A device for maxillary jawbone and dentition expansion and/or retraction is configured for mounting within the mouth and connects the right and left halves of the skull. The maxillary distraction device includes at least two implantable anchors configured to be implanted in the maxillary bones of the skull on opposite sides of a midline of the skull. A facebow having two posterior ends is connectable to the implantable anchors and is configured to extend from the maxillary regions entirely within the mouth across the midline of the skull. The facebow has at least one expandable section for bone lengthening. The facebow is connected to the anchors and is lengthen periodically to lengthen the maxillary bones. The facebow may provide horizontal, vertical, and transverse distraction.
Claims22
A maxillary distraction device comprising:
- at least two implantable anchors configured to be inserted into the bones of the malar region;
