Abstract

Background: Molar-Incisor Hypomineralization (MIH) is a developmental enamel defect affecting first permanent molars and often incisors, presenting unique restorative challenges. In line with minimally invasive dentistry, the “Würzburg concept” promotes conservative management strategies with resin infiltration.

Objectives: This case report investigates the impact of modifications to the ICON resin infiltration protocol on esthetic outcomes and adhesion in MIH-affected anterior teeth.

Method: Three clinical cases involving MIH lesions on anterior teeth were treated using the Icon® resin infiltration system by DMG (Hamburg, Germany).

Results: Preconditioning hypomineralized enamel with 5.25% sodium hypochlorite followed by resin infiltration enhances the physical integrity of composite resin restoration. Enhanced esthetic results were observed, especially when multiple Icon-Etch cycles and extended infiltration times were applied to white or creamy opacities.

Conclusion: A modified ICON resin infiltration protocol achieves esthetic results that align with patient expectations and satisfy clinical standards.
