At present, no man-made restorative can match the biologic acceptance of a hygienic natural tooth surface. Ideally, no restorative material would approach the gingival apparatus. However, as case demands often dictate violating this ideal, careful adherence to the principles discussed will minimize the damage to the periodontium. Ultimately, the response of the periodontal tissue will give the final approval or disapproval of any restorative procedure. The principles discussed must be considered at all phases of any restorative procedure. They must always be of primary concern.
