Abstract
A new simple modification method for adherend metals surface by using liquid Ga-Sn alloy (Adlloy) was investigated to applicate for the precious metal alloy denture. Surface of silver based alloy containing 12 wt% gold was modified by Adlloy and applied 4-META resin. The adhesive ability was studied by percolation tests and shearing bond strength, and compared with the results of tin electroplating method.
The surface modification by Adlloy showed lower percolation ratio and higher shearing bond strength than tin electroplation method, suggesting that the method is effective for application to precious metal denture and would prevent percolation of salivary and food debris at the finishing line of denture.
