Described herein is a reinforcement bar combination for a direct dental bridge, the reinforcement bar combination comprising: first and second elongate bars, each of the first and second elongate bars contacting a single occlusal preparation formed in a single abutment tooth and each of the first and second elongate bars having an end positioned on a central pad of a third elongate bar to form a reinforcement scaffold. The first elongate bar is a first elongate torque bar that is optionally bent. The second elongate bar is a second elongate torque bar that is optionally bent. The third elongate bar is a proximal bar comprising a central planar pad bound by a perimeter, a coronal facing surface and an apical facing surface, a first insertion arm extending in a mesial direction from the perimeter of the pad, a second insertion arm extending in a distal direction from the perimeter of the pad; a first vertical sidewall extending in a coronal direction from the coronal oriented surface of the pad; a second vertical sidewall extending in a coronal direction from the coronal oriented surface of the pad. Method of use of the reinforcement bar combination to produce a direct dental bridge is also described. |
