industry report _ direct resin restorations I _Case study After careful clinical and X-ray examination of the tooth decay on the second upper left premo- lar (Figs. 1 & 2), we carried out a local anaesthesia with articaine 1:100,000. Before proceeding with the removal of the carious lesion, the adjacent tooth must be protected with a matrix and a wedge (Fig. 3). The access to the cavity is then provided and a rubber dam is placed. Once the operative field has been isolated, the decay is re- moved first by using a medium-grained diamond bur mounted on a red ring hand piece (Fig.4) and then a round (rosette) bur on a blue ring hand piece (Fig. 5). The preparation of the cavity is finishedwithafine-graineddiamondburonared ring hand piece (Fig. 6) and with a red rubber on a blue ring hand piece (Fig.7). In order to optimise the preparation of the cavity at the marginal level metal strips are first used (Fig. 8) followed by paper strips (Fig. 9). Once the preparation is finished the matrix V-Ring 4 is placed (Figs. 10 & 11) using the pin Fig. 5_Removing decay using a rosette bur on a blue ring hand piece.

Ideal for use in posterior areas with direct or indirect technique and especially to restore the function in a micro-invasive way respecting the neuromuscular system and getting an excellent aesthetic integration.
