Bar Coping abutments are titanium, non-engaging cylindrical posts are designed to seat directly into the implant or intermediate abutment that are laser-welded to titanium bars to create an all titanium bar or bridge framework. Implant bar restorations mostly have a minimum of two to five implants. In an ideal situation, hader bar and retentive clips are used in the anterior, whereas locking pin attachments are located distally for support and stability. The laser-welding technique eliminates the need for casting, waxing, investing, and finishing. The ideal implant bar system incorporates a bar and retentive clips in the anterior section and locking pin attachments distally for support and stability.

Note: This product uses a 0.050" Hex Screw Driver.
