Butt joint versus bevelled gold margin in metalceramic crowns
J Biomed Mater Res.
1980 May.
Abstract
The merits of a butt joint versus a bevelled margin are reexamined. It is shown that only acute bevels are effective in reducing the marginal diffusion of plaque acid. However, acute gold bevels may give rise to other major problems in avoiding distortion of the gold during firing of the procelain, and finishing and cementing the crown.
