The aim of this clinical report is to describe the successful treatment of a mandibular first molar presenting an extensive fracture at the buccal aspect in a young patient. The extension of the fracture was a negative prognostic factor for tooth maintenance. An alternative clinical treatment was proposed since the patient was young and presented with good oral hygiene and periodontal health. The treatment was based on orthodontic forced eruption associated with odontoplasty. A 3-year follow-up after the surgical procedure demonstrated the maintenance of periodontal health and good plaque control. It can be concluded that orthodontic forced eruption associated with odontoplasty promoted favorable conditions for prosthetic rehabilitation and is a feasible procedure in the treatment of tooth fracture extended below the cementoenamel junction.
