The OT Vertical bi-cylindrical friction attachment is suitable for use with partial dentures and combination cases as well as bar connections. The cast metal quide pin is necessary to center, connect and balance the prosthesis during the final insertion. When milling or "cross-arch" stabilization are not possible, the guide pin along with the NEW "Steady" will provide lateral stability to the prosthesis. This ensures a longer life for the retentive clips.
The vertical height of the attachment can be adjusted by reducing both male and female parts from the original length of 5 mm down to 2.5 mm according to the pre-marked notches. Reducing the vertical height creates no difference in functionality. Removal and replacement of clips can be easily performed by the Dentist chairside.
