Description

Maxillary Skeletal Expander Using Curable Resin The present invention relates to an arch expansion device using a curable resin. An arch expansion device is a device used to treat patients in whom the upper jaw is less developed than the lower jaw; it is designed to expand the upper jaw to facilitate treatment. Facial bones are structured like a puzzle, making them easy to move during the growth period; the upper jaw is also not composed of a single bone but consists of multiple interlocking bones. When the upper jaw is too small to accommodate permanent teeth, it is possible to widen the arch itself by opening the bony region in the center of the palate. FIG. 1 is a perspective view illustrating an arch expansion device using a mini screw according to the prior art, and FIG. 2 is an exploded perspective view of FIG. 1. Looking at the configuration, it consists of a pair of main bodies (100), an expansion screw (300) for adjusting the distance between the pair of main bodies, a guide rail (400) for guiding the movement of the main bodies and having both ends inserted into the pair of main bodies, a key hole (500) formed integrally with the expansion screw, a screw insertion part formed integrally with the main body and having a screw insertion hole for guiding a micro screw implanted in the upper jaw, an arm (200) with one end fixed to the main body and the other end extending toward the tooth, and a tooth fixing part (600) formed integrally with the arm and fixed to the patient's tooth. These conventional arch expansion devices have the problem of increased procedure costs and delayed treatment time because the gap between the main body parts is limited by the bolt length of the expansion screw, requiring the inconvenience of replacing the screw with a longer one if further expansion is desired. FIG. 1 is a perspective view illustrating an arch expansion device using a mini screw according to the prior art. Figure 2 is an exploded perspective view of Figure 1. FIG. 3 is a perspective view illustrating an arch expansion device using a curable resin according to one embodiment of the present invention. Fig. 4 is an exploded view of Fig. 3.
