CATEGORY 54 AUSTRALASIAN DENTIST CLINICAL smooth restorative margin. FL-Bond II Primer was applied on slightly exposed dentin surface and left undisturbed for 10 seconds followed by FL-Bond II bonding agent (Shofu Inc. Japan) applied in an even layer over entire etched tooth surface (Fig. 11) and photocured for 20 seconds. Creating the Palatal Shell A small amount of Beautifil Injectable XSL shade A2 (Shofu Inc. Japan) a bioactive restorative material was injected in a small amount and placed on the palatal putty index in the area of the tooth to be restored (Fig. 12) and the putty index was then placed on the palatal aspect of anterior teeth. The restorative material was spread & teased with a thin probe onto the palatal aspect of the preparation and photocured for 20 seconds (Fig. 13). The self-levelling flow properties of this novel restorative material permits gentle spread and preparation of a thin even palatal base layer. The putty index is removed and the prepared palatal shell is examined (Fig. 14). Photocuring is done for 20 seconds from the palatal aspect. Excess material was gently trimmed using No.12 surgical blade. This palatal shell will serve as a base for further placement of restorative material. Inject and Shape with Bioactive Injectable Composite A layer of Beautifil Injectable X was then placed on the palatal shell layer & gently spread using a probe & No. 5 Unibrush (Shofu Inc. Japan). The unique properties of this restorative does not allow the material to flow freely and the material holds its shape. The material was injected and shaped to be slightly thick on the apical aspect of the defect and gently spread over the fracture line, while forming a thinner layer towards incisal aspect (Fig. 15 & 16). The injectable composite layer was then photocured for 20 seconds. Translucency effect was created by adding Lite Art blue stain (Shofu Inc. Japan) on the incisal aspect & gently spread using no. 5 Unibrush before photocuring for 20 seconds (Fig. 17 & 18). Two more layers of Beautifil Injectable X A2 were added subsequently to get the desired fill & anatomy of the fractured segment (Fig. 19-20). Each layer was photocured for 20 seconds and a final curing of 40 seconds for each surface was carried out after application of glycerine to minimize the oxygen inhibited layer on the surface. (Fig. 21) Finishing and Polishing Protocol Gross finishing was completed under rubber dam using Super-Snap medium disk (purple) & TR21F (Mani Inc. Japan) fine grit bur on slow speed hand-piece (Fig. 22-23). OneGloss Midi point (Shofu Inc. Japan) was then used to smoothen the surface and create secondary surface anatomy (Fig. 24).
