[0034] 标记物为一个可反射红外光的小圆球,小圆球涂有反光材料,这样可方便红外摄像头记录其运动轨迹。 [0034] as a marker that reflects infrared light small ball, small ball is coated with a reflective material, which can facilitate the infrared camera records its trajectory. 测试标记杆后端由钢丝或塑料丝通过牙间隙固定在下颂切牙部位; 或者测试标记杆后端通过磁性装置固定在下颂切牙部位,比如用2个强力小磁铁把测试标记杆后端吸住固定好;或者测试标记杆后端通过压膜方式固定在下颂切牙表面,比如用弹性橡胶套或压膜将测试标记杆后端固定在4颗下颂切牙表面。 Steel wire rod from the back-end test marks or plastic wire through fixed mandibular incisor tooth gap sites; or test marks rod backend by magnetic means fixed mandibular incisor area, such as using two powerful small magnet to the back-end suction rod test marks stay fixed; or test marks rod through the back end fixed mandibular incisors laminated surface, such as an elastic rubber sleeve or film will mark the test rod is fixed at the rear end surface of the mandibular incisor 4. [0035] 红外摄像头通过可调整高度和角度的支架固定在测试者面部周围,采用至少两个红外摄像头。 [0035] infrared camera fixed testers around the face by adjustable height and angle brackets, using at least two infrared cameras. 例如,当采用两个红外摄像头时,其中一个红外摄像头可放于测试者面部正前方,记录测试标记杆前端的标记物的在额状面,即冠状面上的运动轨迹;另一个红外摄像头可放于测试者的侧面,记录测试标记杆前端的标记物的在矢状面上的运动轨迹。 For example, when using two infrared cameras, in which an infrared camera can be placed on the face in front of the test person, recorded in the frontal plane, i.e., the trajectory of the coronal plane of the front end of the rod test marks markers; another infrared camera can be placed on the side of the tester, the sagittal plane trajectory recording test marks the distal end of the rod in the marker. 两个从不同位置拍摄的运动轨迹组合起来,通过电脑中的坐标重建算法可得到测试标记杆标记物的三维运动轨迹,即对应符合测试者的下颂三维运动轨迹。 Two trajectories taken from different locations combine test marks obtained by computer markers rods in a three-dimensional trajectory coordinate reconstruction algorithm, which corresponds to the next song in line with the three-dimensional trajectory testers. 比如一个摄像头拍摄x(左右)方向和ζ (上下)方向,另外一个摄像头拍摄y (前后)方向和ζ (上下)方向,两个摄像头拍摄画面合在一块就能还原χ,ι, ζ三个方向的坐标。 For example, a camera to take x (left and right) direction and ζ (up and down) direction, while a camera captured y (front and rear) direction and ζ (up and down) direction, the two cameras shooting screen you can fit in a reduction of χ, ι, ζ three coordinate directions. 当然如果采用三个摄像头拍摄,效果会更好,但也增加了一些成本。 Of course, if the use of three cameras filming, the effect will be better, but it also adds some cost.

[0036] 系统通过电脑主机分析处理测试者的下颂三维运动轨迹,和标准下颂运动轨迹及阀值比较,具体是在张闭口、侧方运动、下颂前伸、后退、咀嚼运动等典型运动中下前牙切点的运动轨迹,由运动轨迹图的特征可以认识下颂肌肉功能紊乱的情况和牙齿咬合情况是否正常。 [0036] The system mandibular dimensional trajectory analysis and processing testers, and standard mandibular trajectory and threshold comparison by the host computer, specifically in Zhang closed, lateral movement, mandibular protrusion, back, and other typical chewing movement the trajectory of the movement of the lower front teeth cut-off point, the characteristic movement trajectories can recognize muscle dysfunction of the mandibular teeth bite situation and the situation is normal.

[0037] 如图3所示,本发明还公开了一种下颂运动轨迹记录方法,其包括以下步骤: [0037] shown in Figure 3, the present invention also discloses a mandibular trajectory recording method comprising the steps of:

[0038] 101、将测试标记杆后端固定在测试者下颂切牙部位,测试标记杆前端连接一个标记物露出口外并随下颂一起运动; [0038] 101, the rear end of the test mark rod fixed Chung incisor area, test marks a marker tip of the connecting rod is exposed estuary and mandibular movement together with the person under test;

[0039] 102、通过至少2个带红外发射装置的红外摄像头记录测试标记杆前端标记物的移动轨迹,将移动轨迹数据传送给电脑主机分析处理; [0039] 102, through at least two infrared camera with infrared-emitting device recording test marks lever movement locus of the tip markers, will transmit data to the host computer moving trace analysis process;

[0040] 103、通过在电脑中重建标记物的位移轨迹,对应反映了测试者下颂运动的三维轨迹,将记录的下颂运动三维轨迹和计算出的相关参数分别与系统存储的下颂标准运动轨迹和标准参数作比较,判断下颂运动和上下牙列咬合是否正常。 [0040] 103, by displacement track reconstruction in the computer markers, reflecting the corresponding three-dimensional trajectory testers mandibular movement, the next song will be recorded in the three-dimensional movement trajectories and related parameters are calculated and stored in the system under standard song trajectory and the standard parameters for comparison, judgment song movement up and down is normal dentition bite.

[0041] 具体的,本发明公开的下颂运动轨迹记录方法,包括步骤: [0041] Specifically, the mandibular trajectory recording method of the present disclosure, including the steps of:

[0042] 1、将2台带红外光发射功能的红外摄像头交叉固定于患者面部周围,其中一个红外摄像头可放于测试者面部正前方,记录测试标记杆前端的标记物的在额(冠)状面上的运动轨迹,另一个红外摄像头可放于测试者的侧面,记录测试标记杆前端的标记物的在矢状面上的运动轨迹。 [0042] 1, the infrared camera 2 units with infrared light-emitting function of the cross is fixed to the patient's face around, one of the infrared camera can be placed on the test's face in front of the recording test marks rod distal end of the marker in the amount (crown) trajectory shaped surface, another infrared camera can be placed on the side of the tester, and recording the trajectory of the rod in the sagittal plane of the distal end of the test marks in the markers.

[0043] 2、受试者端坐,双瞳平面与地平面平行,头位固定,肩部以上无支撑。 [0043] 2, the subjects sat, Double Vision plane parallel with the ground plane, the first bit is fixed, no more shoulder support. 将测试标记杆后端固定于测试者的下切牙上,测试标记杆前端的标记小球伸出口外。 The test marked the lever on the back-end is fixed to the lower incisors testers, test marks the tip of the rod protruding mark the ball outside. 测试标记杆后端由钢丝或塑料丝通过牙间隙固定在下颂切牙部位;或者测试标记杆后端通过磁性装置固定在下颂切牙部位;或者测试标记杆后端通过压膜方式固定在下颂切牙表面。 Steel wire rod from the back-end test marks or plastic wire through fixed mandibular incisor tooth gap sites; or test marks rod backend by magnetic means fixed mandibular incisor site; or backend test marks rod is fixed by the next song cut film tooth surface. 打开电脑主机中的下颂运动轨迹记录软件系统,并进行摄像头的校准,确认标记小球在摄像范围内,适当进行调整。 Open the host computer to the next song trajectory recording software systems and camera calibration, validation mark the ball in the imaging range, appropriate adjustments.

[0044] 3、嘱测试者保持牙尖交错位,并行张闭口运动,当获得连续6秒的稳定记录资料后,开始进行测试。 [0044] 3, instruct testers keep cusp cross-bit, parallel sheets and closing movement, after six consecutive seconds to get stable recording data, begin testing.

[0045] 4、当进行颂位及稳定性测试时,受试者叩齿2下,从姿势位(mandibl印osture position, MPP)开始记录,即从测试者闭口的静止姿势位开始记录,慢慢张口至最大位置, 然后慢慢闭口,下颂前伸至牙切对切回到闭口的静止姿势位,系统同步显示其运动轨迹及位移值,重复该运动至少2次,将数据传给电脑主机分析处理。 [0045] 4, when the song position and stability test, the subjects knocking teeth 2, began recording the postural position (mandibl India osture position, MPP), that is, from a stationary position testers closed position to start recording, Slowly the mouth to the maximum position, then slowly closed, the mandibular protrusion to cut teeth cut back on stationary posture closed position, the system simultaneously display its trajectory and displacement values, repeat the exercise at least twice, and the data to mainframe computer analysis and processing. 电脑主机中的控制软件分别求得2次以上在垂直方向、前后方向及侧方向的运动位移差,再分别求得垂直方向、前后方向及侧方向运动位移差的均值,分别与设定的阀值作比较,阀值设定范围是0. 05-0. 50mm, 可以依据测试者年龄、性别进行调整。 Host computer control software were obtained in two or more times in the vertical direction, the displacement movement of the longitudinal and lateral direction difference, and then were obtained in the vertical direction, the longitudinal and lateral direction of motion displacement deviations from the mean, respectively, the set of valve value for comparison, threshold setting range is 0. 05-0. 50mm, can be adjusted according to the test by age, gender. 比如设定阀值为0.25mm,若其中任一方向(垂直方向、前后方向、侧方向)的位移差大于0. 25mm,则表明该患者MPP-ICP不稳定,即下颂运动和稳定性不正常,需进行医治。 For example, the threshold is set to 0.25mm, if either one direction (the vertical direction, the anteroposterior direction, lateral direction) displacement difference is greater than 0. 25mm, it indicates that the patient MPP-ICP instability, namely the mandibular movement and stability is not normally, the need for treatment.

[0046] 当进行开闭口轨迹的运动速率及平滑度测试时,受试者从牙尖交错位(intercuspal position, ICP)开始记录,先自然开闭口1次,继而大而快地开闭口1次,将数据传给电脑主机分析处理,系统同步显示出2次运动的轨迹及速率。 [0046] When opening and closing tracks speed and smoothness of motion tests, the subjects began to record from the cusp staggered position (intercuspal position, ICP), the first natural opening and closing a second, and then a large and fast opening and closing 1 the data to the host computer analysis and processing, the system shows the trajectory and speed synchronous 2nd movement. 电脑主机中的控制软件将记录的下颂运动三维轨迹及速率与系统存储的下颂标准运动轨迹及标准速率分别作比较,判断这些轨迹的下颂运动指数是否一样,如果不同,则判断下颂运动和牙齿咬合不正常。 Host computer control software will record the song under the next track and three-dimensional movement rate system storage Chung standard trajectory and standard rates were compared to determine the trajectory of the mandibular movement index is the same, if different, the judge mandibular sports and teeth bite is not normal.

[0047] 当进行下颂边缘运动轨迹测试时,测试者依次完成最大开闭口运动,最大前伸运动,最大左、右侧方运动,要求每项运动都以闭口的静止姿势位为起点及终点,将数据传给电脑主机分析处理,系统同步记录显示下颂边缘运动轨迹。 [0047] When the next song Kinesiographic test, the tester in order to complete the maximum opening and closing movement, maximum protrusive movement, the maximum left and right side of sports, requiring each sport are still in the closed position for the start and end position the data to the host computer analysis and processing, the system displays simultaneously recorded marginal mandibular trajectory. 计算及比较这些轨迹的下颂运动指数(mandibular movement index,MMI),MMI主要利用冠状面轨迹进行。 Calculation and comparison of these tracks mandibular movement index (mandibular movement index, MMI), MMI mainly use the coronal plane trajectory. 电脑主机中的控制软件比较最大开闭口运动中的开口轨迹和闭口轨迹之间位移距离是否超过规定的阀值;或者系统比较最大前伸运动中的开口轨迹和闭口轨迹之间位移距离是否超过规定的阀值;或者系统比较最大左、右侧方运动中的开口轨迹和闭口轨迹之间位移距离是否超过规定的阀值。 Displacement distance between the host computer in the control software compares the maximum opening and closing movement of the opening in the closed track and the track exceeds a prescribed threshold value; displacement or the distance between the system comparing the maximum protrusive movement trajectory and opening exceeds a predetermined closed trajectory threshold; or system displacement distance exceeds a predetermined maximum threshold value comparison between the left and right side of the opening movement trajectory and closed track. 如果判断超过阀值,则表明对应某个方向的咬合与肌功能不协调。 If the judge exceeds the threshold, it indicates a direction corresponding to bite and uncoordinated muscle function. 阀值设定范围是0.20-0. 60mm,可以依据测试者年龄、性别进行调整。 Threshold setting range is 0.20-0. 60mm, can be adjusted according to the test by age, gender. 例如,正常开、闭口轨迹是基本一致的,对于25岁的男性,如果最大开闭口运动中闭口轨迹脱离开口轨迹距离过大,超过0. 5mm 以上,则表明咬合与肌功能不协调,需医治。 For example, normally open, normally closed trajectory is basically the same for the 25-year-old male, if the maximum opening and closing movement of the track from the opening track closed the distance is too large, more than 0. 5mm or more, then the occlusal disharmony and muscle function, you need to heal .

[0048] 图4为利用本发明建立的系统拍摄的正常下颂运动轨迹记录模式图。 [0048] Figure 4 shows the use of the system of the present invention is taken to establish normal recording mode mandibular trajectory map. 其中左侧图为矢状面边缘运动基本图形:记录了最大张闭口运动,最大前伸及后退运动。 Pictured on the left edge of which the sagittal plane motion graphics primitives: Zhang recorded the maximum closing movement, maximum reach and backward movement. P点表示最大前伸位;0点表示最大张口位;RCP点表示后退接触位;ICP点表示最大牙尖交错位。 P point represents the maximum protrusion position; 0:00 represents the maximum mouth bit; RCP point represents the receding contact position; ICP point represents the maximum cusp interleaved bits. 正常情况下,从最大前伸位⑵到最大张口位(0)轨迹恒定,从前上到后下呈一光滑曲线,而前伸轨迹(即ICP点至P点轨迹)受切导影响,曲线较不规整。 Under normal circumstances, the maximum reach to the maximum bit ⑵ mouth bit (0) tracks a constant, from the front to the rear was a smooth curve, and reach the track (ie, point-to-point P locus ICP) cut guide affected by the curve is irregular.

[0049] 图4中右侧图为冠状面边缘运动轨迹,反映最大张口及最大侧向运动。 [0049] FIG. 4, right-hand edge of the picture shows the coronal plane trajectory, reflecting the biggest mouth and the maximum lateral movement. R点表示右侧边缘运动咬合位;L点表示左侧边缘运动咬合位;0点表示最大张口位;ICP点表示最大牙尖交错位。 R point represents the right edge of the movement bite position; L point represents the left edge of the movement bite position; 0:00 represents the maximum mouth bit; ICP point represents the maximum cusp interleaved bits. 正常情况下,张闭口运动为垂直方向居中的直线(左右方向弯曲变化不大); 侧向边缘运动左右基本对称。 Under normal circumstances, Zhang and closing movement of the vertical direction center line (lateral direction bending little change); the lateral movement of the left and right edges substantially symmetrical. 从侧向边缘咬合位到最大张口位的轨迹比较稳定(即R点或L点至0点轨迹)。 Occlusal position to the maximum from the lateral edge of the mouth bit more stable trajectory (ie, R-point or point-to-L track 0:00).

[0050] 图5为一左侧咀嚼及张口疼痛病人的下颂边缘运动轨迹。 [0050] FIG. 5 is a left side edge of the trajectory of the mandibular chewing and mouth pain patients. 各方向的运动轨迹,特别是左侧边缘为张口轨迹异常,各转折点较偏离正常边缘运动模式图,且以患侧显著。 Trajectory of each direction, in particular the left edge of mouth abnormal trajectory, each edge turning point deviates from the normal movement pattern than FIG, and significantly affected side. 此外,运动范围,特别是张口度减小。 In addition, the range of motion, especially mouth opening is reduced. 左右侧向运动、垂直张闭口运动轨迹出现不规则偏摆,估计该患者出现关节内紊乱,导致张口型的变异,而前伸轨迹的短且不规则,提示可能该患者有覆牙合深、覆盖浅的咬合状况。 Left lateral movement, vertical Zhang closed trajectory irregular yaw, estimated that intra-articular disorder patients, leading to mouth type of variation, and reach short and irregular trajectory, suggesting that patients with deep overbite, covering the shallow bite situation.
