STRATEGY CLEAR CAPS FOR DUPLICATION TECHNIQUE (STANDARD RETENTION) OT STRATEGY attachments are the only attachments of this type to have a (patented) parallel support under the sphere that automatically aligns the retentive caps, an important factor for the insertion of the prosthesis. It will determine the duration of the caps and prevent the risk of wear to the spheres. The reduced dimensions of these attachments permit them to be applied in very small areas making them perfect for removable prostheses, however they must always be accompanied by adequate milling. In cases where milling is not preformed, it is advisable to use the optional STEADY accessory.
