Abstract
A mandibular distractor can include an elongated main body having a central longitudinal axis extending in the elongate direction between a first end and a spaced apart second end. A first bone mount can be secured to the main body and a second bone mount can be positioned on the main body. A drive mechanism configured to selectively move the second bone mount longitudinally along the main body can also be included. A third bone mount configured to be moved longitudinally along the main body can also be included.

A mandibular distractor comprising:
- an elongated main body having a central longitudinal axis extending in the elongate direction between a first end and a spaced apart second end;
- a first bone mount secured to the main body;
- a second bone mount positioned on the main body, wherein the second bone mount includes an engaging member and a bone plate hingedly attached to the engaging member, the bone plate being configured to attach to a second bone portion;
- a drive mechanism engaged to the engaging member and configured to selectively move the second bone mount longitudinally along the main body;
- and
- a third bone mount associated with the main body, and configured to be moved longitudinally along the main body.

A method of performing distraction osteogenesis, the method comprising:
- providing a mandible extractor comprising:
- an elongated main body having a central longitudinal axis extending in the elongate direction between a first end and a spaced apart second end;
- a first bone mount secured to the main body, the first bone mount being configured to attach to a first bone portion;
- a second bone mount positioned on the main body, the second bone mount including:
- an engaging member;
- a bone plate hingedly attached to the engaging member, the bone plate being configured to attach to a second bone portion;
- and
- a drive mechanism engaged to the engaging member and configured to selectively move the second bone mount longitudinally along the main body;
- attaching the first bone mount to the first bone portion, the first bone mount being secured to an the elongated main body of the mandibular distractor, the main body having a central longitudinal axis extending in the elongate direction between the first end and the spaced apart second end;
- attaching the second bone mount to the second bone portion, the second bone mount being positioned on the main body;
- attaching a third bone mount to the second bone portion, the third bone mount being associated with the main body;
- and
- activating a drive mechanism to selectively move the second bone mount longitudinally along the main body away from the first bone mount, thereby causing the second bone portion to separate from the first bone portion.
