The plane guide plate is rectangular sheet, the side length of the near-far middle-direction is 8-10mm, the side length of the sagittal direction is 3-4mm, and the thickness (the vertical side length) is 1-1.5 mm.
Preferably, two traction columns are arranged and are respectively connected with the positions of 1-1.5mm left and right of the middle point of the arc-shaped main body. The midpoint of the arc-shaped main body is positioned at the vertical height and is preferably positioned in the root of the maxillary canine root, so that the canine can realize integral movement and avoid inclined movement.
The diameter of the arc main body is 1.5-2mm, and the arc main body can be arc-shaped or elliptic arc-shaped.
The manufacturing and using method of the invention is as follows:
(1) and taking the upper and lower models, the corresponding occlusion records and the upper jaw frame for the patient.
(2) An orthotic appliance to assist extension and retraction of the mandible into the upper anterior teeth is designed. The guide rod is positioned 1-2mm in the gingival margin crown of the lower anterior tongue side, the diameter is 0.8-1.2mm, the guide rod is adapted to the shape of the side surface of the lower incisor tongue of a patient, and as shown in figure 1, the shape of the guide rod is approximate to a herringbone shape. The guide rod is connected with the plane guide plate through a second connecting rod. The plane guide plate is positioned on the palatal side of the upper jaw and incisors and is occluded with the lower incisors. When the lower incisors of the patient are occluded with the plane guide plate, the plane guide plate is positioned 2-3mm in the root of the incisal margin of the upper anterior teeth (middle incisors), the width in the proximal-distal direction is 8-10mm, the width in the sagittal direction is 3-4mm, and the thickness is 1-1.5 mm.
(3) An attachment part corresponding to the lateral surface of the cuspid tooth tongue is designed, the arc main body of the bracket is semicircular, the diameter of the arc main body is 1.5-2mm, the arc main body is 0.5-1mm away from a mucous membrane, and the midpoint of the arc main body is vertically positioned in the root direction of the upper cuspid tooth root. The arc main body is provided with traction small columns in the direction close to the middle occlusal direction at positions 1-1.5mm away from the left and right of the midpoint of the arc main body respectively, the length is 3-4mm, and the diameter is 0.5-0.8 mm. The traction column is provided with a groove which can be used for fixing a rubber ring, so that the vertical position of a stress point can be conveniently adjusted, and finally the moving mode of teeth can be adjusted.
(4) One micro-implant anchorage nail is implanted at the position 1mm from the left and right of the median palatine suture, and the sagittal position of the micro-implant anchorage nail is positioned on the connecting line of the left and right first molars.
(5) The bracket is bonded by fluid resin, the connector is bonded on the palatal side of the maxillary canine, the plane guide plate is on the palatal side of the upper middle incisor and occluded with the lower front teeth, the guide rod is abutted against the lingual side of four lower incisors (the lower middle incisor and the side incisors), and the force is applied by a chain-shaped rubber ring. In this way, mandibular distraction and canine distal movement can be achieved simultaneously.
(6) After the maxillary canine teeth move backwards and the anterior teeth are scattered in gaps, the upper anterior teeth are fixedly corrected (in the process, the device is not detached). The bonding brackets in the anterior dental area are aligned using niti wires. After the anterior teeth are aligned, the six anterior teeth of the upper jaw are stably connected, and finally the whole adduction of the six anterior teeth of the upper jaw is realized. In the process of adduction of the upper jaw, the lower jaw is treated correspondingly, the lower jaw is aligned and leveled as soon as possible, and the lower front teeth are taken as a whole, so that the side effect on the lower front teeth is reduced.
(7) When the whole fixed correction is carried out, the lower jaw is still in the extending position because the device is still used, so that the reconstruction of the condyles is facilitated, and the effect of functional correction is realized. Meanwhile, the occlusal plate designed in the anterior teeth area is beneficial to the opening of the whole occlusion.
(8) The guide rod applies labial force to the lower anterior teeth, so that anchorage of the lower anterior teeth is enhanced, the lower posterior teeth are pulled to move forwards, and adjustment of molar relation is facilitated.
