摘要：
A denture is fitted with a magnetic assembly and an operatively associated keeper. The magnetic assembly is characterized by having a magnet sandwiched between two pole elements and the pole elements and keeper are shaped with mating curved surfaces. An occlusal stop located on the keeper prevents the magnetic assembly from sliding off the keeper and prevents air gaps between the magnetic assembly and the keeper.
