Apparatus for orthognathic surgical planning

An apparatus for orthognathic surgical planning, comprising:

• a base plate;
• an anterior plate;
• an anterior screw extending through the anterior plate, wherein the anterior screw includes a proximal end configured to be rotated by hand and a freely rotatable distal end anchored to at least one pillar extending from the base, wherein the anterior plate is linearly movable along the anterior screw by rotation of the anterior screw, and wherein a length of the anterior extends along an anterior-posterior axis;
• a first posterior plate;
• a first posterior screw extending through the first posterior plate, wherein the first posterior screw includes a proximal end configured to be rotated by hand and a freely rotatable distal end anchored to at least one pillar extending from the base, wherein the first posterior plate is linearly movable along the first posterior screw by rotation of the first posterior screw, and wherein a length of the first posterior screw extends along a transverse axis orthogonal to the anterior-posterior axis;
• a second posterior plate;
• a second posterior screw extending through the second posterior plate, wherein the second posterior screw includes a proximal end configured to be rotated by hand and a freely rotatable distal end anchored to at least one pillar extending from the base, wherein the second posterior plate is linearly movable along the second posterior screw by rotation of the second posterior screw, and wherein a length of the second posterior screw extends along the transverse axis.
