This report describes a case of a root fracture on the upper left central incisor that was successfully treated using a conservative approach, by applying the restorative alveolar interface (RAI) management combined with tunnel technique and a subepithelial connective tissue graft (SCTG).<\/jats:p><\/jats:sec><jats:sec><jats:title>Case Presentation<\/jats:title><jats:p>A 24\u2010year\u2010old male patient presented with a provisional single\u2010unit fixed prosthesis on his upper left central incisor, in function for 4 years, with the chief complaint of prosthesis discoloration. After clinical and radiographic examination, a diagnosis of root fracture was established. Following the removal of the provisional prosthesis, a full\u2010thickness flap was elevated creating a tunnel. The elimination of the fracture line\/angle, root recontouring, and planning was then performed with the aid of a conical long diamond bur and periodontal curets. Additionally, an SCTG was placed buccally into the tunnel. The final zirconia layered with E\u2010max crown was placed 6 months after surgery. At 12\u2010 and 24\u2010month follow\u2010up, the periodontal tissues presented healthy aspect, no bleeding on probing, and a 4\u2010mm probing depth.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Surgical repositioning of the restorative margin can be an alternative and conservative treatment approach to compromised teeth with subgingival fracture line\/angle.
