ABSTRACT:
The adhesive bonding of a pontic tooth to the two adjacent, natural abutment teeth is improved, particularly in resistance to shearing forces, by an improved adhesive bonding system. In this system, adhesive is applied to the previously prepared surfaces of the abutment teeth, and a thin screen or perforated film or foil is embedded in the adhesive on each tooth surface, conformed to the shape of the prepared surface, and penetrated by the adhesive. In one preferred embodiment, the adhesive wets and penetrates the surface of the artificial pontic that is being secured in place, the previously prepared abutment tooth surfaces, and the screens or films or foils, so that upon curing, an integral mass results that is mechanically strong, particularly in resistance to shear. The system is useful with natural or artificial teeth, can be used to install fixed bridges, and is useful for splinting.
