the help of a burnisher. Thereafter, the wedge and the retainer should be removed carefully, keeping the band in position. The ends of the band (facial and lingual) should be held with the fingers of the two hands and everted in the opposite direction (for example while restoring the distal surface of a mandibular second molar, the ends of the band should be everted towards the mesial surface of the third molar (Fig. 13.16) and the band should then be gently moved occlusally in a shoeshine motion (Fig. 13.17)). The proximal surface at this point should be well-formed, with proper contact evident and minimal carving required (Fig. 13.18), except the possibility to remove a possible small amount of excess amalgam at the proximal facial and lingual margins (at the faciogingival and linguogingival areas) and along the gingival margin. The amal- gam knives are ideal for removing gingival excess, preventing gingival overhangs. They are also ideal for refining embrasure form around the proximal contacts. Checking Occlusion Before discharging the patient, occlusion has to be checked for high points (if any) present on the restoration. For this, articulating papers are used, which are usually blue/green/red in colour. The paper is placed on the arch where the restored tooth is present and the patient is asked to bite on it. If any high points are present on the resto- ration, they will appear more dark in colour (the colour of articulating paper leaves imprints), as compared with the areas on the adjacent teeth. These high points can then be selectively scraped off using a carver. The process is repeated up to the time no high points are seen any more. Finishing and Polishing Finishing and polishing of amalgam is one of the important steps to be performed to ensure the
