The «One-piece» tuberosity graft applied to the «Immediate Dentoalveolar Reconstruction» technique in immediate implant placement in the esthetic zone: a novel user-friendly modification

Description :

Descriptive Summary: This prospective clinical study aims to evaluate hard and soft tissue outcomes following immediate implant placement with buccal plate reconstruction using an autogenous tuberosity muco-cortico-cancellous graft. Adult patients requiring single-tooth extraction in the anterior maxillary region, with buccal plate dehiscence ≤ 1/3 of bone height, will be enrolled. A minimally traumatic, flapless extraction technique will be used. Implants will be placed in a prosthetically driven position, and the buccal defect reconstructed with the harvested autogenous graft. Wound closure will be achieved using resorbable sutures left in situ to undergo spontaneous resorption. Clinical and digital data will be collected at four time points: preoperative (T0), immediate postoperative (T1), 4 months (T2), and 12 months (T3). CBCT scans will assess buccal bone thickness at 0, 2, and 4 mm apical to the implant neck, while intraoral scans will evaluate soft tissue contour changes. Postoperative complications, including infection, graft exposure, soft tissue dehiscence, and implant failure, will also be recorded. The study combines digital imaging (CBCT and STL superimposition) with standardized clinical procedures to provide a precise evaluation of bone and soft tissue stability over 12 months, aiming to optimize immediate implant protocols in the aesthetic zone while minimizing patient morbidity.
