Teeth with molar incisor hypomineralization (MIH) present with substantial dental tissue loss, requiring restorations with materials able to provide satisfactory clinical performance. This paper presents a clinical report of an 11 years of age patient diagnosed with MIH. Repeated previous treatment with composite resin and glass ionomer was reported. A low-shrinkage composite resin was used as a core build-up material. The tooth was prepared for a complete crown. A preformed-malleable composite-resin-based material (Protemp™ Crown Temporization Material; 3MESPE, St. Paul, MN, USA) was used to fabricate the restoration that was cemented definitively with a self-adhesive resin cement (RelyX^® Unicem 2, 3MESPE, Seefeld, Germany). The patient was followed for up-to 18 months with excellent gingival health. There was no noticeable wear or significant discoloration of the restoration. Preformed-malleable composite-resin-based material may be a viable treatment approach to restoring teeth with MIH.
