An experimental reinforced zinc oxide-eugenol cement of compressive strength 8,000 to 9,200 psi (562 to 647 kg/sq cm) was studied clinically for the final cementation of all types of inlays, crowns, and bridges. Patients were recalled and their teeth were examined for loose restorations and symptoms of leakage. Success rates of 94.4% for single restorations and 93.6% for bridge retainers justify further clinical use of the cement.
