Dental Dentures: Partial | Cosmetic Dentistry
If an axis connecting the last two remaining teeth in the arch forms a tangent, but this time a short tangent to the curve of the arch (Fig. 75), the following static situation results:
If the same side free-end saddle is subjected to a functional load, it will simply settle into position while anterior lifting forces are generated diagonally on the opposite side of the axis of rotation (Fig. 76).
A functional load in the anterior region will result in settling there and dist all lifting forces diagonally on the other side of the axils of rotation (Fig. 77).
If the side opposite the support axis is subjected to a functional load. the dental denture will rotate around this tangential support axis (Fig. 78). The denture is not definitively guided. Besides that, corresponding undercuts are seldom present so that retention also becomes
