An extraoral orthopedic device for direct protraction of the maxilla and indirect protraction of the mandible of a patient, comprising a circular cranial support configured for placement around the periphery of the neurocranium of a patient encircling the forehead, two perpendicular girders adjustably coupled to the circular cranial support and extending in a downward direction on either side of the face of the patient, each of the two perpendicular girders having a plurality of openings extending diametrically therethrough and disposed distally relative to the circular cranial support; an intraoral mechanism disposed in the mouth of the patient; and a horizontal girder coupled through elastic tractions with the intraoral mechanism and adjustably supported within a respective slot of the plurality of openings in each of the two perpendicular girders.

The invention relates to a method for manufacturing at least one bone anchor and a corresponding drilling template, wherein the bone anchor has an anchor plate which is to be fixed to the surface of a bone by means of one or several screws having a screw head. The anchor plate thus has a bone side which is to connect to the surface of the bone and a free side which is opposite to said bone side. Further, the invention concerns a method for manufacturing a drilling template making it possible to make bore holes in the bone at predetermined positions and to screw the bone anchor to said bone according to predetermined orientations.

An assembly for correcting unbalanced growth plate activity including: (a) an implant formed of wire having (i) a longitudinal central section (2), (ii) a first end (3) configured as a first loop (4) in a form of a first helical coil (9) having a central axis (5) that is transverse to a longitudinal axis of the central section, and (iii) a second end (6) configured as a second loop (7) having a central axis (8) that is transverse to the longitudinal axis of the central section; (b) a first bone screw having a shaft section that is insertable through the first loop; and (c) a second bone screw having a shaft section that is insertable through the second loop. A kit for correcting unbalanced growth plate activity and to a method for correcting unbalanced growth plate activity are also disclosed.

A magnetic orthodontic device has two correction appliances. Each of the correction appliances has a linkage portion, a first connecting portion, a second connecting portion, an adhering plate, a neodymium magnet, and a shell. The linkage portion is elongated and has two opposite ends. The first and second connecting portions are respectively disposed at the two opposite ends of the linkage portion. The adhering plate is disposed at the first connecting portion. The neodymium magnet is disposed at the second connecting portion. The adhering plate and the neodymium magnet respectively protrude toward opposite directions. The shell surrounds the neodymium magnet. The neodymium magnets of the two correction appliances are capable of repelling or attracting each other.

Connectors for connecting or linking one instrument or object to one or more other instruments or objects are disclosed herein. In some embodiments, a connector can include a first arm with a first attachment feature for attaching to a first object, such as a surgical access device, and a second arm with a second attachment feature for attaching to a second object, such as a support. The connector can have an unlocked state, in which the position and orientation of the access device can be adjusted relative to the support, and a locked state in which movement of the access device relative to the support is prevented or limited. Locking the connector can also be effective to clamp or otherwise attach the connector to the access device and the support, or said attachment can be independent of the locking of the connector.

A medical apparatus including a bar with a first attachment loop, a second attachment and a plurality of hooks, wherein the medical apparatus is an arch bar.

The invention discloses a modular surgical bone screw assembly having a threaded base portion and a screw head adapted to attach a variety of structures to bone. The features of the screw include a modular design for the assembly that separates the function of anchorage to the recipient bone to one of the modules of the device (threaded portion) from the other function of attaching another element (such as bone block, membrane, orthodontic wires, elastics etc) to a second module (the screw head). The design also allows the head to be exchanged after the implant has been placed.

A removable orthodontic assembly to be used in a user's mouth, including: a frame member configured to be removably positioned proximate a lingual portion of the user's teeth; a first connector member, wherein the first connector member comprises a first end extending proximate to a labial portion of the user's teeth and a second end engaging the frame member; and a labial bow configured to be removably positioned proximate to the labial portion of the user's teeth having a first end and a second end, wherein the labial bow is configured to removably engage the first connector member.

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.

Disclosed are apparatuses and techniques for distalizing, mesializing and/or expanding teeth in the upper or lower dental arch of a patient's mouth to make room for crowded or protruded teeth located in the anterior arch region to distally and laterally shift into. In some aspects, an apparatus includes a body; a first arm coupled to an adjustment mechanism of the body and attachable to a molar; a second arm coupled to the apparatus body and attachable to a non-molar tooth; and an anchorage device attachable to a bone in the mouth, which the first arm is configured to transfer a force onto the molar when the adjustment mechanism is actuated to cause movement of the molar in the dental arch, and which the anchorage device is operable to positionally stabilize the body and the second arm to prevent movement of the non-molar tooth in the dental arch.
