A device for correcting and fixing the palate of the dentition, used together with the correction line, is an arched metal transversely extending bridge, and a nail fixing plate with several through holes is formed in the middle section, so that the nail can be penetrated through the through hole to fix the nail The fixed plate is nailed to the upper jaw of the patient's mouth, and the arched arm is extended integrally at both ends, and at least one through sleeve is formed at the end of the arched arm, and the correction line is inserted into the posterior tooth gum through the sleeve through the two sides The two sides correspond to the tail section of the line, and the dentition is corrected by the bracing and guiding correction lines, and more on the nail-fixing plate surface facing the upper jaw, several bamboo shoots are protruded vertically and staggered through the positions of the through holes, and arched on both sides. The arm of the shaped bridge faces the front edge of the arm, and at least one T-shaped hook is protruded to hook the end of the elastic traction member connected from the middle of the correction line to the back of the upper jaw. Avoid the practice of nailing from the upper jaw of the upper row of roots to connect the fixing structure of the tail of the orthodontic line. Due to new symptoms such as inflammation, long polyps, and gum wounds on the upper jaw of the upper row of roots, the orthodontic surgery effect is poor or even The lack of failure, and the gap between the nail fixing plate surface and the upper jaw is opened by the bamboo pile top, so that the nail attachment part is ventilated and comfortable, and the person who is uncomfortable with the nail attachment of the nail fixing upper jaw member is learned.一種用於齒列矯正固定腭部裝置，係與矯正線一同使用，為一拱形金屬橫伸橋接件，其中段形成開設有數透孔之釘固板，以便用骨釘貫穿透孔將釘固板釘至患者口腔上顎，而兩端分別一體延伸出拱形橋臂，並於拱形橋臂末端形成至少一個穿套管，藉由兩側穿套管套入矯正線伸入後齒牙床之兩側對應線尾段，以架撐、引導矯正線進行齒列矯正，且更於朝向上顎之釘固板面上，錯開透孔位置凸豎伸出數枚筍樁，又於兩側拱形橋臂朝向前齒之臂緣邊上，凸設至少一個T形掛勾以勾定從矯正線中間部位往上顎後方
