Atraumatic Restoration of Vertical Food Impaction with an Open Contact Using Flowable Composite Resin Aided by Cerclage Wire under Tension

Figure 3

Acid-etching of the contact area under tension stress with the cerclage wire. (a) Applying 20% or 37.5% H₃PO₄ gel around the contact area. ((b), (c)) The tension band was enforced with the cerclage wire by squeezing the acid agent into the contact area for 20 s. (d) Rinsing the acid agent thoroughly with water.
