Description

TECHNICAL FIELD [0001] The present invention relates to a fixation holder for a mandible extension device, a method for manufacturing the same, a recording medium,

[0001] The present invention relates to a holder for fixing a mandible holder, a method of manufacturing the same, a recording medium, and a manufacturing apparatus, and more particularly to a mandrel holder having a small size, A mandrel extension device fixation holder including a fracture end guide capable of fixing the jawbone extension device in such a manner that the jawbone extension device can be extended in a precise position when it is extended, a mandrel extension device fixation holder not including a fracture end guide, Media and jawbone extension device holder holder.

Among patients with craniofacial anomalies, both sides of the maxilla or mandible or one side may exhibit abnormal thermal growth. Especially, when the congenital anomalies such as hemifacial microsomia and congenital anomalies such as cleft lip & palate are overlapped with each other, the heat field of the jaw is very severe.

Among the various facial deformities, there is osteogenesis as a surgical treatment of the maxillary and mandibular bones showing the above thermal growth. This treatment is a way to increase the length of the mandible or maxilla by thermally growing the bone with a small amount of bone every day using a stretching device to increase the length of the maxilla. At this time, the stretching direction of the jawbone is very important, and proper treatment of the face and occlusion depends on it.

Distraction device for jaw bone for maxilla and mandible etc. can be divided into extracorporeal extension device and intraoral extension device. The extracorporeal elongation device is a device that is installed to expose the jawbone extension device from the face and adjusts it from the outside. It has the advantages of simple installation, easy operation, and adjustable extension direction. However, it is inconvenient for social life, And there is a possibility of leaving scarring.

On the other hand, the intraoral oral elongation device is a device in which the jawbone extension device is mounted in the oral cavity, and is recently widely used because of the disadvantages of the oral external device. However, since the control part of the intraoral device is in the oral cavity, problems such as discomfort in chewing activity and difficulty in controlling the direction of extension may occur.

The direction of osseous extension in the jawbone renal technique using the intraoral extension device is almost all determined by the position and the angle of the osseous stretching device determined by the installation of the osseointegration device. In general, the direction of the jawbone can not be properly controlled because of erroneous treatment planning, erroneous positioning of the device and orientation setting in the surgical procedure. In this case, the maxilla and mandible are extended to the wrong position, resulting in abnormal shape of the face and at the same time functional problems such as malocclusion may occur.

Accordingly, the present invention is directed to a method and apparatus for expanding a small, posteriorly placed mandible using a device for jawbone extension, which is thermally grown and has a precise orientation and can fix a jawbone extension device at a precise position, A device holder holder, a mandrel holder holder without a fracture end guide, a method of making the holder holder, a recording medium, and a mandrel holder holder holder holder.
