Cylindrical, small, left, Prep of channel
The retrograde root canal treatment: limited space, restricted lateral access. Bone substance has to be protected and the stability of the tooth preserved. Rotating instruments sometimes produce the opposite effect: large bone windows, more difficult axial preparation of the canal.
The KaVo SONICflex retro system (0.571.0381) permits gentle and efficient sound-based retrograde root canal treatment with contra-angle diamond-coated tips:
Isthmus (left and right).
Cylinder (left and right).
T-shape (left and right).
Special tip for displaced apices.
Filling instruments (left and right).
