The Prepless Approach for Cantilever Resin-Bonded Bridge Using Computer-Aided Design and Manufacturing Technology for the Minimally Invasive Replacement of a Maxillary Central Incisor: A Case Report of a Rare Procedure

Replacing a maxillary central incisor in young patients presents both aesthetic and functional challenges, particularly when implant therapy is contraindicated due to ongoing post-pubertal craniofacial growth. This case report describes the use of a prepless cantilever resin-bonded fixed dental prosthesis fabricated from lithium disilicate using a Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) workflow to restore a maxillary central incisor in a 20-year-old female patient. The treatment involved selective removal of aprismatic enamel without conventional tooth preparation, promoting dental tissue preservation and adhesion. A silicone repositioning index ensured accurate clinical placement of the bridge. At 20 months, the restoration demonstrated excellent aesthetic, biological, and functional integration. This technique represents a reliable, conservative, and aesthetic alternative to implants in carefully selected young patients.
