Abstract
In the second report, it was found that the adhesion bridges and splints prepared by a method of electrohydraulic wire explosion could be sufficiently applied in clinical cases. In this report, therefore, the methods for promoting the adhesive strength of the adhesive resin (Panavia) to metal base were discussed. And it was examined whether the components of the two Ni-Cr alloys base metal affected of not the adhesive strength.
The mean adhesive strengths of Panavia under shear to Ni-Cr alloys were relatively small compared with Super Bond C & B. Furthermore, there was difference in the shear strength between the two Ni-Cr alloys.
However, the shear strengths were 110.0-154.3 kg/cm2From these results, it can be seen that the property of Panavia is clinically favourable since it is considered that Panavia has some surpassing features-the thin capsule of 19μ thickness, the easy manipulation, and the low adsorption. And it can be found that the surface treatment by electrohyraulic Ni-Cr wire explosion is clinically favourable irrespective of the compornents of Ni-Cr alloys.
