Maintaining isolation on a labial access for #22 endo using the new Greataer Curve U-Band.
This case is borderline herodontics. However, I believe it has a good chance for long term success.
#22 is abscessed. Caries extends subgingival and apically a good distance down the root.
Introducing the new U-Band
A new addition to the Greater Curve line is the U-Band. It provides excellent isolation for Class V preps. (The U-Band will also traverse wide gap Class II"s and can easily fit over large diameter molars.)
Greater Curve U-Band in place
Attempted to place an assortment of rubber dam clamps. I was not able to get the clamp prongs beyond the apical extent of the prep margin. The U-Band fit past the apical margin and isolated very well. My intent was to build up the labial so I could place a clamp and rubber dam. However, the U-Band continued to isolate well and I had ample visibility for a labial approach to the root canal. For that reason I decided to not go with a rubber dam.
Master cone fit
I was able to irrigate with bleach and keep the tooth free of saliva throughout the shaping and subsequent root canal fill.
Root canal completed
There was a small gap along the mesial. I was able to seal the gap with a small silver piece of teflon tape.
Ready to shape
A2 Activa (Pulpdent) was bonded to complete the large Class V. Ready to shape once the matrix is removed.
Will be interesting to see how the gingiva responds since the attachment is gone. Will need to follow.
