88-year-old white female, previously restored with an 8-unit bridge, numbers 5-12, after a traumatic accident in 2012. now living in an assisted living facility, fell and fractured pontics 8 and 9 out of porcelain-fused-to-zirconia bridge.
consulting with the family, in an effort not to have to replace the entire bridge, required creative thinking. prior to an alginate impression of the fractured bridge, linguals of 6, 7, and 10 were prepared for resin-bonded bridge.
a pi-ku-plast resin pattern was fabricated using the broken out pontics and seating rests on 7 and 10.
resin pattern was invested and pressed in lithium disilicate; then pontics were fitted into the lithium disilicate frame.
the pontics were cemented into the lithium disilicate frame with rely-x ultimate dual cure cement in the lab in a totally dry environment after the pontics and the frame were sandblasted, primed and bonded.
frame and pontics were cemented to the existing bridge with the rely-x ultimate and cured in the mouth. then the seating rests were removed with a diamond burr.
this was an economical solution to a very difficult situation for the patient and the family, and by using the existing pontics and converting to a resin-bonded bridge, all parties were happy and grateful.
