Abstract
Background: Resin-bonded fixed dental prostheses (RBFDPs) represent a minimally invasive solution for replacing missing anterior teeth. The evolution of ceramic materials, particularly lithium disilicate, combined with digital CAD-CAM workflows has significantly enhanced the clinical predictability and aesthetic outcomes of these restorations.
Case Presentation: A 33-year-old male patient presented with a missing maxillary left lateral incisor (#12) and multiple missing mandibular anterior teeth following trauma. A lithium disilicate RBFDP was planned and fabricated using intraoral scanning and CAD-CAM technology for the maxillary arch. Abutment preparation was conservative, with supragingival shoulder finish lines created on teeth #11 and #13. The prosthesis was cemented with self-adhesive resin cement following acid etching protocols.
Conclusion: This case demonstrates that lithium disilicate RBFDPs fabricated through a digital workflow provide a reliable, aesthetic, and minimally invasive alternative to conventional fixed partial dentures and implant-supported prostheses for selected patients. Meticulous case selection, surface preparation, and adhesive protocol adherence are pivotal to long-term success.
