Objective: This clinical case presents the protocol and follow-up outcomes of a posterior resin-bonded fixed partial denture (RBFPD) with a single-retainer design made of lithium disilicate for the replacement of a congenitally missing premolar in a young adult.
Methods: An 18-year-old woman presented an esthetic complaint due to a congenitally missing premolar. Bone and soft-tissue deficiencies were present, and the patient was reluctant to perform any surgical procedure to replace the missing tooth. A minimal invasive preparation was performed in a single adjacent tooth strictly within the enamel. A lithium disilicate (IPS E.max, Ivoclar, Vivadent) single wing RBFPD was produced and luted with resin cement (G-cem link force, GC).
Results: A follow up of 24 months showed success and survival without debonding or signs of fractures to the restoration.
Conclusion: Single retainer posterior RBFPD made from Lithium disilicate exhibits promising durability and retention. This design should be considered as a minimal invasive alternative for a dental implant in the posterior dentition in young adult, and as a conservative treatment involving only a single adjacent tooth compared to double retainer RBFDPs.
