Figures 1–9. Figure 1. Cross section of access canal showing the (a) silicone plug (or cotton pellet), (b) panacea, and (c) the composite/resin. Figure 2. Screw access opening. Figure 3. Place a layer of panacea resin over the silicone obturator or cotton pellet. One of panacea's properties is setting expansion. This helps reduce microleakage, which may cause odor release during future screw removal. Figure 4. The nonesthetic darkness comes from the area of the screw and lateral walls of the screw access opening. Use the large amalgam burnisher to provide optimal results when using the opaque (dentin) composites. Figure 5. Take opaque (dentin) composite and fill the remaining area of the access opening. Compress the burnisher into the access opening. Figure 6. The burnisher will create a cone-shaped impression on top of the resin, masking both the screw area and the lateral walls. Figure 7. This technique allows the dentin composite to be thick on the walls of the screw access opening. The resin is then light cured, and the cone-shaped impression will conveniently mark the entrance of the access opening. Figure 8. Enamel composite can be used to fill the coned area for optimal esthetics. Figure 9. Clinical photos showing the screw access opening (a), cotton pellet (b), placement of panacea (c), and placement of resin (d)
