Objective This clinical report describes an alternative treatment modality for the replacement of congenitally missing maxillary lateral incisors in a 17‐year‐old patient. Clinical Considerations Zirconia‐based resin‐bonded fixed partial dentures ( RBFPDs ) were selected as a viable and conservative treatment option in a young individual with highly aesthetic expectations. Fabrication of all‐ceramic RBFPDs followed specific preparation design and features to accommodate two retainers. The zirconia frameworks with bilateral wings were digitally designed and then milled by a computer‐aided design and computer‐aided manufacturing ( CAD / CAM )‐controlled milling machine. Zirconia surface was treated with a two‐step chairside tribochemical silica‐coating/silane coupling surface treatment protocol, and adhesive resin luting cement was used to achieve micromechanical and chemical bonding. Completion of the treatment resulted in a functional and aesthetic successful outcome and a 17‐month follow‐up presented uneventful. Conclusion Contemporary adhesive techniques involving resin‐bonded zirconia‐based prostheses can be utilized successfully and predictably in young patients with single missing teeth when implant therapy is currently not a treatment of choice and a less invasive approach is desired. Clinical Significance The zirconia‐based resin‐bonded prosthesis constitutes a viable and conservative treatment modality for the replacement of missing teeth either congenitally or from another etiology in young patients in which implant therapy and a fixed partial denture are currently contraindicated.
