealed with an extension of the membrane and an external cross mattress suture. Subjects will be recalled at 1, 2 and 5 weeks to monitor healing and assess the level of discomfort using a visual analog scale at the end of each visit. At the 5-week visit, the membrane will be gently removed and the exposed area will be left to heal by secondary intention. At 20 weeks after tooth extraction a second CBCT will be obtained to radiographically evaluate the site for implant placement. Bone volumetric reconstructions of the alveolar ridge at baseline and at 20 weeks will be made using the CBCT data to assess changes affecting the bone

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02980211
The ClinicalTrials.gov registry entry for NCT02980211 describes a study currently listed as completed. It is categorized as Phase 4, 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 17 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Gustavo Avila-Ortiz DDS, MS, PhD, which has 2 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 1 intervention — of which Alveolar Ridge Reconstruction is the first listed. 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: NCT02980211 reports 1 study location spanning 1 distinct geographic area — top geographies include Iowa. 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.
