Bonding Danville's Snowpost

Step 6.   Clearfil Photo Core (Kuraray America) is the preferred core material of the authors. Other auto cure, dual cure, or self cure core materials are compatible since the 2B (or Panavia F) is dual curing. The excess 2B (or Panavia F) is not removed from the canal entrance but instead the core composite is placed directly against the 2B (or Panavia F). If Photo Core is used, light cure it immediately after placing (figure 5). The Photo Core has an exceptionally deep light cure ability so it may normally be placed in only one increment.

Helpful Hints

Step 7.   After curing, the core is trimmed with a rotary diamond (figure 6) and impressions taken. If the Snowpost protrudes from the core, it is easily trimmed with the rotary diamond. Caution should be used to prevent inhalation of any fibers produced by trimming. Rubber dam isolation is ideal. The Photo Core is dentin shaded and difficult to see if cut wet. When cut dry, it becomes opaquish white and is easily differentiated from dentin.

Step 8.   The resulting post, core and crown are is esthetic (figure 7) and all components are fully bonded and sealed. This type of core is believed to be the state of the art for esthetic and durable restorations of endodontically treated teeth (figure 8). The Snowpost is easily observed on X-ray.
