A system, components and methods is described to enable the treatment of maxillary deficiency and craniofacial dystrophy by positioning the maxilla via protraction forces applied extra-orally to skeletal anchorage devices embodied as bone anchors. The protraction forces are applied with minimal or no rotational moments being applied at the bone anchors. The shape and geometry of the bone anchors can be customized to fit the particular skeletal of individual patients.

The invention relates to a plate distractor, particularly a maxillofacial plate distractor, comprising a first (12) and a second (14) fixing plate, a threaded pin (24) mounted in a freely rotatable and translatably fixed manner in relation to the first fixing plate (14), a screwed tube (26) fixed to the second fixing plate (12), a permanent magnet (20) extending in a main direction, which is magnetised transversely to the main direction and mounted in the plate distractor (10) such that the rotation of the magnet (20) on itself, about an axis of rotation (D) parallel to the main axis, causes a relative rotation of the threaded pin (24) in relation to the screwed tube (26), the magnet (20) being arranged close to one of the ends of the plate distractor (10).

A bone distraction device having a ratchet and pawl assembly such that incremental rotation is allowed in one direction and prevented in the other, and further having a quick release mechanism such that the ratchet and pawl mechanism can be released to allow free rotation in both directions. The device has a pawl housing mounted onto a rod housing, the pawl housing having a sloping transition shoulder diminishing to transition onto the outer surface of the rod housing. In other embodiments, the device has a sleeve housing with an enlarged end telescopically mounted onto a rod housing, the enlarged end having a sloping transition shoulder diminishing to transition onto the outer surface of the sleeve housing.

A force adjustable spring distractor device having an elongated, relatively thin guide plate, a force adjusting rod member having first and second oppositely threaded portions, first and second anchor bodies mounted on the guide plate and the threaded portions of the rod, first and second distractor bodies mounted on the guide plate and the rod, and first and second distraction springs connecting the anchor bodies to the distractor bodies, whereby rotation of the force adjusting rod results in separation of the anchor bodies and elongation of the distraction springs, thereby imparting a separation force to the distractor bodies.

Systems, methods, devices and apparatus for mandibular advancement or retraction via bone anchoring devices are described herein. In various aspects, an apparatus for treating a patient via mandibular advancement or retraction comprises a plurality of anchoring devices positioned in the patient's intraoral cavity. Each of the plurality of anchoring devices can be positioned in bone of the patient's upper jaw or bone of the patient's lower jaw. One or more connecting structures can be removably coupled to and extend between the plurality of anchoring devices in order to displace the lower jaw anteriorly or posteriorly relative to the upper jaw.

The presently disclosed subject matter provides systems and methods to enhance fascia closure using surgical mesh products. An apparatus for performing distraction osteogenesis, the apparatus can include a first device that is fully implanted under the skin of a patient. The first device can include a distraction element configured to perform distraction osteogenesis on a bone to which the distraction element is attached and a first magnetic element connected to the distraction element. The apparatus can include a second device that is placed outside the skin of the patient. The second device can include a second magnetic element configured to transfer magnetic torque to the first magnetic element, resulting in the distraction element to perform distraction osteogenesis. The second device can include a processing circuitry configured to control operation of the second magnetic element.

A bone distractor device and method of bone distraction in osteogenesis, the bone distractor having releasable bone plates, created using computer-aided design to conform to the surface of a bone, attached to a distraction mechanism, wherein the distractor device is affixed to the bone, the distraction mechanism is removed from the bone plates, the osteotomy is performed using a guide edge provided on at least one of the bone plates, and the distraction mechanism is re-attached to the bone plates such that distraction can be initiated.

An external distraction apparatus for performing a craniofacial distraction is disclosed. The external distraction apparatus may comprise a stationary member. The stationary member may be configured to be affixed to a head of a patient. The external distraction apparatus may also comprise laterally disposed distractors. The laterally disposed distractors may extend inferiorly from the stationary member and be moveable relative to the stationary member. The external distraction apparatus may comprise a motor and controller. The motor may be powered with the controller to perform a craniofacial distraction in an automated fashion.

A distractor device may include a tubular body being internally threaded, a first foot plate extending from the tubular body, and an internal post in the tubular body. The internal post may include a first portion having a first diameter being externally threaded to cooperate with the internally threaded tubular body, and a second portion coupled to the first portion, having a second diameter less than the first diameter, and also being externally threaded. The tubular body may include a longitudinal slot extending from adjacent the first foot plate. The distractor device may include a second foot plate extending through the longitudinal slot and for threadingly coupling to the externally threaded second portion of the internal post. The second portion may include a tool interface on a distal end thereof.

A maxillomandibular fixation (MMF) device having an arch bar with a plurality of spaced tabs and gaps, and further having apertured mounting plate members mounted onto the arch bar, each mounting plate member having a slot to receive a tab on the arch bar, whereby the mounting plate members may be repositioned laterally along the arch bar from one tab to another prior to affixing the MMF device to the maxilla or mandible of a patient in order to position the mounting plate members at locations where the underlying tooth root will not be damaged by insertion of a bone screw.
