How do basal implants work?

Basal implants can be compared to an inverted one-legged stool. They transmit the load through the seat end, the masticatory load being guided through a crown that is attached to the pin (the leg of the stool, to stay within the metaphor) of the baseplate (the seat).
The pin, at its upper end, features a thread designed to hold a small cylinder (abutment) to which the crown is attached. The masticatory load acts on the threaded pin and is transmitted through the bar attachment that passes through the annular (ring-shaped) baseplate to the surrounding bone (Figure 7).
Part of the compressive forces of mastication is converted to tensile forces similar to the forces acting on the natural periodontal tissues.
