背景技术Background technique
牙体缺损是人类的常见病、除了牙体缺损外，牙齿畸形也是不容忽视的问题，随着生活条件的改善，人们对牙齿健康的重视越发增强，对牙齿美观也有了更高的要求，义齿修复是目前能解决这些问题唯一办法，目前，手工制作义齿仍然是国内医生典型的口腔修复方法，一般铸成金属修复体，考虑美观，在金属义齿上烤瓷，最后得到烤瓷义齿，烤瓷义齿制作过程都是手工操作，工序繁琐效率低、精度不高、周期长，另外，烤瓷牙咀嚼功能差，不能吃硬的食物，容易磨损，一旦表层烤瓷崩瓷，会露出金属冠底，影响美观。随着材料技术的发展，生物陶瓷的一系列优点在口腔修复领域得到发展，纯陶瓷材质义齿无论在性能，生物相容性，使用寿命及视觉美观上都远远优于金属合金材料.全瓷修复在义齿修复领域被认为是未来的主要发展方向，但是，全瓷修复只能借助于CAD/CAM技术自动加工成型，目前，已有的义齿修复CAD/CAM系统采用电机作动力带动金刚石车针对生物陶瓷块磨削成型。Tooth defect is a common human disease. In addition to tooth defect, tooth deformity is also a problem that cannot be ignored. With the improvement of living conditions, people pay more and more attention to dental health, and have higher requirements for the appearance of teeth. Dentures Restoration is the only way to solve these problems at present. At present, hand-made dentures are still a typical oral restoration method for domestic doctors. Generally, metal restorations are cast into metal restorations, considering the appearance, and ceramics are baked on metal dentures, and finally porcelain dentures are obtained. The production process of dentures is all manual operation, the process is cumbersome, the efficiency is low, the precision is not high, and the cycle is long. In addition, the porcelain teeth have poor chewing function, cannot eat hard food, and are easy to wear. Once the surface of the porcelain collapses, the metal crown will be exposed. ,Affect the appearance. With the development of material technology, a series of advantages of bioceramics have been developed in the field of oral restoration. Pure ceramic dentures are far superior to metal alloy materials in terms of performance, biocompatibility, service life and visual appearance. All-ceramic Restoration is considered to be the main development direction in the future in the field of denture restoration. However, all-ceramic restoration can only be automatically processed by CAD/CAM technology. At present, the existing CAD/CAM system for denture restoration uses a motor as power to drive a diamond car for The bioceramic block is ground into shape.
但现有的全瓷义齿CAD/CAM系统制作全瓷义齿首先必须通过专业软件建立所要制作的牙齿的CAD模型，根据义齿曲面的CAD模型，按照规划的刀具路径，通过刀触点及刀具形状进行数学建模，计算出磨削加工时数控机床的磨削刀具的刀位点数据，最后利用专业的数控机床在全瓷块上磨削加工，制作出全瓷牙齿，。However, the existing all-ceramic denture CAD/CAM system must first establish the CAD model of the tooth to be produced through professional software, and follow the planned tool path according to the CAD model of the denture surface, through the tool contact and tool shape. Mathematical modeling is used to calculate the tool position data of the grinding tool of the CNC machine tool during the grinding process, and finally the professional CNC machine tool is used to grind on the all-ceramic block to produce all-ceramic teeth.
现有的全瓷义齿制作系统主要存在两个缺点：There are two main disadvantages in the existing all-ceramic denture production system:
1：建立义齿修复体的CAD模型，需要昂贵的测量设备及开发专用义齿修复设计软件，可能还需要各种形态的牙齿数据库，技术复杂，成本高昂，对于我国的大多数普通患者在经济上难以承受。1: Establishing a CAD model of a denture restoration requires expensive measuring equipment and the development of special denture restoration design software. It may also require various dental databases. The technology is complicated and the cost is high. It is economically difficult for most ordinary patients in our country. bear.
2：义齿修复体曲面属于典型的雕刻曲面，但是义齿磨削刀具(金刚石磨针)的形状与传统的球型刀具及圆柱型刀具差异很大，属于锥形刀具，刀具顶部圆 钝，难以准确计算磨削加工时刀具的刀位点轨迹，这将导致全瓷修复体制作精度降低，甚至修复失败。2: The surface of the denture restoration is a typical engraved surface, but the shape of the denture grinding tool (diamond grinding needle) is very different from the traditional spherical and cylindrical tools. It is a conical tool with a blunt top, which is difficult to accurately Calculating the tool point trajectory of the tool during the grinding process will lead to a decrease in the manufacturing accuracy of the all-ceramic restoration, or even failure of the restoration.
有鉴于上述的缺陷，本设计人，积极加以研究创新，以期创设一种新型结构的全瓷义齿磨削系统的刀具轨迹测量仪，使其更具有产业上的利用价值。In view of the above-mentioned defects, the designer actively researches and innovates, in order to create a tool track measuring instrument of a new structure all-ceramic denture grinding system, so that it has more industrial value.

上述刀具轨迹测量仪100所用的原理如下：由于患者的牙齿缺损，需要对缺损的牙齿进行修复，首先由牙科技师利用现有的传统的牙齿取模技术制作出成本低廉的临时义齿200，临时义齿200的形状完全符合形状精度要求，并具有比较好的硬度。将临时义齿200固定在上述测量仪的临时义齿安装座232上，使用刀具5作为测量接触探针，按照磨削加工时的刀具5路径规划，刀具5在临时义齿200上完整滑行一遍，同时记录刀具5顶点的位置数据，就得到了磨削加工时的刀具运动轨迹数据，用此数据就可以控制磨削CAM系统的刀具轨迹，在全瓷毛坯块上磨出形状完全一致的全瓷材质的义齿修复体。The principle used by the above-mentioned tool path measuring instrument 100 is as follows: due to the tooth defect of the patient, it is necessary to restore the tooth defect, first the temporary denture 200 with low cost is produced by the dental technician using the existing traditional tooth impression technology, the temporary denture The shape of 200 fully meets the requirements of shape accuracy and has relatively good hardness. Fix the temporary denture 200 on the temporary denture mounting base 232 of the measuring instrument, use the tool 5 as a measuring contact probe, follow the path planning of the tool 5 during grinding, slide the tool 5 completely on the temporary denture 200 once, and record at the same time The position data of the vertex of the tool 5 can be used to obtain the tool movement track data during grinding. With this data, the tool track of the grinding CAM system can be controlled, and the all-ceramic material with the same shape can be ground on the all-ceramic blank block. Denture restorations.
该刀具轨迹测量仪100具体测量方法如下：在所发明的义齿刀具轨迹测量仪上，采用分层测量法，也就是将临时义齿200沿Z向分成一定数量的层数。每一层采用固定的间距，这样每一层的Z向距离数据可直接获得；只需测量每一层的X、Y向数据即可得到刀具5顶点的具体空间坐标值。X、Y向数据测量时，临时义齿200固定不动，操作者握住手柄43，向前推动手柄43上的滑杆42带动刀具5接触到限位块6，然后手动使刀具5沿临时义齿200表面在水平方向滑动一遍，由于刀具5与临时义齿200一直处于接触状态，在刀具5与临时义齿200接触滑动过程中，X向位移传感器33及Y向位移传感器41即可实时记录到刀具5顶点的X向和Y向位置数据，这样就得到了这一层义齿磨削刀具轨迹数据；测量下一层数据，电机21转动带动滚珠丝杠22转动，使竖直滑块231上升一个固定间距值，通过临时义齿安装座232带动临时义齿200实现了Z向上升一层距离，然后重复X、Y向数据测量，如此循环，直到测量完临时义齿200最下面一层数据，就得到了完整的义齿磨削刀具轨迹数据。The specific measurement method of the tool track measuring instrument 100 is as follows: on the invented denture tool track measuring instrument, a layered measurement method is adopted, that is, the temporary denture 200 is divided into a certain number of layers along the Z direction. Each layer adopts a fixed spacing, so that the Z-direction distance data of each layer can be obtained directly; only need to measure the X and Y-direction data of each layer to obtain the specific spatial coordinate value of the 5 vertices of the tool. During data measurement in the X and Y directions, the temporary denture 200 is fixed, the operator holds the handle 43, pushes the slide bar 42 on the handle 43 forward to drive the cutter 5 to touch the limit block 6, and then manually moves the cutter 5 along the temporary denture. The surface of the 200 slides once in the horizontal direction. Since the tool 5 and the temporary denture 200 are always in contact, during the contact and sliding process of the tool 5 and the temporary denture 200, the X-direction displacement sensor 33 and the Y-direction displacement sensor 41 can record the tool 5 in real time. The X-direction and Y-direction position data of the apex, thus obtained the tool track data of this layer of denture grinding; to measure the data of the next layer, the motor 21 rotates to drive the ball screw 22 to rotate, so that the vertical slider 231 rises by a fixed distance value, the temporary denture 200 is driven by the temporary denture mounting base 232 to achieve a layer of distance in the Z direction, and then repeat the data measurement in the X and Y directions, and so on, until the data of the bottom layer of the temporary denture 200 is measured, and a complete Denture grinding toolpath data.
综上所述，上述刀具轨迹测量仪100通过Z轴位移机构2、X轴位移机构3和Y轴位移机构4，实现只需要在临时义齿上手动仿型，模拟磨削运动，自动 记录生成刀具运动轨迹，不受刀具5形状限制，从而无需义齿的CAD建模，避免了通过复杂的算法计算加工时的刀具运动轨迹，降低了全瓷义齿制作的成本，适用于各种形状的刀具5，且能够克服上述缺点，所测量的刀具运动轨迹，可直接应用到义齿加工CAM系统上。另外，在刀具运动轨迹测量时，刀具5作为测头与临时义齿200是否处于接触状态的判断，不需要专门的接触传感器，仅凭操作者的手上的力感知。To sum up, the above-mentioned tool track measuring instrument 100 realizes only manual profiling on the temporary dentures, simulates the grinding movement, and automatically records and generates the tool through the Z-axis displacement mechanism 2, the X-axis displacement mechanism 3 and the Y-axis displacement mechanism 4. The movement trajectory is not limited by the shape of the tool 5, so CAD modeling of the denture is not required, and the calculation of the tool movement trajectory during processing is avoided through complex algorithms, which reduces the cost of making all-ceramic dentures. It is suitable for various shapes of tools 5, And it can overcome the above shortcomings, and the measured tool movement track can be directly applied to the CAM system for denture processing. In addition, when measuring the tool movement track, the tool 5 is used as the judgment of whether the probe is in contact with the temporary denture 200, and no special contact sensor is needed, only the force perception of the operator's hand is used.
