Can a new incision method prevent wound opening after bone grafts?
NCT ID NCT07753525
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This trial tests a new surgical approach called the Tooth Collar Technique (TCT) for jawbone augmentation, a procedure that adds bone to the jaw before dental implant placement. The technique aims to allow the gum tissue to close more easily and reduce the risk of the wound reopening after surgery. Researchers will compare healing outcomes in 30 adults who need bone augmentation, using standard biomaterials and membranes. The study focuses on whether TCT improves early wound healing and reduces complications like wound dehiscence.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Tooth Collar Technique (a modified surgical incision method for bone augmentation)
- What this could lead to
- If successful, this technique could reduce complications and improve healing for people needing jawbone grafts before dental implants.
- What could go wrong
- This is a small early-stage study, so results may not apply broadly. As with any surgery, there are risks of infection, bleeding, or poor healing.

Inclusion Criteria: * Voluntary written informed consent of the participant or their legal authorized representative has been obtained prior to any screening procedures * At least 18 years of age at the time of signing the Informed Consent Form (ICF) * Indication for horizontal and/or vertical bone augmentation in the maxilla or mandible in preparation for implant placement * Sufficient general health to undergo elective oral surgical procedures, as judgjed by the investigator * Ability and willingness to attend all study visits and comply with the protocol requirements. Exclusion Criteria: * Current smoking or use of other nicotine-containing products (eg, e-cigarettes, chewing tobacco) * Presence of uncontrolled systemic diseases that may compromise healing * Ongoing chemotherapy, radiotherapy, or bisposphonate/anti-resorptive therapy in the head or neck region * History of radiation therapy to the jaws * active or untreated periodontal disease, caries or poor oral hygiene * Poorly fitting restorations on teeth adjacent to the augmentation site * Known allergy or hypersensitivity to any material used in the augmentation procedure. * Pregnant or breastfeeding women, or women planning pregnancy during the study period. * Participation in another interventional clinical study within the last 30 days * Any other condition or circumstance that, in the opinion of the investigator, could compromise participant safety, compliance, or the validity of the study results. * Participation in an interventional study with an investigational medicinal product or device.
