The final restorations are inspected for marginal fit and evaluated on the master dies. The patient is anesthetized, and the provisionals are carefully sectioned so that the underlying tooth structure is not damaged. The preparations are cleaned with a chlorhexidine scrub and each individual restoration is tried on the respective tooth to appraise the marginal fit. All of the restorations are tried-in with a glycerine based color matched tryin gel to evaluate the final value of the 'cemented' restorations and to verify the interproximal contacts. After the patient has given verbal approval each restoration is washed, dried and treated on the intaglio surface with three percent hydrofluoric acid which then is washed off and dried after the requisite time has passed. The teeth themselves are treated with 35 percent phosphoric acid which is washed off after 10 seconds on dentin and 30 seconds on enamel. The ceramic is treated with a silane wash and adhesive while the teeth themselves are coated while wet with a dentin/enamel adhesive system. The restorations are loaded with light-cured resin cement, seated, held into place, and excess cement is cleaned off. Each restoration is tacked cervically at the midface of the individual restoration. Proper cleaning of the interproximal surfaces are critical. Careful flossing of the interproximal area of the centrals ensures minimal finishing postcuring. The laterals and the cuspids are then cemented with the same technique. The restorations were light-cured for 2-3 minutes each. Final cement clean-up followed by occlusal adjustments under water spray and final polishing are then completed (Fig. 7).
