<br/><br/> Introduction: While the anterior cantilevered resin-bonded fixed dental prosthesis (RBFDP) is now well established among orthodontists and general practitioners, the posterior cantilevered RBFDP has only more recently gained attention in the international literature. The aim of this article is to provide an overview of this therapeutic option and its rationale, based on an original chairside clinical case performed in a single session. Materials and Method: A clinical case involving a 20-year-old female patient is presented. The patient exhibited a missing mandibular molar due to extraction following a vertical root fracture. A posterior cantilevered RBFDP was proposed and accepted. The restoration was designed as a monolithic stained and glazed 4Y-TZP zirconia with partial occlusal veneer preparation on abutment tooth. Tooth preparation was limited to the enamel. The intaglio surface of the prosthesis was sandblasted with 50 µm aluminum oxide and treated with a universal primer. The prosthesis was bonded under rubber dam isolation using preheated resin composite, following a strict light-curing protocol and a “no-finishing” approach. Clinical adjustments were made and postoperative occlusion was verified. Results: The single-visit restoration demonstrated good aesthetic and functional integration at follow-up. The key steps in fabricating a posterior cantilevered RBFDP are illustrated and discussed. Discussion: Through the simple, systematic, and reproducible approach proposed in this article, the posterior cantilever RBFDP emerges as a reliable therapeutic option. Although the chairside approach is less commonly used, it can enhance treatment efficiency and patient comfort. Conclusion: This innovative treatment strategy is of particular interest to orthodontists and general practitioners, especially for patients in whom implant therapy is contraindicated or undesirable, such as younger individuals. It also holds value for the general population once the implant alternative has been discussed.
