Abstract

Background:  For many years, removable partial dentures have been designed from a pure mechanical point of view only to fail through a lack of appreciation of the biological factors involved. This is especially true in case of distal extension partial dentures. In these cases, support is provided by tooth on one end and mucosa covering the bone on the other end. This causes an uneven or unequal balance of movement leading to undue stresses on abutment teeth and residual ridge because the mucosal support allows more movement of the prosthesis than does the tooth supported portion of the prosthesis. The magnitude and direction of stresses will depend on the type of partial denture and the design of its parts in relation to the anatomic and functional form of the supporting structures. By means of precise diagnosis, treatment planning and designing of partial denture, the stresses can be optimized within physiological limits.
