Stresses in a cantilever metal-ceramic bridge in model experiments.
The stresses in the porcelain part of the last anchor crown in a cantilever bridge was analysed when loaded. The experiments were made with a model bridge. The load directions were vertical and horizontal. The critical load at the end of a four unit bridge was calculated to about 200 N. When the load direction was perpendicular to the axis of the pontic the critical load was estimated to 50 N.
