Figure 1.

(A) SEM, 20× magnification of a side view of an interactive bracket (In-Ovation-C*). A smooth, glasslike texture is observed with the new ceramic-injection-molded (CIM) processed slot. The closed clip is compressed producing a curved shape. This produces a passive-active clip that curves toward the depth of the 0.022″ × 0.028 archwire slot to actively seat wires that are ≥0.020″ round SS for controlled sliding. Chamfered slot end(s) to reduce couples (binding) during tipping. (B) Light stereomicroscopy of the facial view of the maxillary left canine In-Ovation-C bracket and clip in an open-slot position demonstrates glasslike slot smoothness. The anodized rhodium-coated clip provides an esthetic, pearlescent color blending esthetically with the CIM
