When it is about restorative dental materials, aesthetics is traditionally preferred. This has led to the selection of materials very visually similar to the enamel, but unfortunately, their mechanical properties are not similar. This often translates into disadvantages than advantages. In the present work, a comparison is made of the stresses that occur during dental occlusion (dental bit) in a healthy dental organ and those that are generated in a dental organ with a dental zirconium restoration. Numerical simulation was carried out by means of the Finite Element Method, in computational biomodels, from Cone-Beam Tomography, to obtain the stresses generated during dental occlusion. It was found that the normal and von Mises stresses generated are substantially greater in the molar with restoration compared to those produced in the healthy molar. In addition, the normal function of the enamel and dentin to disperse these stresses to prevent them from reaching the pulp is altered. Therefore, it is necessary to analyze the indiscriminate use of this restoration material and consider other aspects, in addition to aesthetics and biocompatibility for the choice of restorative materials such as biomechanical compatibility.

牙科锆修复体及其在牙齿组织中产生的应力的数值分析。

当涉及修复性牙科材料时，传统上首选美学。这导致选择了在视觉上与搪瓷非常相似的材料，但不幸的是，它们的机械性能并不相似。这通常转化为弊大于利。在当前的工作中，比较了在健康的牙齿器官中在牙齿咬合（牙咬）期间产生的应力和在具有牙齿锆修复体的牙齿器官中产生的应力。通过有限元方法，在锥形束层析成像的计算生物模型中进行了数值模拟，以获得在牙合过程中产生的应力。发现正常人和冯·米塞斯与健康磨牙相比，修复后的磨牙产生的应力明显更大。另外，改变了牙釉质和牙本质分散这些应力以防止它们到达纸浆的正常功能。因此，除了选择美学和生物相容性之外，还需要分析这种修复材料的随意使用并考虑其他方面，以选择诸如生物力学相容性的修复材料。
