Four or more standard size implants are strategically placed and joined by bars that are screwed down to the implants forming a frame. The denture has retention clips that fit over the bar usually in 2 - 4 places. In this case the denture rests upon the bar and is passive to the gum and bone tissues.
Dentures supported by bars can typically allow 50 - 60 % of maximum chewing force (based on natural teeth)
Dentures are removed for cleaning. Implants and bars require cleaning with brush and floss with moderate effort needed. As with any Implant, professional exam and cleaning are recommended every 6 months and in some cases every 3-4.
