Deep carious lesions are very common in everyday clinical work. In modern dentistry, the goal is to ensure the permanence of direct or indirect restoration in extensively lost dental tissues, with the emphasis on the aesthetics of the restoration. Removal of the deep carious lesions results in subgingival preparation located below the enamel-cement joint. Such a defect is difficult to make up for because of the reduced visibility as well as the maintenance of a dry working field and thus complicating the making of the appropriate direct filling. Moreover, in the case of indirect replacements, it affects imprinting of the preparation and its cementation. Surgical lengthening of the clinical crown of the tooth may be one of the solutions when the level of the gingiva is surgically lowered to allow access to the border of the preparation. Such an approach also has its drawbacks such as disruption of biological width, loss of attachment, dentinal hypersensitivity, and possible exposure of root furcation. A minimally invasive restorative procedure that would ensure the raising of the preparation edge in one visit with the use of composite resins is called deep margin elevation. The technique was first described in 1998 by Dietschi and Spreafico. With the help of specially designed matrices, a dry working field is ensured and with the use of the composite increments the preparation limit is elevated by 2 milimeters supragingivally. In addition to the primary advantage of preserving teeth that are often doomed to extraction, the technique has several additional advantages such as reduced number of complications, the ability to make a dental impression in the same visit and minimal invasiveness. In the case of indirect restoration, after making a marginal ridge with the use of composite, a bite-wing image is made to assess the marginal closure. If the result is judged to be satisfactory, it is followed by making an impression, indirect restoration and cementation.
