Treatment of Horizontal Root Fractures in Traumatized Maxillary Central Incisors Using Minimally Invasive Surgical and Prosthodontic Foundation Techniques.

The aim of this study is to present cases of root preservations in which minor surgery and characteristic multifiber foundation were performed to treat maxillary central incisor root fractures near the bone margin. Two patients experienced root fractures of the central incisors due to short- or long-term trauma. Orthodontic extrusion was not employed in both cases; instead, minimal periodontal surgery was performed as pretreatment. In cases where the patient's tooth remained intact, fractured pieces were bonded. However, in cases where the root of the tooth was fractured with the prosthesis, a new restoration was fabricated. The roots were constructed using multiple characteristically placed glass fiber posts and materials with high biocompatibility and hydrophilicity as the foundation. Fractured teeth were esthetically restored using conservative or prosthetic treatment methods, resulting in patient satisfaction. No complications were observed at the 4-year follow-up. Although horizontal root fractures near the alveolar bone are generally considered to have a poor prognosis and esthetic outcome, they can be restored esthetically with minimal invasion by selecting appropriate procedures and materials.
