Figure 1: (a and b) Fractured maxillary incisor. (c) Buildup done on working model using cold cure acrylic resin. (d) Fabrication of thermoformed clear aligner on the build-up working model. (e) Etching on the margins of fracture margins (preparation of the margins may be required). (f) Application of primer followed by curing. (g) The retainer/template is seated to check for fit and to evaluate the approximate amount of composite that will be required. (h) Composite material (Tetric EvoCeram by ivoclar vivadent) of corresponding shade is filled in the tray with condensing instrument in the area to be restored; slightly excess material is advisable to create pressure compaction of the material. Excess material may flow on unwanted areas vaseline separation media should be applied on such areas. (i and j) Retainer is placed in position with mild pressure to be applied on the area to be restored to fit properly and compact the material. (k) Curing of the material is done from both labial as well as lingual aspect. Clear retainer facilitates easy curing. (l and m) Retainer is separated and removed from the arch carefully, the retainer sheets are lined with thin separating films; it avoids bonding of the composite with retainer. (n) Excaess material can be trimmed off using composite polishing kit. (o) If any voids observed in the margins of restoration it can be filled with flowable composite of same shade. (p-s) Final restoration after finishing and polishing and the retainer in place |
