Optimal cavity wall treatment for adhesive restorations.

To best preserve the dental tissue and the pulp, an optimal cavity wall treatment is essential for taking full advantage of adhesive restorations. After analyzing the reasons for discrepancies between the results from laboratory and clinical studies, competing techniques of cavity wall treatment are evaluated. It is concluded that etching both the enamel and the dentin simultaneously, immediately coating with the chemically adhesive bonding agent, and placing the composite (without cement lining) is the simplest, surest, and most biologically protective technique.

Total etch technique and cavity isolation.

In the total etch technique for chemically adhesive composite restorations, the phosphoric acid penetrates only 10 microns or less into the vital dentin with the dentinal tubules being filled with the odontoblast processes. The acid is completely removed by subsequent air-water jet spray washing. The tubule apertures are perfectly sealed by the protective bonding agent layer with the resin tags adhering to the tubule walls and the resin-impregnated dentin surface. Isolation of the cavity from moisture contamination is required for only less than a few seconds after drying the etched cavity until the bonding agent coating and after this coating until the composite resin placement. Such a short time for isolation is quite easy even without a rubber dam when a trained assistant is cooperating.

Bite forming of occlusal composite restoration.

The bite-forming technique of posterior composite restoration is presented. Before preparation, the tooth surface is coated with a separating varnish. The occlusal anatomy of self-cured composite is bite formed by bare opposing teeth. Subsequent finishing is considerably simplified by the ability to peel excess composite from the varnished tooth surface. Finishing and detailing are further simplified by use of top-cut and top-safe superfine diamond points. A "free matrix" is used for Class II restorations.
