  The increased emphasis on physical appearance in contemporary society has increased the demand for esthetic dental treatment. The metallic color of the buccal clasp arms on premolars or canines is one of the common causes of patient rejection. The appearance would be vastly improved if the buccal clasp arms were eliminated. However, the retentive function of clasps eliminated buccal clasp arms is extremely poor. We developed a new retainer of no buccal clasp arm with the magnetic attachment in the occlusal rest of clasps (Magnetic Rest Clasp).
In this study, we introduced the fabrication of a new retainer gMagnetic Rest Clasph for porcelain fused to metal crowns on lower premolars with a plastic jaw model with artificial teeth.
The results presented in this paper, gMagnetic Rest Clasph was esthetic and had fine retention for partial denture.
