Disclosed are a bone mounting bracket capable of being fixed to maxilla by a screw and a palate expanding device including the bracket and a base unit supported by the bracket. The base unit includes a base body extendable to left and right sides and legs formed in the base body and transmitting a maxilla expanding force generated by the base body to the bracket. The bracket includes a leg mount with a leg assembling groove fixated to the maxilla by the screw and enabling the legs to be mounted. According to the present invention, the base unit is installed after the bone mounting bracket is mounted in a jawbone, and thus the palate expanding device is capable of being rapidly and easily installed. Accordingly, pains and burdens to a patient can be minimized. In addition, the bracket and the screw can be stably coupled regardless of directions of the legs being connected, and thus the stability of a maxilla expanding procedure, that is, the maxilla expanding procedure, can be secured, and the expanding force can be stably applied to a lateral side (slope) of the maxilla.

The present invention relates to an orthodontic device for moving maxillary teeth. The present invention corrects upper jaw molars and anterior teeth by moving molars and the anterior teeth forward and backward unlike existing orthodontic devices widening the palate portion, septum, and nasal cavity in a left-right direction. The present invention includes: a body (10) attached to a bottom surface of the gum of the upper jaw; a connection leg (20) having one end extending from the body (10) in connection thereto; a molar fixing portion (30) connected to the other end of the connection leg (20) and inserted into the molar; and a ring portion (40) connected to one side of a lower surface of the body (10). The body (10) is divided into a first body (11) and a second body (12). Gap adjustment is performed by the first body (11) and the second body (12) being separated from each other or approaching each other in an incisor direction and an airway direction of the upper jaw.

The present invention provides a dental impression bite tray having a disposable pad which contains an impression material and can be removed after a molar impression is obtained by using a dental impression bite tray. The dental impression bite tray comprises: a U-shaped tray body having pad entrances in both sides to attach a pad and having a coupling protrusion formed in one side thereof to fix support pieces in top and bottom sides of the pad entrances; and a handle body having a support piece. In the U-shaped tray body, a hanging unit formed by winding both ends of a disposable pad for accommodating an impression material and a support unit for preventing overflow of an impression material in the center thereof are formed by coupling an extension piece coupling hole formed in an extension piece formed in the center of the pad. The support piece includes a groove for accommodating the hanging unit formed on the pad by being coupled with the pad entrances formed in the U-shaped tray body, and a coupling groove formed to be coupled with the coupling protrusion formed in one side of the U-shaped tray body. The dental impression bite tray according to the present invention can obtain a molar impression and can conveniently remove and abandon an impression material and a disposable pad, so convenience can be remarkably improved when an impression material is removed. Also, only left and right needed parts of a molar can be selectively impressed. Moreover, only a U-shaped tray integrally formed with a disposable pad or a pad can be replaced, so waste treatment can be minimized. Accordingly, environmentally-friendly properties and economical profits can be pursued.
