' As the distance from the denture base to teeth increses, the associated radius(arc of rotation) also increases and arc of rotation become linear, hence anterior placement of rest help direct the forces more vertically onto the tissues of the ridge' WHAT DOES THIS STATEMENT MEAN SIR?
Ok it means if instead of distal rest you take mesial rest then distance from denture base is increased. So as you move away then you have better mechanical advantage because of more favorable arc of rotation you have better denture stability.
Sir in class 1, Since the posterior teeth are edentulous All the load are on the abutment teeth I didnt understand the fact how you distribute load equally
Load is shared between abutment and edentulous ridge. Greater edentulous span has more load share by ridge and less by abutment and vice versa. For stability balance is required.
Thank u sir
