The Tooth Collar Technique

The aim of this study is to evaluate wound healing after the application of the Tooth Collar Technique (TCT) for bone augmentation in the upper or lower jaw. This technique is designed to promote tension-free wound closure and to reduce the risk of wound dehiscence. Augmentation is performed under local anesthesia. The gingiva is opened according to the TCT, after which the bone defect is reconstructed with standard biomaterials and covered with a membrane. No experimental materials are used- only a modified incision technique.

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.
