Carefully finished cavity margins have a considerable influence on the life-span and aesthetic appearance of tooth-coloured restorations. With the help of the diamond-coated hand instruments the margins are evenly levelled. Irregularities such as loosened enamel rods are removed.
Benefits : The use of hand instruments ensures full tactile sensitivity. The power transmission takes place maintaining a stable balance without disturbing torques, thus ensuring fatigue-proof working. The instruments are applied in perpendicular direction to the cavity margins, as the geometry of the diamond-coated working ends of the instruments conforms to the intended edge angle (Red) surface without diamond-coating on the instrument working end allows for a guided application while using the neighbouring tooth as supportive structure
