Use of temporary filling material for index fabrication in Class IV resin composite restoration
A thirty-year old male visited the clinic due to fracture of maxillary left central incisor (Tooth 21) by car accident. Though he went to emergency room of another hospital just after accident, he did not get any particular dental treatment. During the clinical and radiographic examination, there was no pulpal exposure on Tooth 21, but patient complained of discomfort upon ice and hot tests. He was diagnosed as crown fracture with reversible pulpitis on Tooth 21 and enamel fracture on maxillary right central incisor (Tooth 11) ().\nPatient hoped for rapid and esthetic single-visit treatment. Composite resin restoration using pre-restoration index technique was planned for Tooth 21, and simple composite resin restoration was planned for Tooth 11. It was explained to the patient that root canal treatment may be necessary on Tooth 21 depending on the patient's symptom during follow-up.\nIn this case, Fermit (Ivoclar vivadent) was used to form appropriate shape and putty impression was taken (). After index and celluloid strips were placed, palatal and interproximal enamel walls were modeled and opaque resin was layered (). The body of tooth was built up using various shades of composite resins () and enamel resin was applied as the labial surface (). Finally finishing and polishing was performed ().\nAt next visit in clinic, the patient complained of pain at rest on Tooth 21. Root canal treatment on Tooth 21 was performed and then Tooth 21 was restored with fiber post and composite core (). At three weeks after restoration, fractured incisal enamel of Tooth 11 was restored and shade of Tooth 21 was modified.
