[Kinetics and stress distribution of supported free-end prostheses. I. Effect of the frame stability on the kinematics of the saddle and the stress on the edentulous prosthesis bed].

By means of inductive pressure and motion recorders, the influence of the stability of the framework, the extension of the saddle and type and location of anchorage on the kinetic properties of the denture and the distribution of load between edentulous base and abutment teeth was studied in three different free-end dentures. The findings are discussed with respect to the planning and technical design of dentures.
