When a Gracey curette, no matter what the design, does not seem to access as well as you would like, another selection could be the Vision Curvette. Vision Curvettes provide excellent access to furcation areas and also help to improve access to deeper pockets in the anterior area. They provide very good adaption of the blade for narrow root surfaces and tight periodontal pockets (Figure 22). When comparing the Curvettes to a Gracey Curettes, the following design factors are noted:
Vision Curvettes have (Figures 23-25):
50% shorter blade
increased blade curvature
x to identify the cutting edge
longer shanks on posterior instruments (3mm)
Set of 4 Vision Curvettes: They are available in a modified Gracey set: Sub-0, 1/2, 11/12, and 13/14.
