OBJECTIVE The production of similar specimens for material testing is very difficult and crucial. This has much influence on the results of an experiment. With CAD design and new printing technologies it is possible to create individual devices to produce specimens for different testing situations. In this study different devices were designed for the standardized production of tooth discs for testing with bonded materials. METHODS The different devices were designed using optimized CAD for 3D printing. After the design, the different parts of the devices were printed using a desktop SLA 3D printer with high precision. Three different tools were needed for the generation of a standardized disc. After the production, the different devices were tested on natural teeth. RESULTS It is possible to generate very precise tools for the creation of round tooth discs. 40 tooth discs divided into 4 groups with a thickness of 2.0 mm, 2.5 mm, 3.0 mm and 3.5 mm and a constant diameter of 5 mm were produced. For all groups the median of the diameter and thickness was under +/-0.05 mm and the lower and the upper quartile were all under +/-0.06 mm. SIGNIFICANCE With this new approach the creation of very precise and uniform tooth discs is possible. The whole process for the creation of the tooth discs was standardized.

CAD / CAM支持标准化厚度和不同厚度的牙釉质和牙本质牙盘的生产过程，用于体外材料测试。

目的生产用于材料测试的类似样品非常困难且至关重要。这对实验结果有很大影响。利用CAD设计和新的打印技术，可以创建单独的设备来生产用于不同测试情况的​​样品。在这项研究中，设计了不同的设备来标准化牙盘的生产，以便用粘合材料进行测试。方法使用优化的3D打印CAD设计不同的设备。设计完成后，使用台式SLA 3D打印机以高精度打印设备的不同部分。生成标准化光盘需要三种不同的工具。生产后，在天然牙齿上测试了不同的设备。结果可以生成非常精确的工具来创建圆齿盘。制成40个齿盘，将其分成4组，厚度为2.0mm，2.5mm，3.0mm和3.5mm，并且恒定直径为5mm。对于所有组，直径和厚度的中值均在+/- 0.05毫米以下，而下四分位数和上四分位数均在+/- 0.06毫米以下。意义通过这种新方法，可以创建非常精确且均匀的牙盘。创建牙盘的整个过程已标准化。意义通过这种新方法，可以创建非常精确且均匀的牙盘。创建牙盘的整个过程已标准化。意义通过这种新方法，可以创建非常精确且均匀的牙盘。创建牙盘的整个过程已标准化。
