Use of temporary filling material for index fabrication in Class IV resin composite restoration
An 18 year old male with fractured maxillary left central incisor (Tooth 21) following a motorcycle accident came to the department of conservative dentistry, Kyung Hee university dental hospital. A clinical and radiographic examination revealed crown fracture on tooth 21 with pulp exposure and enamel fracture on maxillary right central incisor (Tooth 11) (). Tooth 21 was sensitive to percussion. Patient did not bring the fragment of Tooth 21 and he wanted quick and esthetic recovery. Root canal treatment and composite resin restoration using pre-restoration index technique was planned for Tooth 21, while simple resin restoration was planned for Tooth 11.\nOn his first visit day, root canal treatment was done under rubber dam isolation (). Shades of tooth were evaluated () using the VITAPAN classical shade guide (Vident, Brea, CA, USA) for resin selection. Fermit-N (Ivoclar vivadent, Schaan, Liechtenstein) was applied to the tooth defect. Approximate shape was made by gloved fingers () and then putty impression was taken ().\nThe putty index was partially cut between Tooth 11 and Tooth 21, and a celluloid strip was inserted to isolate Tooth 21 from Tooth 11 (). Palatal and interproximal enamel walls were modeled and opaque resin was layered (). Then, the access cavity was filled with resin (). The body of tooth was built up using composite resin with various shades () and the labial surface was covered with enamel resin (). Finally, finishing and polishing was performed ().\nAt one week follow up, scaling was performed and the fractured incisal enamel of Tooth 11 was restored.\nAt one month follow up, the restoration was well-maintained and gingiva was healed ().
