Hypomineralized molar rehabilitation with CAD/CAM technology in an adolescent

Abstract

Introduction: Molar-incisor hypomineralization is a qualitative enamel defect affecting permanent first molars and possibly incisors. It manifests as opaque areas, discolorations, and a high susceptibility to fractures, sensitivity, and caries. Its treatment depends on the pulp diagnosis and the extent of the damage. In severe cases, adhesive indirect restorations are a conservative and functional option. Case report: A 10-year-old patient presented for rehabilitation of tooth 1.6 after endodontic treatment. The patient was diagnosed with hypomineralization with significant structural loss. An adhesive restoration using CAD/CAM ceromer inlay was planned. After rubber dam isolation, sealing was performed using glass ionomer and Bulk Fill resin, followed by margin elevation, digital scanning, and design with CEREC software. The clinical fit was successful. Cementation followed the 3M universal adhesive protocol using RelyX Ultimate Clicker. The patient was monitored with no signs of discomfort or functional failure. Conclusion: The use of CAD/CAM indirect restorations in severely hypomineralized teeth after endodontics enables conservative, aesthetic, and functional rehabilitation. This modern approach, combined with rigorous clinical protocols, provides excellent outcomes in pediatric patients.
