Strengthening mechanism of bonded alumina crowns.
The results of this study suggest that the strengthening of aluminous porcelain with Sn-plated Pt is an effect of (1) a chemical interaction involving diffusion and dissolution of Sn-oxide in the glass phase of the porcelain and (2) a better wetting of te Sn-plated substrate by the porcelain. This conclusion supports and confirms the earlier hypothesis of McLean and Sced.
