Single-Retainer Lithium Disilicate Resin-Bonded Bridge for Mandibular Central Incisor Replacement Using CAD/CAM and...

Rehabilitation of a missing mandibular central incisor with a resin-bonded single-retainer fixed dental prosthesis is challenging, particularly in young patients where implant placement may be contraindicated. This case describes the replacement of a mandibular left central incisor in an 18-year-old male following trauma, using a lithium disilicate single-retainer resin-bonded bridge fabricated via CAD/CAM technology and designed with a virtual articulator for occlusal optimization. A strictly enamel-limited preparation was performed on the left lateral incisor. The prosthesis was designed and milled from lithium disilicate glass ceramic (E.max CAD) and bonded following standard adhesive protocols. Immediate integration was achieved without occlusal adjustments. At 25 months, clinical examination revealed stable periodontal tissues, absence of inflammation, and satisfactory esthetic integration. This case highlights a conservative digital workflow for anterior mandibular tooth replacement, combining lithium disilicate material with virtual articulator planning to minimize adjustments and preserve dental tissues. Long-term studies are required to confirm durability in this indication.
