ABSTRACT
The indications for direct resin composite restorations are nowadays extended due to the development of modern resin materials with improved material properties. However, there are still some difficulties regarding handling of resin composite material, especially in large restorations. The reconstruction of a functional and individual occlusion is difficult to achieve with direct application techniques. The aim of the present publication was to introduce a new "stamp"-technique for placing large composite restorations. The procedure of this "stamp"-technique is presented by three typical indications: large single-tooth restoration, occlusal rehabilitation of a compromised occlusal surface due to erosions and direct fibre-reinforced fixed partial denture. A step-by-step description of the technique and clinical figures illustrates the method. Large single-tooth restorations can be built-up with individual, two- piece silicone stamps. Large occlusal abrasive and/or erosive defects can be restored by copying the wax-up from the dental technician using the "stamp"-technique. Even fiber-reinforced resin-bonded fixed partial dentures can be formed with this intraoral technique with more precision and within a shorter treatment time. The presented "stamp"-technique facilitates the placement of large restoration with composite and can be recommended for the clinical use.

With the visualization provided by the operating microscope (OM), it is now possible to place fillings in formerly inaccessible areas and work in a way that preserves the most enamel and/or dentin. The OM enables working with full overview in interdental areas or in hard-to-reach areas around crowns. The good view not only enables new forms of therapy, but reduces stress while working. The two clinical cases cited show clearly how the OM can be used advantageously in a range of situations--from the economical repair of a large old filling to minimal-invasive initial treatment. As an added bonus, the OP allows a completely relaxed and upright working posture.
