While plastic wedges along with the Teflon-floss approach could most likely offer improved cervical adaptation compared with wooden wedges, their ability to different enamel is at this time uncertain. While stiff matrices may have an element of coronal self-stabilisation, it truly is prudent to additional stabilise the matrix with unbonded flowable composite (Fig. twelve). This passive coronal stabilisation, allied with the minimised probable for extrusion distortion, very likely raises the chances of getting an undistorted matrix.
The enamel increment was positioned into your facial part of the planning, such as the facial portion of the marginal ridge. The cuspal projections have been sculpted, as well as depressions amongst were made in order that a few of the stain during the previous layer would exhibit by means of (Determine fifteen).
