The versatile Vario-Snap SG attachment is a simple, yet effective extra-coronal attachment designed for removable precision partial dentures. The round male component is available in two diameters, 1.7mm for smaller areas such as the anterior and bicuspid regions, and a 2.2mm diameter for the molar area. It starts as a plastic pattern that is incorporated as part of a crown wax pattern and cast in a hard dental alloy. The versatile Vario-Snap SG can be positioned in a standard distal arrangement or at other aspects of the crown. The color-coded female inserts provide progressive degrees of retention and are easily replaced when worn. This system has proven itself time and again, due to its flexibility and reliable performance.
