[New method for preparation of fiber reinforced temporary crowns and bridges]

In many situations there is an indication for the creation of a long term, functional, chairside temporary bridge or crown. Utilizing a cold-light dual-cure composite material, Dual cement, reinforced with Polyethylene fibers, an excellent, strong bridge or crown will result. The technique is as follows: replace missing tooth/teeth by hand shaping Helioprogress composite restorative to a pontic-form. It will stay in place firmly enough while the Bluephase "mold" impression is taken. Then prepare teeth as they will be needed (no undercuts). By closing their mouth patients coat their teeth with saliva which will act as a separator. Now three fiber bundles in proper length will be used to reinforce the dual cured composite. Wet the fibers with Heliobond to saturate the bundles and wet each filament in the bundles. Examine the internal portions of the Eos Bluephase impression and alter by cutting if necessary to create an acceptable negative tooth shape. Cut a relief hole in the deepest corner of each of the teeth to be duplicated, with a No 4 round bur which will allow the trapped air to escape as the filled mold is repositioned over the teeth to form the temporary restoration. The carefully mixed Dual cement is now pressed in a small amount into each of the preparations involved.(ABSTRACT TRUNCATED AT 250 WORDS)
