The collarless metal-ceramic crown.
A technique has been developed whereby collarless metal-ceramic crowns can be fabricated by spot-welding the platinum-foil matrix to the casting after it has been contoured for porcelain application. The main advantage of this procedure over previously reported techniques is that it produces well fitted restorations while requiring a lesser degree of technical skill.
