We illustrate the importance of bridge geometry and connector design taking a typical all-ceramic 4-unit bridge as an example (Fig. New all-ceramic, ... To be sure the bridge will not fracture, each connector must have a calculated number of 27 or higher. Zirconia? Do you think it was an occlusal issue? The connector of the Maryland bridge is highly susceptible to fracture due to the wedge-shaped geometry created by the gingival embrasure, the thinness of the material where the pontic meets the wing, and the concentration of stress due to the cantilever of the pontic. Full-contour zirconia was chosen because of its high flexural strength and higher fracture toughness; it also provided the dentist with the ability to conventionally cement the bridge. Therefore, Increasing the connector size could affect aesthetics and functionality. The sinter process effects a shrinkage of 20%. Is It Time To Get An Intra-oral Impression Scanner?
