[Adhesive cast restorations].

The aim of this article is to present the clinical use of the adhesive cast restoration in the treatment of the advanced perio case in an effort to overcome the serious restorative problems related to those cases. The use of the adhesive cast restoration in the advanced periodontal conditions has proved that it can be considered a permanent restoration. The main advantages in the use of the adhesive cast restoration are: i) Minimal tooth preparation, which eliminates the possibility of pulpal contamination. In fact, pulpal integrity is of crucial importance in the advanced perio case because of the close interrelationship between the pulp tissue and periodontal structures. ii) Supragingival lingual margins, which do not compromise the patient's esthetics and permit for good plaque control. iii) Reversibility of the restoration. iv) Reduced cost, which helps the clinician to use teeth with guarded prognosis from a periodontal point of view.
