The Channel Shoulder Pin Attachment

If the construction requires an attachment point in a still-complete dental row, then a groove-shoulder attachment can be used.
These are intracoronal horseshoe-shaped elements that are attached to the oral side of the crown (hiding them from view) to which the matching interlocking denture with mirrored elements can attach (see article 1 in the series "No Clasps Please!").
The secondary construction, as well as a stress breaker, is normaly made of high-quality gold alloy that is soldered with the model cast to guarantee a perfect and tension-free fitting (Note: you cannot exchange the male component within RSS).
