Connecting bar Milled bar
Design (cross-section) See Figure 2 - Hader - Dolder (ovate) - Ackermann (ronde) - square - rectangular - L-shaped - rectangular - ovate
Thickness 1 to 2 mm < 2mm
Material
- titanium - cobalt-chromium - PEEK - fiber-reinforced resin - zirconia - titanium - cobalt-chromium - PEEK - fiber-reinforced resin - zirconia
Fabrication process
- cast - machined - milled - machined - milled
Number of implants 2 to 6 implants 3 implants or more
Female part Clips and retention devices (plastic or brass) - counterbar and retention devices (plastic or brass)
Type of prosthesis Removable prosthesis with mucosal support Removable prosthesis without mucosal support
Mechanical behaviour
- tissue duality - rotation around the CB if 2 implants - 0 degré of liberty - no tissue duality - behaves like a fixed implant-retained overdenture - behaves like a fixed implant-supported prosthesis
