Mandibular bone plate systems

A mandibular bone plate configured to be attached to a mandible that defines a buccal surface, a lingual surface, and an inferior surface that joins the buccal surface to the lingual surface, the mandibular bone plate comprising:

• a curved chin portion having a first end and a second end;
• and
• a first extension portion that extends from the first end along a first axis and is elongate along the first axis so as to define a proximal end that is proximate the first end and a distal end that is spaced from the proximal end along the first axis, the first extension portion defining a first bone facing surface, a first outer surface that is opposite the first bone facing surface, and a plurality of bone anchor holes that extend from the first bone facing surface to the first outer surface, the first bone facing surface having an inferior end and a superior end that is spaced from the inferior end along a direction that is perpendicular to the first axis, the first extension portion being oriented such that a line that is tangential to both the inferior end and the superior end of the first bone facing surface along the first direction at a distal portion of the first extension portion is rotated about the first axis relative to a line that is tangential to both the inferior end and the superior end of the first bone facing surface along the first direction at a proximal portion of the first extension portion so that the first bone facing surface is configured to abut at least a portion of at least two of the buccal, lingual and inferior surfaces of the mandible when the mandibular bone plate is attached to the mandible.
