Abstract This case highlights the use of lithium disilicate as posterior prosthesis instead of traditional anterior prosthesis through proper case selection and optimized bonding protocol. A 35-year-old female presented with the chief complaint of a missing upper right first molar, extracted one year earlier due to caries. Based on Clinical and radiographic evaluation, the condition was diagnosed as a single posterior edentulous space suitable for conservative adhesive rehabilitation. All possible treatment options were discussed but the patient opted for a minimally invasive approach. So, lithium disilicate resin-bonded bridge was fabricated with minimal preparation and bonding protocol included hydrofluoric acid etching, silane application, and cemented with dual-cure resin cement. At the 6-month follow-up visits, the restoration exhibited satisfactory occlusion, function, and esthetics, with no evidence of debonding or complications. This case underscores that resin-bonded all-ceramic prostheses can be extended to posterior tooth replacement when supported by careful planning and adhesive protocol.
