A universal direct bonding system for both metal and plastic brackets

Abstract A new system of direct bonding has been described, and a step-by-step procedure as utilized at the present time has been outlined. Changes are occurring rapidly in the technique, and these changes will bring a greater percentage of success. Now in progress are basic studies of an electron scanning analysis of the NuvaSeal junction and the enamel and of the adhesive and NuvaSeal. Other studies will determine the effect of NuvaSeal application on the sheen on the enamel surface after removal of the NuvaSeal preparation. Clinical use may be somewhat empirical until these and other basic studies have been cempleted.
