Detailed Description
In an embodiment of the present invention as shown in fig. 1, a classification measuring tool for maxillary impacted canine full-thickness curved fractured bone slice comprises: the device comprises a base frame 1, a measuring rod A2, a sliding head 3, a scale 5, a measuring rod B6 and a sliding sleeve 8; the base frame 1 consists of a rectangular bottom edge and an arc top with scales, and a semicircular opening is formed in the middle; one end of the measuring rod A2 is rotatably connected with the sliding head 3, the other end of the measuring rod A2 is rotatably connected with the center position of the bottom edge of the base frame 1, the sliding head 3 is clamped with the outer edge of the circular top of the base frame 1 and has a sliding gap, the measuring rod A2 is driven to rotate by the sliding of the sliding head 3 outside the circular top of the base frame 1 by taking the center position of the bottom edge of the base frame 1 as the center of a circle, and the measurement of the included angle formed by the long axis of the lateral incisors of the upper jaw and the long axis of the impacted apical incisors of the upper jaw on the same side and the apical; the measuring rod A2 is sleeved with two sliding sleeves 8, the sliding sleeves 8 can slide on the measuring rod A2, and holes in the two sliding sleeves 8 perpendicular to the measuring rod A2 are respectively sleeved with the scale 5 and the measuring rod B6; one end of the measuring rod B6 protrudes and is provided with a hole, the scale 5 is L-shaped, and the other end of the scale 5, which is far away from the sliding sleeve 8, is sleeved with the hole on the measuring rod B6; a telescopic rectangular structure is formed among the measuring rod A2, the scale 5 and the measuring rod B6 and is used for measuring the overlapping area of the images of the maxillary lateral incisors and the maxillary impacted canine teeth on the same side, and the measured area is approximated to be rectangular through a rectangular frame for measurement because the measured area is irregular; the inner side of the bottom edge of the base frame 1 is provided with a notch 7, as shown in fig. 1, when the measuring rod A2 moves to a position approximately parallel to the bottom edge, a telescopic rectangular structure is formed among the measuring rod A2, the scale 5 and the measuring rod B6, and can enter the notch 7 without influencing measurement.
Specifically, holes at two ends of the measuring rod A2 are respectively and rotatably connected with the central position of the bottom edge of the base frame 1 and the sliding head 3 through pins 4.
Specifically, the slider 3 comprises a slider frame 31 and a rubber wheel 32; two rubber wheels 32 are respectively arranged on the sliding head frame 31 side by side; the rubber wheel 32 runs on the outer side edge of the arc top of the base frame 1, so that the sliding head 3 slides on the outer side edge of the arc top of the base frame 1, and meanwhile, the outer side edge of the arc top of the base frame 1 is provided with texture for increasing friction force.
Specifically, the ruler 5 and one end of the measuring rod B6 sleeved with the sliding sleeve 8 are provided with a barrier 9, so that a telescopic rectangular structure formed among the measuring rod A2, the ruler 5 and the measuring rod B6 is effectively prevented from withdrawing from the sliding sleeve.
When in use:
placing the measuring tool on an image sheet, arranging the connecting line of the connecting part of the bottom edge of the base frame 1 and the two ends of the upper jaw and the lower jaw in parallel, horizontally moving the measuring tool to move the sliding head 3 simultaneously, moving the measuring rod A2 to the positions of the long axis of the upper jaw side incisor and the long axis of the upper jaw cusp obstructing tooth on the same side respectively to measure two angles, and subtracting to obtain the included angle formed by the directions of the upper jaw side incisor cutting end and the upper jaw cusp obstructing tooth;
the correction design that the positions of lateral incisors and impacted canities are exchanged more probably occurs when the theoretical overlapping area is smaller and more difficult to correct to the normal position is larger. When the included angle is 90 degrees or more (inversion inhibition) the difficulty of correction is extremely large.
Moving the measuring tool to enable a telescopic rectangular structure to be formed among the measuring rod A2, the scale 5 and the measuring rod B6 to frame the impacted canine teeth to measure the whole area, then measuring the overlapping area, and classifying according to the overlapping degree;
the overlapping degree is classified according to equal parts of the theoretical overlapping area of the maxillary impacted canine teeth in the image area of the maxillary impacted canine teeth. Level 1 overlap: the theoretical overlapping area is less than 1/4; level 2 overlap: 1/4 is less than or equal to the theoretical overlapping area which is less than 1/2; level 3 overlap: the theoretical overlap area is greater than or equal to 1/2. According to previous research and successful correction experience: when the upper jaw impacted cuspids are overlapped with the upper jaw adjacent teeth, the correcting difficulty is higher than that when the upper jaw impacted cuspids are not overlapped; when the upper jaw impacted canine tooth is overlapped with a plurality of teeth, the correction difficulty is higher than that when the upper jaw impacted canine tooth is overlapped with a single tooth; when the overlapping degree grade is 1 grade, the correction difficulty is simple; the difficulty of correction is moderate when the degree of overlap is ranked 2, extremely difficult when the degree of overlap is ranked 3, and the possibility of considering the interchange positions of the maxillary impacted canine and the lateral incisors is higher when the theoretical overlap area is larger to approach the total area.
